Simple surf superjet

[yamanube]

This has been constantly evolving since moving down to Florida last year.
Started off as a clean, mostly stock 98 with an R&D pipe and some simple parts.
I stuck the hodge podge 760 that was in it so I built and ported a fresh 61x 760 and put in a B pipe. It has just been slowly progressing bit by bit from there.
Has a Wamilton glass hood
KP pole with WDK steering
CarterB bolt on sponsons
Home ported 760 with zeeltronic
The usual other stuff.

Pictures ended up out of chronological order.
Tonight I wrapped up a super quick and cheap hull chop and color change. Just need to flip it over and put the tubbies back on and the pipe in.

I cut the back of the hull open, dug the foam out about 3/4" with chamfered edges that are about 1" deep. I poured in a layer of epoxy resin and milled fibers to fill all the gaps in the foam and level it out then a mix of 9oz S glass and 12oz biax in random sizes and orientations about 3 layers of each. Then poured in resin with 1/2" chopped strand mix to fill the bulk of it and let cure and later skimmed with epoxy and micro balloons. I typically never try this hard on body work but it turned out pretty nice. I kept it as dirty as possible by spraying appliance epoxy over the blue rattle can.

Had my son paint the hood today and I matched my sponsons to the bottom deck.

Am I understanding this right, you have something like 3/4-1" thickness that is basically all thickened epoxy?

It's realistically more like 1/2"-3/4" of thickened epoxy (the majority of which is chopped strand) with 3 layers of 12oz biax and 3 layers of 9oz S glass suspended in the middle.

Ride report: it's wonderful. That is all.

Okay, that's not all. I have previously shortened two superjets -4" with a straight up 90° chop and an XFT that was -5" angle cut like this one but the topdeck and rear rail was removed.
This is a sweet spot between the two, my XFT was a bit to nose happy and a little difficult to recover from airs.
The other superjets had full rear rails that felt like brakes, the angled rear sees to have a softer feel when sliding.
Went out for a fun session in Daytona today (2'-3') and the hull was much better all around. The steering is noticeably quicker, I could get in the back seat to keep it from stuffing the nose and it still seemed pretty good at speed. Much more playful all around.

Was this a 4” chop aswell, don’t see a measurement listed specifically of how far you went.

It ended up like 4.5" at the bottom edge, I didn't have the hull at exactly the right angle when filling it in so I had to grind a small lip off.
I was going to do 4" but that left a bit too much room between the rear rideplate insert and my cut edge that would have taken a lot of resin to fill.

Did you relocate the ride plate inserts and use a SN plate?

Yep, just re-used the stock inserts. They had a cavity around them so the same chopped strand and resin that leveled everything off is what holds them in and it's all one piece essentially.
