I am loving the sc17.
So much that it gets sailed about 3-4 times a week.
yesterday i noticed damage on my portside transom.
I have heard horror stories of supercats with ripped out transoms.
What is the best way to tackle this problem?
Are there any backing plates, if yes are they attached to the hull in some way?

Re: Transom
If you look at my Refurbishing a Supercat 20 post you will see some pics of what it looks like inside.
If I were you I would take off the aluminum (hoping the aluminum backing plate doesn't fall off inside), grind off the paint and through the crack and put several layers across the whole upper back and around the edges. Re-drill the holes and paint it up and it should work fine. If the backing plate is loose keep one bolt in to hold it.
You could cut an access hole and beef it up inside too.

Re: Transom
Kevin's suggestions are good ones. Typically a repair from the inside ends up being stronger, but it will still require some level of repair to the outside also.
I would also suggest getting rid of the stainless gudgeon pins and replacing them with the black plastic ones we supply now. The stainless pins have a nasty habit of getting corroded in the cast rudder head and gudgeon's, preventing them from pivoting and even ruining the casting.

Re: Transom
Thanks for the replies.
I will do the repairs this winter, document it as well.
The plastic ones, are they larger? I have about 3 mm wiggle on the gudgeons.
Is there something else i can do about that?
By the way, anybody ever trapezed from the forward tip of the hull on a supercat?
It was cool to try, close hauled the leeward hull disappeared. at least 15cm under water. But it kept on sailing.

Re: Transom
I'm lucky enough to have a lathe and a mill. So I might bore out the holes and turn a piece a plastic to fit.
I have buried my bows. One time I was trapping and my friend was sailing it. He buried the bow, the brakes came on and I went swinging all the way around in the front of the bridal stays still stuck in the trap. Then the boat took off again while I was bouncing up and down in the water with no input at all to my fate. All I could do was get an occasional glance at my friend with his mouth wide open and wondering when he would turn into the wind. It was all pretty funny, at least after I popped out of the harness. Wish my bows were 2 feet longer.
