foredeck cleat and then connected to the towing vehicle.
Independent wiring avoids the frequent breakdowns that
occur with wiring through the trailer being attacked by
saltwater. When the trailer is being towed on its own, the
lights can be mounted directly to the trailer.
Before trailering, check that tires are inflated correctly, the
beam locking pins are in place, the rudder is fully up and tied
to one side, the pop-top or hatch is secured, and the boat is
tied down to the trailer. There should be one tie-down per
side, these being looped around the winches or brackets on
the cockpit coamings, and tied to the tie-down loops on the
trailer. The bow eye should also be tied down to the winch
post, in addition to the winch line. Check that all the trailer
supports always bear equally against the hulls.
When trailering, BE SURE to pivot up or remove the
trailer jockey wheel, and that the hitch is locked on to the ball.
Should the mast extend back past the trailer lights by
more than the legal amount, the appropriate warning flag
should be tied on the back. The mast can be positioned far
enough forward to eliminate any excessive overhang, but
this may not be possible if the towing vehicle is a van.
When trailering, always allow extra distance for stopping.
Particularly watch for low bridges, overhanging trees or
awnings etc. If necessary, the boat can be partially unfolded
on the trailer in order to pass under a low bridge.
The daggerboard SHOULD ALWAYS BE DOWN when
motoring, to prevent any sideways movement. If not, the
boat will have a hovercraft like motion with wide skidding
turns. With the board down, handling is excellent.
TRAILERING
The total towing weight can vary considerably, depending
on model and options, and can be determined exactly by
using a weighbridge. Check that the vehicle is approved and
equipped as recommended by its manufacturer for towing
this weight, and the capacity of the towing hitch is suitable.
While towing, watch for strong crosswinds. A Corsair is a
relatively light boat for towing, but it still has considerable
windage. For easy, stable towing, the trailer should be
balanced to have 5 to 10% of the total weight on the coupling
ball. This can be measured by a bathroom scale. If you find
‘fish tailing’ occurs, increase this weight. If necessary, a
simple change like shifting the gas tank or outboard forward
can make a considerable difference to trailer behavior.
Trailer lights are fitted either on special brackets or as a
separate light bar on the boat’s transom. They are thus
independent from the trailer, and the wiring never gets near
the water, considerably improving reliability. If separate, be
sure to fit the correct lights on the appropriate sides. The wire
should be run along the top of the boat, looped around the
Light bar being fitted on an F-28. Note vertical position of transom hung rudder blade for trailering
