<strong>Gemini</strong> 105Mc Owner’s <strong>Manual</strong><br />
Hauling and Trucking the <strong>Gemini</strong><br />
With the <strong>Gemini</strong>’s straight keels, hauling the boat is<br />
a relatively easy procedure. The straps of the lift<br />
will go right under both hulls and since the straps<br />
do not stretch there is no tendency for them to<br />
crush the hulls.<br />
Once the boat is out of the water it can simply be<br />
placed on top of four piles of cinderblocks with four<br />
blocks in each pile; making a square pile. The<br />
blocks should be 16’ apart front to back. Place the<br />
front two piles of bricks under the bulkhead at the<br />
back of the buoyancy tanks in the bow. The correct<br />
placement is parallel with a line 4” forward of the<br />
toilet through hull on the port side.<br />
Place the rear two piles under the front edge of the<br />
aft bed. The correct placement is a parallel line 1’<br />
ahead of the outside aft cabin window which is<br />
inline with the bulkhead in front of the aft bunk.<br />
Place a piece of 1” thick plywood about 18" square<br />
(a 2 x 12 cut to 30” running for and aft would be<br />
even better) between the blocks and the hull. Be<br />
sure to bring the bow of the boat down first (until<br />
the straps are loose) and then the stern. When the<br />
stern is about 1” away from the blocks, insert shims<br />
so that each hull is an equal distance from the<br />
blocks. The aim is to distribute the boats weight<br />
over the four blocks evenly. Wedge under the wood<br />
so that the plywood follows the angle of the bottom<br />
of the hull. It is important to evenly distribute the<br />
load over as large an area as possible so as not to<br />
place a point load on the hull.<br />
Trucking the <strong>Gemini</strong><br />
Hauling and Trucking<br />
At 14' wide, the <strong>Gemini</strong> can be trucked anywhere far<br />
easier and for less expense than any other cruising<br />
catamaran. However, the transom and rudders must<br />
be lifted above the rear wheels of the truck.<br />
The flat bed of the truck is normally 8' wide but the<br />
keels of each hull are 10' apart. This requires two<br />
large timbers placed on the flat bed for the boat to<br />
sit on. These timbers should be 10" x 12" x 14' long.<br />
They are placed 16' apart on the flat bed. The front<br />
timber will be directly under the bulkhead at the<br />
back of the forward buoyancy tanks. (roughly 6’ back<br />
from the bow) The rear timber will be under the<br />
bulkhead in front of the aft bunks. (located at the<br />
same places as the cinderblocks when storing the<br />
boat) Then a series of wedges about 4" high must be<br />
nailed to the timbers at the sides of the hull to give<br />
additional side support and stop the boat from moving.<br />
Place carpet between the hulls and these timbers<br />
and wedges to prevent any scratching of the<br />
gelcoat.<br />
Once the boat is in place, use a chainsaw to remove<br />
as much excess wood from the ends of the timbers as<br />
possible. Tie the boat down with lines going from<br />
the four corner cleats diagonally down and back to<br />
the flat bed. This will prevent movement up and<br />
down as well as back to front. The timbers must<br />
also be chained to the truck. Also, to stop the centerboards<br />
from hitting the road should they fall<br />
down, take a line from the stanchion above the centerboards<br />
down under the hulls to the truck.<br />
