Ok guys, update time.

I picked up two more ski's for a sweet deal. Both 1992 models. One is an xp and the other is an spi.
Both skis run! One hull has a couple of deeper gouges but would still work, but I would want to fix it first for peace of mind. I am going to use the older hull I already have and the best of the two newer ones.

I also picked up another boat. It is a 14' richline, almost 5 feet wide and 20 inches deep. It is a pretty solid boat, and it even came with a trailer. I traded some pork for it. I plan on putting on epf the ski's in that one too and then maybe selling it to get some cash. We will see what happens.

I have the older ski hull cut down to size, but I need some opinions on where to vut the front off.

My first and preferred method is to use 6 feet of the ski hull and keep some of the front curve to bring the ski hull back up inside the boat. This will require some fidgiting, but should work ok. I like that the two hulls will be parallel.

The other option is to cut the hull at 4 feet and have it tipped at an angle to get the front end up inside the boat. It would work well, but I don't like the idea of having the two hulls at different angles in the water. It may not ride or behave right.

What are your thoughts? I am trying to make headway on this, and will be bolting something into something else very soon if I can figure this out.

I would go with the 6 foot, using the keel's curve to act as a spoon.

Use some of tghe hull material you cut out to make a filler panel.

Make it double thickness if you can.

I did the 4 foot method you described, it cavitated terribly.

Good luck!

Iam glad you said what you did, because I have been weighing both options all day and went with the 6 foot method. I am almost done cutting it out and will test fit tonight.
