HydroTrim
The Harken HydroTrim is true push-button sailing for main and headsail sheeting.
Using a 1:4 or 1:6 reverse purchase, it solves the problem of winches that tail
line into the cockpit—the hidden belowdecks or in-boom purchase contains all
line within the system and saves valuable space on deck.
The cylinder is affixed to the hull or frame with a two-piece retaining bracket.
This one-time installation allows the cylinder to be easily removed and serviced
without unbolting anything from the hull. The blocks can be removed from the
cylinder ends with a single pin so you can service them offsite or leave the
rigging intact while servicing the cylinder. Two smaller low-friction sheaves on
the cylinder ends replace the larger diameter sheaves typical of most belowdecks
trimming systems, reducing the overall length of the system and allowing
installation into smaller spaces.
Cylinders feature bronze-filled Teflon ® bearings that maintain piston and rod
alignment longer than common acetal bearings. Graphite-filled Teflon ® rod seals
and bronze-filled Teflon ® piston seals are extremely low friction and are more
durable than polyurethane seals. Performance O-rings and slant springs in the
nonabsorbent Teflon ® cylinder seals provide consistent seal pressure for a
reliable long-lasting fit. Cylinders, rod, T-Track, and mounting brackets are
made with Hardkote-anodized, Teflon ® -impregnated 6061-T6 aluminum.
All fittings and fasteners are stainless steel.
Custom cylinder lengths are available.
