Re: difficulty raising mainsail the last few feet

As mentioned, it may be that the leech is getting taut before the luff.

Before you ascend the mast, try raising the aft end of the boom a foot or two with your topping lift. If the the luff then gets fully taut, you know that it's a geometry thing and not a mechanical thing.

(OK -- just read the OP more closely; seems like you've already done this step. Oops!)

Re: difficulty raising mainsail the last few feet

One other thing I do with my main is to hoist it up as far as it goes, then use the cunningham to get full tension on the luff. I cannot tenstion from the main halyard alone to get proper tensioin, not really sure why, maybe the plastic slides get cocked and jam on the mast track. In any case, the cunningham works well and gets good tension on the lower part of the sail. Although it sounds like your sail is jamming well before you could downhaul with a cunningham to tension.

Check the turning block, at the base of the mast, that leads the halyard back to the cockpit. Mine got twisted, and just needed to be turned straight.

Re: difficulty raising mainsail the last few feet

GREETINGS EARTHLINGS; OK back to basics, is the sail correct for the boat, is the boom set correctly on the mast is there a slide on the boom up and down the mast ? is cunningham, boom vang, boom down haul, reefing lines, all slack ? has the sail snaged the reefing horn on the way up? have you sent up a single slide on a down haul up to the top have you use any washing up liquid as a lube ? is the bolt rope in good contition ? All that will keep you busy for a day enjoy GO SAFE

Re: difficulty raising mainsail the last few feet

I had difficulty with the last 10 feet or so of the main, checked that everything was OK and it was still almost at the point of maxing out the two speed winch to get it all the way up. After eliminating everything else I concluded that it was a problem with the winch itself. A couple of new bearings and lube and the sail goes up fairly easily now, for a heavy three reef offshore main.

Re: difficulty raising mainsail the last few feet

A really quick fix is to place a birthday candle in between the first couple of slugs as you feed it in the track.do this on a warm day and the candle will lubricate alot of track and the string will blow away

Re: difficulty raising mainsail the last few feet

1. make sure mainsheet, vang, cunningham, etc. are free to run.
2. clean the track and apply lube (McLube or candle wax rubbed on)
3. replace 'thinned out' slugs / clean the 'slugs'
3a. after clean and lubed track, with binoculars, watch for slugs 'toggling' in the track - change the slug binding / slug shackle or slug binding tape or twine to let the slug become 'more free' in the track
4. If the halyard eye splice has become 'fatter' than original, with the binoculars, watch to see if the 'fattened' eyesplice is 'jamming' in the sheeve at the top of the mast. Put a mark AT the non-spliced part of 'working end' of the halyard, raise the halyard with 'rope' attached instead of sail and WATCH to see if the splice is or isnt 'jamming' in the top sheeve. If so, replace the halyard (next to impossible to make a new eyesplice in an 'old' line) and use smaller diameter but 'stronger' high tech halyard line.
5. Replace the 2 slugs that are attached to the 'headboard' with teflon coated, extra long, 'clew slugs'. If only 1 slug mounted to the headboard, add an additional slug ... as far away from the original slug as possible.
6. once the track is cleaned and dry-lubed and free of oxidation, bird ****, and mud daubers ... carve a paraffin candle to the exact diameter of the slug and put it between the top-two slugs in the track ... will lube the track every time you raise the sail.
7. If the track is worn out and corroded beyond the depth of the anodizing, and has LOTS of surface corrosion, roughness, etc., then consider an external StrongTrack system (VERY expensive).

Re: difficulty raising mainsail the last few feet

Increased halyard diameter due to splice bury? If it's a rope halyard of course...
