"I've contacted them by email from their website and never had a response. I think they are bankrupt, out of business or just plain don't need any more sales. Forget them!."

See what happens when you quit taking your meds?

I have a 17 foot Supercat that ARC supports with any part or information I have asked for...technical or general. As an owner I can go on their forum, ask a question and get answers from Matt at the factory. In most cases, Bill Roberts (the designer/engineer) will shed even more light on the solutions available.

I might add that my boat is a 1992 and they still strongly support it…to the point that Bill Roberts personally invited my wife and I to his home to help explain the proper set up of the self taking jib. (which had been rigged wrong by earlier owners) and give sailing tips particular to my boat. Again this is a boat I bought used from a private owner, they made no money, yet bent over backwards to help me straighten out a number of rigging problems the previous owners had caused.

If you make serious inquires, they will respond promptly.
If you approached them with the same tact that you exhibited in your prior statement (as quoted above) you should not be surprised that you didn't get a response.

Regards,
Bob
