We stepped the mast for the first time today. My new bridles were not quite right. I think it's possible I didn't explain my rig well enough to Tom Haberman at Aquarius. I've got an inquiry into him. Still, it was cool.

Yeah, that's raked way back and I see the shroud extenders are hanging.

Is that a gin pole or spin sprit?

No gin pole, so I'm not sure. I've learned the H16 but I have very little knowledge of the Supercat.

Do the shroud extenders make these things unnecessary?

Not sure I understand the question, so forgive me if butting in here I get this wrong. You need the chain plate quick disconnects to pop open the connection, allowing the shrouds to lengthen, thereby allowing the boat to be righted much easier. Mine has a Hyfield lever setup I installed, copying Aquarius' later designs. I think a bunch of cats might use them, don't know which. Theoretically, when you pull the pin, the shroud lengthens allowing the high hull to rotate to or past vertical allowing your weight to finish the job. As a side benefit, with the levers,no can very easily change the tension on my rig and/or adjust the rake.

Neither
a gin pole typically isn't a fixed spar
a bow sprit would need to extend past the bows

I have a friend who has the same gear on his cat - has a front tramp too
I believe it is just to make the bows and forestay more rigid but not 100% certain that is it's only purpose

That spar(s) is to allow for a larger jib to be fixed at a lower point. You can see the compression post inline with the forestay. My buddy had one on his modified P19. Its an easy way to add a lot of sail up front, but also blocks your view.

Sorry - looking closer, it looks like your picture does show levers under the blue tape. I'd keep the setup that way and see if you can't remove a little rake somehow.

"You need the chain plate quick disconnects to pop open the connection, allowing the shrouds to lengthen, thereby allowing the boat to be righted much easier.".....but your missing the wire and spring that slips when using the Hyfield lever...........to right your boat.....

It is possible that the previous owner was using those levers to tension the rig, although high rig tension should not be necessary.
the boat was designed for 5 degrees mast rake. If you make the bridle wires too short you will need a bar between the hulls up forward. The stock length bridles and a stock length forestay is probably your best bet. You could sell those levers and save some weight. hope this helps.

I've been talking with Tom Haberman. The guy who used to own this was friends/neighbors with Bill Roberts. It appears there are ARC-17 mods done to it. So I think the stays are correct but the bridles and forestay/jib halyard are wrong. I've got to do some measurements for Tom. I'll let you guys know how it turns out.

This boat has been owned by Sikorsky people since the '80s. Sikorsky and P&W were part of the same corporation and they shared facilities in West Palm Beach, Florida. Bill worked at P&W.
