Storage and Transportation
Dollies now available at www.boatdollydirect.com
The Butterfly may be stored on the beach or flat surface with no damage. If left on the beach with the mast stepped, the boat should be tied down to prevent being blown over in a storm, causing possible mast damage.
When the boat is subjected to the pounding and vibration of a trailer or car-top carriers, it should be supported as described below.
Typical bunks are 2 x 4~Rs carpeted and wedged 5/16" to conform to the contour of the hull. The bunks may be placed from 40" to 60" apart. It is important that the rear support be no farther aft than the footwell so that the weight is on the strongest portion of the hull where the footwell receives and distributes the load. The Butterfly may also be suspended by rope or strap slings. The slings should be placed in the same places shown for the bunks.
Pattern for strong, compact, two-piece mast and boom cradle, allowing clearance for rubber padding such as inner-tube material. Cut cradle out of 2" wood. The mast and booms may be tied down with rope, shock cord, or inner-tube strips.
The most important thing to remember when storing a boat in subfreezing temperatures is that water expands when it freezes, and a sizable quantity of water inside the boat could damage the structural members if left to freeze.
To properly prepare your boat:
1. Remove the drain plug from the transom and place it in your sail bag. Tip the hull by lifting the bow and at the same time roll the hull on one side to drain any water that might be trapped between the ribs in front of the footwell. Keeping the bow elevated, roll the hull back so that the transom is parallel to the ground. Any water accumulated will run out the drain hole.
2. Position the hull and/or cover to prevent ice buildup in the footwell. Storing the boat upside down is fine. In any case, support the hull off the ground or concrete, if only a few inches, to prevent ground or concrete acids from etching the finish on your boat. The supports should be placed under the back end of the footwell and anywhere from the front edge of the centerboard slot forward to the mast step. The same applies to boats that are hung from the garage ceiling. If the boat is left on a trailer the tie downs should be loosened so as not to exert undue pressure on the bottom for a long period of time.
3. Be sure drain holes are open in the mast base and all water is drained. If you store the mast outdoors, be sure to place the luff rope slot downward.This will prevent accumulation of water, snow, and ice which can and has ruined more than one mast.
