i just received the line sheaves for my mast overhaul (converting from the original wire-line rig to all line), they're made for 5/16" line but after receiving them i realize how small this is !!
is anyone really raising and tightening their mainsail with such a small line?

Both of the all rope halyards on our C-25 are 5/16" line. With today's line technology, anything bigger is overkill. Lot's of choices available.

i'm sure it's solid enough, it's just the size of it... i'm used to haul on those large lines, they have a nice grip but 5/16" looks like it will cut through my hands... :-O

Richard,

Our 1981 C25 did not come with halyard winches. We added a double rope clutch and #6 winch on the cabin top for tensioning.

Almost a must if you are serious about achieving good sail shape.

i have the winches on the mast and i use them but even with winches there is some hand pulling to be done, i use the winch only for the last stretch of pull on the sail ;-)

BTW, one of our heavy-duty racers here spliced two sizes of rope together for (I think) each of his halyards--I guess to reduce windage aloft...

I used 1/4" with no issue. The red line was my headsail.

My halyards are 5/16 and 1/4. They aren't comfortable, but they don't need frequent tweaking. I still have cam cleats (I have clutches that I haven't gotten around to installing yet) and I just run the line to the sheet winch to initially tension if I need to.. I don't think it would do for somebody more critical. Having a thicker and softer tail spliced on is a common solution. I splice a lot, but I think I would pay to have two different sizes of double braid or a small double braid to a large single braid done.

I have become very fond of Nova Tech XLE line, the Canadian version of Samson XLS. It's low strtetch, very supple unlike Sta-SetX which I'm using now, and very reasonably priced on Ebay. A 5/16ths line has plenty of strength to serve as halyards. If I was seriously concerned about weight aloft and an easy grip, and unconcerned about spending a lot on halyards, I would have a shop splice a good 3/8" double braid tail line together with 5-6 mm Amsteel line.

http://www.ebay.com/itm/NovaTech-XLE-sheet-halyard-Line-5-16-x-100-white-Red-/360382418414?pt=Boat_Parts_Accessories_Gear&vxp=mtr&hash=item53e8774dee

I'm sure that the folks who sell this line would consider adding a splice on a shorter length for a nominal fee. Halyards that run aft to the cockpit can be cut to: jib/78' and main/75'

The only issue I've experienced is difficulty with the jib halyard raising the sail. That halyard runs aft to the cockpit and it gets hard to raise the sail after it is about 2/3 of the way up. I must be getting tension at one of the turning blocks, because I don't have the problem if I stand at the mast pulling on the halyard. It may also be the stiffness of the Sta-SetX line.
