Re: Backward-looking at the cable traveler

Revintage, The cable was 1/4" Diameter 1x19 SS. Not sure on the diameter of the sheaves off hand, but I believe they were 2" diameter. If I am not mistaken they were a standard catalog wirerope sheave with a plain bore, ie: no bearing. Or if there was a bearing it was just a plain bushing,...

Re: Backward-looking at the cable traveler

Revantage,
I would say you want to keep it to a minimum. On the old cable traveler, the slack was sufficient so that when under load the traveler car cleared the beam when near the ends. This meant that there was an inch or two of extra clearance when near the center of the beam.

Re: 19 wire traveler conversion

The Traveler track should be screw "Through" the beam and threaded into a 1/4" thick backer bar inside the beam. We used 1/4" thick x 1/2" wide 6061 aluminum flat bar for the backer. The other option is to put nuts on every screw, feasible but a little tricky as you get towa...

Use those too. Hang the board horizontal, trailing edge down.

Re: Daggerboard Screw

Drain plug :lol:

Seriously thou, the screw was used to hang the board during painting. When the paint is cured the hole is filled with 5200 and the screw is inserted.

Re: Downhaul Rigging

Robert, Keep in mind on the H18 w/ Comp tip and the A class the masts are quite bendy and the downhaul has a major effect on the sail shape and mast bend. The mast on the 22 is significantly stiffer and as a result, downhaul has a much smaller impact on mast bend and sail shape. If you put a large e...

Re: Downhaul Rigging

Hi Robert, All of the ARC-22's shipped with the standard 6:1 downhaul system & three grommets in the mainsail as illustrated in the link Ghamby shared. The way that you string it is by starting at the exit block / cleat on the starboard side, go up to the middle grommet in the mainsail. Next, yo...

Re: New SC17 owner

Hello Genofleet119, You are correct that there were two different forestay assemblies for the SC17. The standard forestay consisted of a pigtail at the top, a turning block for the jib halyard, the forestay, a chainplate, the wire jib halyard and the rope segment of the jib halyard. The roller furli...

Re: SuperCat 17 Hulls Leaking

Drain plug leaks: First off it doesn't look like the housing is sealed to the hull. I would remove the drain plug housing, remove any old caulk and clean it up so you have a nice clean surface. I would then put a nice bead of 5200 around the back of the housing and in the screw holes, insert the hou...

Re: Rolling and storing a sail.

I guess we will have to agree to disagree..... All of the local guys we sail with roll them from the top-down, whether it's a 15, 17, 19, 22, Nacra 5.2, etc.... Been a very long time since I have seen someone roll them from the bottom up. Usually, if we see a sail rolled from the bottom up is becaus...

Re: Rolling and storing a sail.

Yes, but it's a 10x easier to hoist it when it's unrolled already so actually doesn't make much difference. Longevity wise we have found the sails rolled from the top are typically in better condition for much longer then if rolled from the bottom up.

Re: Batten knots

Kevin,
I usually tighten the main battens by pushing with my thumb until the batten (tubular) has a slight bend to it. Its tight enough to take the wrinkles out but not excessive.

The same thing for the gaff batten, however, if it isn't long enough that will make it more difficult :D
