1st sail of the season a couple of weeks ago..... leeward shrouds so saggy as to be dangerous. backstay ditto.
Deck stepped mast.
2 sets of aft swept spreaders.
cap and intermediate shrouds
fore and aft stays, (to just below 1st spreaders)
Roller reefing on forestay
Backstay
Roller reefing main
tightened caps and intermediates very hand tight. Then tightened them again 2 turns when they were leeward shrouds, so now reasonably tight.
all seems fine.
Thursday and Friday, roller reefing main refuses to roll out easily.... bunches up in the groove, and the bunch tries to roll out as well as the leech, thus jamming.
Look up the mast today and it has a bend in it from about the first set of spreaders to the top. This means that the top of the furling gear is aft of the bottom of the furling gear, thus pressing the rolled up sail against the back of the mast, resulting in the problem.
The mast obviously needs to be straighter, so the furling gear lines up inside the mast without being pressed against the mast.
Selden manual says:
".......... check the mast’s fore-and-aft tuning.
The mast should have a slight forward bend at the
spreader area. Sight along the mast from deck level.
Adjust if necessary using the lower shrouds. "
It therefore looks like I loosen the forward lowers and tighten the aft lowers to straighten the mast.... does this sound right?
Cheers
