Issue #105, Apr 2009 - Gemini Gems

Volume 105 April 2009
Gemini 105M, Hull 559, owned by Eric Booton
on the St. Lucie River near Stuart Florida
Editors: Mark & Louise Kiehl
Contributing Editors for this issue: Jim Fish, Jim Faughn, Capt. Bill Schardt, Bill Scarpino, Laura Hershfeld, Sandy Graves, Ron
Adkins.

At present, over 1000 Gemini catamarans are in existence worldwide, spanning five major model revisions. In the
interest of extending support to owners, Performance Cruising will be offering several new channels of service, with
some of that delivered directly through Gemini Gems. Over the next few months, we will begin offering the following
new content:
• Articles and technical bulletins from Performance Cruising.
• An online moderated forum that will include feedback from Performance Cruising.
It has now been a year since I took over the newsletter from Jill & Tim Argie. At this point I have been through a
complete business cycle in terms of publishing newsletters, processing memberships, and taxes. The data I collected
enabled me to review the newsletter balance sheet. What I found is that despite the fact that I receive no compensation
for my time, we are now operating at a loss. .
Last year at this time the business was not generating a loss, however a lot has changed since then. Printing and
postage, our largest expenses, have increased dramatically. We are also losing money on every burgee we sell. A
very small profit is realized on the recently released floor mats that you can purchase at a discounted rate. We make
nothing on any apparel you can purchase directly from Land's End.

Despite the increase in expenses, I feel the value to the members has increased substantially. We have worked hard
to solicit high quality newsletter content. The web site provides many new functional features to assist members attempting
to locate information quickly. Classified ads now feature pictures online, and members can create/delete/
edit them on their own. As of this issue, all of the past newsletters are available online with pictures. Article titles and
keywords are indexed and categorized so that you can quickly identify articles of a specific type (rendezvous, operational,
maintenance, upgrades, destination, etc.).
Effective this issue we are restructuring Gemini Gems in order to address the financial losses and to promote the additional
content from Performance Cruising:
• The new price for the printed newsletter and online resources will be $39/year. Existing web and newsletter subscribers
will be grandfathered in.
• The printed and online newsletter will continue to be issued quarterly (Jan, Apr, Jul, Oct). Back issues of newsletters
published after this issue will be available for purchase in electronic format (pdf) at $10 each.
• The annual directory will be published in printed and online form in February.
• Classified advertisements are free for up to 4 issues (1 year), thereafter $9/ea. In order to allocate more newsletter
space for articles, boat ads will be abbreviated to a simple list in the printed newsletter (full ads can be viewed
online). Non-boat ads will be included as usual but with length restrictions.
• Members who contribute an article will receive credit of one issue (3 months) per full final edited page.
A few other changes will be implemented in the interest of allowing me to focus on newsletter editing and publication:
• Passwords resets have been simplified and you can do it yourself very easily by simply entering your login email
(the email address associated with your account). You are provided real time feedback if the login email you enter
is correct or not. You can revise and manage your login email by logging in and editing your profile. I will
continue to respond to email requests for an unknown login email.
• Privacy options. You now have privacy options that allow you to choose to not share your street address, email
and phone number with other members online, in the annual printed directory, and with Performance Cruising
Inc. You can revise these options by logging in to your account online and modifying your profile.
• Classified. You can create a classified ad yourself online and even add a picture. All classified ads must be
'renewed' by clicking on an email link sent to you automatically 30 days before the next issue is released, otherwise
they will not be included in the next printed issue or online. You may also denote the item as sold, cancel
the ad, or you may edit the ad.

Spinnaker Use on a 3400
By Jim Fish, FISH TALES, Hull 442
In March of 2008 I purchased a spinnaker and related
hardware for my Gemini 3400 FISH TALES. The
asymmetrical pole-less cruising spinnaker is from
UK-Halsey (http://www.ukhalsey.com/sails/
triflasher.asp). They call the spinnaker the ‘Flasher’,
and it is available in two construction styles - The
Matrix and Tri-Radial. The cost was about $1,600,
including everything but the halyard.
View of the UK-Halsey ’Stasher’ sock.
The fish head logo was added to the sail by UK-
Halsey using an AutoCAD drawing I provided.
A spinnaker masthead crane was added
to the top front side of the masthead,
forward of the existing roller furling to
accommodate the spinnaker halyard. .
5

The halyard layout picture shows the setup.
The tack of the sail is on a six foot line tied
off to the base of the existing genoa bracket.
This allows the crew, with two additional
lines, to pull the tack to port or starboard in
the middle of the jibe. With the sock, the
Flasher can be set, trimmed and lowered by
one person and an autopilot.

Replacing the Transmission - Gemini 105M
By Jim Faughn, FREEDOM, Hull 536, 105M
I encountered a problem with the engine speed, changing
from 2650 up to 2750 and back down again. Originally
this was sporadic, but in October of 2007, it became
more frequent with a larger RPM change.
After checking the engine and changing the oil in the
transmission several times, I began to believe the
transmission clutch was slipping. Sailcraft Service in
Oriental, NC confirmed my diagnosis. Unfortunately,
you can't easily rebuild the transmission on the Gemini,
as parts are hard to find in the US. After many
phone calls by Sailcraft, Phil found the only part available
in the US, unless I wanted to wait at least 12
weeks. Since I did not wish to wait, the part was obtained
from Torrenson Marine, as they took it off a
new engine transmission set.
came forward first, keeping the transmission low, in
order for removal to be realized. There is only about
1/8 inch clearance on each side. The engine was successfully
removed and rested on cardboard in the cockpit.
The engine successfully removed and resting on cardboard.
The engine and transmission had to be tilted just right in
order to remove them from the engine compartment.
I moved my boat to Sailcraft Service and spent the afternoon
disconnecting everything from the engine, preparing
it for removal. I enlisted my mechanic Eric, formerly
a Porsche and Mercedes mechanic. We worked
as a team to remove the engine from FREEDOM, utilizing
a chain on the lift points after removing all the
motor mounts. The positioning was critical, the engine
There were several issues that I intended to address
while the engine was out. We removed the transmission
along with the heat exchanger. The heat exchanger
needed to be cleaned, and I had to free-up the
bolt on which the alternator pivots. With the cleaning
completed, I could see a difference in the water flow
and was happy we chose to do the job. I also had purchased
a new starter, planning to use it as a spare.
However when we took the old one off, seeking access
to the transmission, we found it was a difficult job due
to access limitations. Consequently, I decided to install
the new one while on land, keeping the old one as the
spare. Hopefully I will not have to do this while underway.

since it was easily accessible.
Three hours in to the project, the transmission and heat
exchanger now looked great after a fresh coat of paint.
While the engine was out, I cleaned the compartment
with bleach to remove old stains. Approximately 24
hours later, we had the engine and the transmission
back in, and in another hour we had the engine aligned
and had tightened down the motor mounts. We replaced
the rear mounts, as one of them was bad.
In the picture above you can see the new transmission bell
housing to the left and the old one to the right. Other than a
little grease on the old unit, no difference between them.
We found some other issues while the engine was out.
The port side of the transmission hose showed wear.
Ultimately we found that the port side motor mount
was very close to the hose, resulting in this wear spot.
We replaced the hose and added chafe protection. If
you are a Gemini owner, you may want to check the
wear and add chafe protection as well. I also found the
exhaust hose was going bad, when I removed the 45
degree elbow that I was replacing. I had already purchased
a new elbow, based on the recommendation
from Westerbeke, installing it along with the exhaust
hose. In addition, I also replaced the vibration dampener
plate between the engine and the transmission
Wear spot found on the port transmission hose.
Old (left) and freshly painted replacement (right)..
The next day I reinstalled all the hoses and electrical
connections. Shortly thereafter, I had the engine running
again. Since I had to drain all the antifreeze, I
spent almost an hour getting rid of all the air locks in
the block by filling, running, stopping, filling, etc. I
finally had it all working great. As you can see in the
photograph, the electrical connections in the lower
right, had corrosion on them. To alleviate future issues,
I applied dielectric grease on the same. I also found
two more places where I added chafe protection
(rubber held by wire ties); the throttle and stop cables
Additionally I found the raw water intake line could
rub on the starboard aft motor mount, so I added rubber
protection on that hose as well. The new engine
motor mounts were aligned perfectly in the horizontal,
and under three thousandths in the vertical.
In retrospect, I did several things which made the project
easier. First, I took many pictures of all the items.

hoses and electrical connections.
Second, I used cardboard to line the cockpit, which
really saved on clean up time. Third, I found a company
that would allow me to work along with their mechanic,
in order to reduce cost.

Since the repair, we have been to the Bahamas, Key
West, back to Kentucky Lake for hurricane season,
and we are now spending the winter in Key West. Everything
is still working fine. You can see more about

Captain’s Corner
Top Ten Reminders For Spring Commissioning
By Capt. Bill Schardt, CATNIP, Hull 892
1. If you removed the raw water impeller, last fall,
inspect it and reinstall it before you attempt to start
the engine.
2. Remove any rags from the intake and exhaust.
3. Check the fluid levels in the engine, transmission
and drive leg and top off as necessary with the
proper fluids. Before adding any fluid to the transmission,
make sure that you know which transmission
you have and what fluid to use. There is an
identification plate next to the transmission dipstick
that will identify your transmission type.
Your Westerbeke Owner’s Manual will have the
correct fluid type for your transmission. You need
to check your own, because Westerbeke has used
several different transmissions for the Gemini.
4. Check the condition of the engine zinc and replace
if necessary.
5. Ensure that all batteries onboard are topped off
with distilled water and fully charged.
6. Inspect and grease all fittings on the outdrive leg.
Make sure that the reverse latch is operating
smoothly and apply a liberal amount of grease to
all moving parts.
7. Inspect all through hull fittings for leaks and ease
of operation and make sure they are in the proper
position to operate the boat.
8. Check the expiration dates on any safety equipment
such as flares and ensure that the pressure
gauge on fire extinguishers is reading ok.
9. Inspect all of your running lights for proper operation.
10. Start the engine and inspect the exhaust for the
presence of water.
Oh, and #11. Release the spring line before leaving
the dock. :-)

Facnor Mast Furled Main
By Bill Scarpino, DOUBLEWIDE, Hull 623
OK, I did it. I opted for ease of use and safety. I installed
a Facnor behind-the-mast furled main.
In retrospect it was a good decision. The boat is
cleaner at anchor. I no longer have to wash the bird
droppings off the canvas cover. No longer have to replace
the canvas cover. No longer have to wrestle it on
as it shrinks over time. Not big issues I agree!
Safety first! Reefing is quite flexible as you can set the
sail at any position from fully extended to completely
reefed. The lines control the sail very well so, once set
they can hold the sail on a stiff breeze.
As with any reefing, the rule is to reef early before you
need to do so. You also need to come into the wind
and hold on that bearing while the reef is taken.
How does she sail Good question. Here is my experience.
With a following sea of 6-8 feet and a wind 120
degrees off the bow at 20-25 knots Doublewide
reached as high as 11.25 knots on the downside of the
swells (some felt like waves!). In general we were
holding a pretty healthy 8.5 to 9 knots. Upwind in 2-4
foot swells and 12-15 knots of breeze 6 to 6.5 has been
my typical experience.
Yes, the sail area has been reduced a bit but I like the
convenience and safety of the furling system. I don’t
feel I have given up much in the way of speed and no
discernable loss in the ability to point. It will work
even better when I replace the sail with a slightly
lighter fabric.
11
Editor’s note: The furled mainsail is contained in a
housing section attached to the mast sail track. The
installed housing requires no alteration to the mast
and the original main sail may be used. For more

Upper Chesapeake Bay Destinations - Chestertown
By Mark Kiehl, SEAS TODAY, Hull 649
Every summer sailing season on the Upper Chesapeake
Bay, I try to visit somewhere new. Based on the
weather and length of our time off, we decided to explore
the Chester River and Chestertown last summer.
Chestertown located at 39°13′10″N 76°4′6″
W / 39.21944°N 76.06833°W (39.219328, -
76.068424) is a small town on the East side of the Upper
Chesapeake Bay, an approximate 24 nm trip from
the mouth of the Chester River.
Chestertown
As we began our sail up the Chester River, bad
weather was approaching, so I ducked into the Corsica
creek to anchor in a safe location. This creek had been
on my short list of recommended stops by other cruisers,
and I was not disappointed. The scenery was very
pretty, and the homes sparsely located along the shoreline
were impressive as well.
Within the first 12 nm of the mouth of the Chester
River are a number of smaller rivers and creeks for the
cruiser to explore.

We departed from Middle River, two rivers North of
Baltimore (Patapsco) and arrived at the mouth of the
Chester River late afternoon. The weather predicted
possible thunderstorms, so I watched the weather radar
carefully using my mobile telephone’s internet capability.

The next morning we began our adventure up the
Chester River toward Chestertown. As we traversed
up the river, it became more and more narrow. We
enjoyed observing the many beautiful estates and the
interesting boats we passed along the way.
As we walked around Chestertown, we noted a number
of visitors by land. It appears that tourism is an important
industry to the town and it is well supported with
interesting shops, restaurants, and lodging.
Just prior to noon we arrived at Chestertown. You
cannot go up the river any further than this point due to
a bridge just east of Chestertown. A fuel dock and a
couple of marinas are available.
This was one of the few marinas we spotted along our trip up the Chester River. It is called Rolph’s Warf and it appeared to have
numerous amenities in this five acre property including a fuel dock, slips, lift, beach, and a Victorian Inn called ‘River Inn’. Address:

Master Stateroom Overhead Reading Light Options
By Sandy Graves, LILY PAD, Hull 944
Installing overhead individual reading lights in the
master stateroom of a 105Mc is somewhat of a challenge.
Ideally you could lug off the existing overhead
12V light, however the wiring runs behind the liner,
and finding a way to make an attractive installation
from that is the problem.
The final lighting and control panel viewed from the master stateroom looking aft.
Using the wiring from the fans mounted on the dinette
side of the main bulkhead is also problematic, but can
be accomplished. It would necessitate running the
wires up to the lip of the headliner, along the bottom of
the headliner, then drill holes through the bulkhead at
an acceptably discreet point, and finally running the
wires down a short distance to individual reading
lights. The exposed wires could be covered with a
decorative teak strip. Others have successfully run wiring
behind the headboard and mounted goose-neck
lights at the top which is both attractive and significantly
easier than the previously mentioned solution.
There is another option that not only solves the wiring
difficulties but also allows for a positive change in the
use of another light, the deck light. The final product is
a lighting area above your head and out of the way,
that allows three different uses; 1) reading lights used
separately or simultaneously, 2) operate the deck lights
from your bed, 3) utilize the red night light anytime in
combination with the previously mentioned.
Since you rarely would
need both interior reading
lights and deck lights simultaneously,
you can
elect to obtain their power
from the same source by
running the wires through
a three-way switch. The
deck light switch at the
master electrical panel is
left in the "on" position
continuously, unless you
need to disrupt the power
for maintenance. The red
night light is lugged off
the power source and is
controlled by a distinct
toggle switch that can be
felt in the dark. If you
need to turn on the night
lighting in the master
stateroom without instantly destroying your night vision
with white light, this is an important feature. The
toggle switch toggles in all directions, so you only
need to push it sideways on contact. These are available
at Wal-Mart in the automotive electrical section.
If you examine the wiring behind the headliner cover
directly under the mast, you will see that you can use
the deck light positive wire as a source for the reading
lights, as well as the red night light. Pictured here is
the finished product on LILY PAD. As you can see,
the cover is clad in vinyl to match the headliner. For
decorative reasons, as well as thickness requirement
(1/16th of an inch), I glued a piece of teak colored
plastic laminate to the face of the cover on which the
switches would be fastened.
15

To do this installation you need the following items:
1. Two swivel head 12V reading lights with individual
on/off switches ($9 on E-Bay)
2. One automotive red truck DOT light (any automotive
parts store)

I made a negative buss bar from a wire terminal by
running a continuous wire down one side of the terminal
screws and fastened it to the back side of the cover.
In addition (but not shown), I attached the existing terminal
block located behind the cover, to the cover itself,
to facilitate working with the wiring and to dress
up the jumble of wires located at the base of the mast.

The installation is pretty straight forward. The biggest
problem I encountered was finding a comfortable way
to sit/kneel while doing the wiring. We have used the
lights regularly for the past month and so far haven’t
found a down side. We will be
switching to LED bulbs once
these bulbs burn out. The red
night light bulb is very small and
only uses about 0.3 amps. It gives
the stateroom a very cozy glow
that comes in handy for occasions
other than sparing your night vision.
On a scale of 1 to 10 . . . it’s
a 10.

Gemini 3000 Headliner Replacement
By Ron Adkins, DOVE, Hull 153
I can still remember the day we looked at our 1985
Gemini 3000 for the first time. We had made arrangements
to meet the owner at the dock where he kept it
moored. After looking at the outside, we entered the
cabin to take a look inside. Immediately, my wife’s
eyes went to the headliner. I knew exactly what she
was thinking. It looked awful and I knew she did not
like it. As I was talking with the owner, she gave me
the silent “Hand cut across the throat” behind his back.
She did not want to buy this boat. In her opinion, the
interior was just not acceptable.
After we left the dock and got back in our car, my wife
did not waste a second before she expressed her feelings
on this purchase. What really stuck out in her
mind was the unsightly headliner. I spent the entire
trip home trying to convince her that I could restore
this Gemini. Somewhere in the discussion, I promised
that I would deal with the headliner issue also.
Early in the restoration project, I removed the headliner
in the main cabin. I did not have a clue as to how
I would replace it, but I knew that it had to be done.
After some research on what other Gemini owners had

done and also what other boat owners had done, I decided
to install panels instead of the factory type vinyl
headliner. I liked the idea of having panels that could
be removed for maintenance, that would not sag, could
be installed one piece at a time, and installed by me. I
am more of a carpenter than a seamstress!
I realized that lots of decisions would have to me made
in order to install the panels. What type of material
would I use to fabricate the panels Would I cover the
panels with a fabric and if so, what type of fabric
would I use Other considerations were, how I would
secure the panels to the ceiling, how many panels
would I install, and what type of trim would I use.
I wanted the panels to be light, yet I wanted them to be
somewhat rigid. I finally decided to use ¼” fir plywood
for the panels. It was inexpensive and easy to
shape. I later decided to cover the plywood with white
Formica. Initially I was concerned about the added
weight of using these materials. However, I believe the
total weight is less than 100 lbs., including the trim. I
hate adding weight, but I thought it was a good price to
pay to have a nice looking headliner.
The process of fabricating the panels was quite easy.
First I made two pieces that mounted in the corners of
the ceiling just over the windows on the port and starboard
sides. These sections were cut to adapt to the
curves of the ceiling and to provide a straight edge for
the main ceiling panels. I then cut four panels to fit in
the main cabin. I assembled the entire headliner (6
pieces) first without the Formica to ensure the fit was
correct. I then removed the six pieces and covered
them with Formica. After covering the plywood panels
with Formica, I coated the backsides with polyurethane
to provide some waterproofing in case I ever develop
a leak above the panels.
Next in the process came the trim. My first thought
was to use teak. However it is expensive and it would
have to have a finish applied to match the other teak in
the boat. Also, the older Geminis already have a lot of
teak in the cabin which darkens the cabin, gets dirty
easy, stains easy, and has to be maintained. I decided
to use white PVC trim, which is available from Home
Depot. It is easy to shape, easy to clean, waterproof,
and it matched the Formica without being painted. The
final look was a clean looking all-white headliner.
I used stainless wood screws to fasten the panels to the
ceiling. The plywood with the Formica attached was
rigid enough so that a few screws would hold each
panel. (I hate drilling holes anywhere on a boat). Basically,
the panels are held by screws under the trim
around the hatches, the trim on the walls, and the trim
between the panels.
The panel idea worked so well, I decided to install
panels in the aft staterooms. This was really easy. I
installed one panel in each room held in place by four
pieces of trim. The head and the master stateroom
were a different story. I had a difficult time trying to
design a way to install panels without making them
look tacky. The ceilings in both of these rooms are
curved in two directions making it difficult to install
panels without having several seams and lots of trim. I
ended up sliding Formica into the ceiling and securing
it with just a few screws around the hatches and a couple
of pieces of trim. These headliners turned out very
nice. The Formica fit tightly in the ceiling, yet it can be
removed quite easily if I need to gain access to the area
above.
My wife and I are very pleased with the new headliner.
It completely changes the appearance of the cabin area
of the boat.
If you own one of the older Geminis, then I know you
can identify with my headliner dilemma. I have posted
additional pictures at http://www.flickr.com/photos/

email me with any questions that you have and I will
try to answer you.
Good sailing!
Editor’s Note:
Ron plans to launch his 3000 early this summer and will keep
it on the James River, a few miles north west of Norfolk VA.
