series of closely spaced rollers to spread support to several of the boats
cross ribs. Single rollers between cross ribs must be avoided. Roller heights
must be adjusted so that boat weight is evenly distributed on them. One
roller set higher than the rest can cause a "hook" in the boat bottom.
Side supports should run parallel to the keel and support the aft 1/3 of the
hull, extending beyond the transom. If center supports are used, they
should not exert any great pressure on the hull where flexing may take
place. Side supports need only be tight enough to keep the boat centered.
Before towing your boat, close and secure all hatches, doors, and port
lights; store equipment securely; take down and carefully secure all canvas.
Tops, side curtains, and aft curtains can be damaged while towing in the
raised position. When rounding turns on highways or streets, do not cut
corners. Also, go slow over railroad tracks.
Tie-Downs
Insuring that your boat is held securely in place on the trailer's hull supports,
especially when underway, is extremely important. If it is not firmly and
properly secured, your boat can be damaged as it bounces against the hull
supports -or it may slide or falloff the trailer while being towed. Depending
upon your boat model, all the necessary tie-downs for holding boats on
trailers may not be provided by the trailer manufacturer. Regardless of your
trailer's make or model, there are two key areas to consider:
1. Bow Tie-Downs: A bow stop to hold the front of your boat in place is
located on the winch stand. It should be positioned so that the winch line
pulls the boat bow forward against the bow stop. A separate tie-down
should then be attached to hold the boat down to the trailer (see
illustration). Besides keeping your boat from sliding off to the rear if the
winch releases, in conjunction with the winch stand it must keep the boat
on the trailer during quick stops or minor collisions. Be certain that the lines
do not pass over any edge that will cause chafing.
2. Rear Tie-Downs: As noted previously, it is very important to be sure that
the transom of your boat is resting fully and securely on the supports
provided at the rear end of the trailer, and that it remains in place when
parked or underway. Special rear tie-downs are available for this purpose.
Check often to be sure the rear tie-downs are securely locked in place and
that they are tight enough to prevent any movement of the boat. Check by
rocking the boat on the trailer. If it does not remain firmly in place on the
supports, tie-downs should be tightened or re-rigged. The strength of rear
tie-downs should at least equal the trailer's empty weight.
Make sure that the boat is securely fastened to prevent movement between
boat and trailer. Do not overload your trailer by putting camping gear or other
heavy equipment in the boat.
