Only two possibilites, no, make that three. 1. There is significant growth on the board and/or in the trunk that's causing the board to hang up. 2. Don't know if it's possible with the
fiberglass board but the board could be bent from a grounding. 3. The pendant is hanging up in the tube or friction in the
winch.
Had my board hangup after more than a year of disuse because of
marine growth. Sailed the boat with a some slack in the pennant and it eventually broke free. Cycling the board up and down several times after it came loose cleaned the critters that it's worked fine ever since. Never ever let the board pennant run free when lowering the board. The board will hyper extend crashing into the front of the well denting the board and possible fatal damage to the pin.
Switched from a wire pennant to a
Dyneema one. The length of the splice fattened up the line so it jams in the turning block in the
bilge and leaves an inch or so of the board's tip hanging below the
keel. Before I realized this was happening, yanked pretty hard on the pennant line in the
cockpit and the splice section stuck a bit in the turning block. Did this when I was hauled so just jiggled the board a bit and it came free. Now just pull up the board till I get resistance and stop. If you have a wire pennant and it's getting worn or broken strands, it could also be hanging up in the tubing run from the
winch to the
keel. Occasionally have a little hesitation in the board initially starting down that's been going for the 10 years I've owned the boat. Think that may be some initial friction in the winch but it happens very infrequently and has never hung up. If you want to change the pennant, use the old one as a messenger to pull the new one through. Piece of cake to do and could even be done in the
water. If I ever had to replace the
Dyneema line might just run the line through the hole in the board,
knot and stitch it to get away from the fat line caused by the splice.
Don't know if it's possible to bend the board from grounding, I haven't been able to do it. that could cause the board to hang up. Got the board hung up in my old
Morgan C/B boat sailing in the Chesapeake after a grounding. Turned out to be small pebbles stuck between the board and trunk. A little
work with a screw driver knocked them out and board worked fine after.
