Several Ways to Tackle this Pride
I have a 2004 387 that has the Dodger, Bimini, and connector that came with it from the factory in Florida.
It has an tag sewn on it with the name of the company and a phone number. I can pick up that number tomorrow and e-mail it to you and I would suggest that you could call them and give them the make, model and year of manufacture and see if they have what you desire.
You could go to the Sailrite website and hunt around and see if they have a set of plans for one and if you are talented enough make it.
You could see if you can locate someone in your locality that would make one for you. Figure about $100 per foot to get a canvas or sail maker to do it for you. This is based upon an assumption that you have the Stainless Steel already and they can use that. Also, are the snaps in place to fasten it to?
You could contact the manufacturer of your boat and ask them who made the canvas for them back in 1993.
You could contact the Catalina Owners Association and ask them.
Good luck, Tom
