need to fix?

I have a '77 Hobie 16. The port hull has been repaired in front of the platform and is solid. The starboard hull has a very slight amount of give in front of the platform. To this point, I haven't worried much about it.

Beneath the two posts, under the platform, is another story. It is much more flexy, on the port hull in particular and starboard a little. I've read that this isn't as much of a stress point as forward of the posts. I'm just starting to trap out and figured as long as I stand only on the platform and not the hulls I should be fine.

Do I need to be doing hull repairs now?

Yes. If you don't it will just get worse.

So I guess I should do the entire hull then and not just concentrate on the part in front of the platform?

was the photo supposed to tell me something?

Any delamination is a structural issue that can cause the hull to fail. Yes, do the repairs or replace the hulls.

Maybe Matt B meant this link?

Certainly was a pretty picture of a double trapped H16 though!

No, just not paying attention. Photo went into the "mast rake" thread.

Matt, thanks for the input. The repair doesn't sound too complicated. I'm curious as to how much Git Rot I'll actually need. It looks like the large bottle is 32 oz. Is that enough? How thick is the foam layer between the fiberglass layers? Thanks!

BTW, great photo, just wondering if it was a mistake - very inspiring for this aspiring trapeze artist!

I was looking at the diagram matt linked to and it advises putting a big hole in the middle and smaller breather holes at the perimeter. I've also heard that you should start at one end of the delam with holes and move to the other end as the first holes fill up. Do both methods work equally well?

Also, is it worth it to buy Git-Rot if I have access to some leftover West System epoxy and filler?

thanks

The delam system I have quoted does not reference large areas of delamination. For a large area you would have to do small areas at a time.

How much resin? If your are careful... less. If you force too much in, you force the layers apart and consume too much and end up with a heavy boat.
