Re: ARC21 Rigging question


I have a new to me ARC21. I am resurrecting a boat that has been sitting idle for 15+ years.
1. I don't seem to have any of the downhaul/cunningham gear. Is there an owners-manual or illustration somewhere? I would even be happy with a photo that someone may be able to share.

The mainsail ...

Re: Sail area of 19XL / 19X

From memory, I believe the 19X & XL both had a total sail area of 276sq feet.

Re: Supercat 17 fiberglass repair: Epoxy vs. Polyester Resin?

Hello,
I took a look at your photo, and I do not see any core material. What I do see is some resin/adhesive that was used to position the aluminum block before the laminate was built up over the back side of the aluminum.

Unfortunately, I am not aware of any STL models of the hull or saddle area.

Re: Supercat 17 fiberglass repair: Epoxy vs. Polyester Resin?

Hello,
Based on the photos I believe the boat is early 1980's, nothing newer then 1982.

Regarding your questions:

1) The hulls are symmetrical from the standpoint of shape, so yes you could use one hull to make a saddle mold for the other hill. Structurally the hulls are not symmetrical so to ...

Re: Supercat 17 fiberglass repair: Epoxy vs. Polyester Resin?

Hello,
The HIN was historically engraved into the transom or a metal plate on the transom. There was also a hull number molded into the hull, either on the transom on just adjacent to the beam saddle on the inside of the hull. If you share some pictures of the saddles, transoms, rudder assembly, etc ...

Re: New SuperCat 17 Owner

Hi Don,
I will try to address your question about sailing on the 17. The 17 really likes ot have the leeward hull driven bow down. Ideally , the leeward hull will be bow down with the water somewhere between the pinstripe and the deck, and the bottom of the stern will be well clear of the water. The ...

Re: Supercat 17 Mast Ball Popped Off

Hi Don,
I didn't recall the exact adhesive that has been used over the years, but I'm pretty sure it wasn't 5200. It was typically a two part epoxy that took about 24 hours to cure.

Make sure the inside of the ball and the post are clean and you can fully install the ball. Put a coating of the ...

Re: No steering with rudders up.

In shallow water I will kick up one rudder completely and the other rudder I'll kick up part of the way while holding the pull down rope to prevent it from coming up all the way. Once the rudder is part way up/down it will usually stay in that position.

That being said, it can be extremely ...

Re: Supercat 17 disassembly

Vic,
Hull weights varied over the years, and with age they tend to get heavier. That being said I would plan on something around 100 lbs, could be a little more or a little less.
There should not be any sealant between the beams and the hull saddle. People seemed to think it was needed, but we ...

Re: SC20 Beam Caps Cable Removal

Correct, the caps are not threaded. Corrosion is likely the issue since the rod is stainless and the cap is aluminum.

Re: SC20 Beam Caps Cable Removal

Kevin,
The threaded end is swaged onto the cable and is not removable. You should however be able to remove the nuts from the end of the threaded rod and remove the end caps, but the cable will remain captive inside the beam. Make sure to make note of how far onto the threaded rod the nuts are ...

Re: Outboard on ARC 21?

We have done it a few times on the 22. I searched the forums and didn't find any photos. If you contact Tom he will have some information on what was done in the past.
