Re: SC 17 Asymmetric Weather / Lee Helm
Hello, Your experience with weather helm on one tack and lee helm on the other is not all that uncommon. You are looking at all the right things and I suspect you will find the problem with one of two things. Either one or both of your rudders are not symmetrical and the pivot point is not correct a...

Re: Super Cat 19 Parts compatibility
The Standard 19 and the Supercat 17 both share the same mast length. The main difference between the two is that the SC19 mast had spreaders, the SC17 did not.

Re: Super Cat 19 Parts compatibility
Congratulations on your purchase of the SuperCat 19. The parts you mentioned are unique to the SuperCat product line, however many of them are common with other model sizes. Rudders are common with the entire product line, daggerboards were common between the 20 and 19. The mast profile was common a...

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
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...

Kevin,
Yes, roll from the top down. Typically folding at the second batten thou. Usually the second batten in the main as well.

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...
