today, while taking apart a prindle 18 I bought recently; to inspect the bottom of the hulls, I found a very unpleasent suprise, I found two very large areas of delam. I'll attach photos of the area's.
http://thebeachcats.com/pictures/?g2_itemId=107966 all the area's with spots are very bad area's of delam, and the outline is area's that are pretty soft in general. the one spot with tape on the front part is where the glass is almost bent in.
My first question is, what should my next step be with the boat?
I'd like to repair it at pretty much whatever extent if possible. But it seems doing epoxy injections to that entire area would probably add a bit of weight. Could I just inject epoxy into the area's that are very bad and maybe just add a layer of fiberglass over the entire area?
I'm just looking into what I should do, I'm still pretty new when it comes to restoring boats. any help would be awesome, Logan.

IMHO adding weight by epoxy due to epoxy injection is not a concern. The few ounce to pounds that could possibly be injected will never be noticed in the way the boat sails. Make it strong and get it back on the water. Adding a layer of glass to the on the other hand is tough. It will be tough to get right and if not done carefully will be very apparent and could slow the boat by changing the hull shape. -

Thanks for the reply
So just to the injection to both the entire areas? Even the large ones?
The other thing I was looking at doing was cutting away the soft spots that are large, putting some expanding foam there, and shaping that to the right shape, then putting a layer of glass over that. I'm not to concered with how appealing it looks, just how solid it looks. It's eventually probably getting a new gel coat or bright sides eventually anyways.

Logan, do not go with the expanding foam method, bad choice, read this and go with the injection method, really simple, just get your working surface level and inject.

Remember this, lay-up is like a sandwich, fiberglass (inner skin), foam core (center), fiberglass (outer skin), delam occurs with the inner skin pulling away from the foam core, you need to fill the void.

Well, the soft spot issue is fixed, but somewhere in the process another small goof came up. Somehow I got a nice puncture through the first layer of fiberglass on one of my hulls. The inside layer of the glass is all in tack, just a tear through the outer skin. Can be seen here http://tampa.craigslist.org/psc/boa/4459483813.html
Since it's only through the outter skin do I need to reglass over it, as in put a piece of glass over it? Or could it just be a matter of marine texing over it? Just not really sure what direction to go with it and looking for some advice, thanks

Had a identical spot on my P18-2, bumped into a road trailer. Made the gelcoat around the spot very rough with a multi-tool, to the extend you could almost see the fiberglas. Then filled it with a mixture of polyester-resin and fiberglas, no mat, just fiber. Sanded the spot till it was fair. Finished it with two layers of topcoat (gelcoat) which I
,again , sanded till it was fair. Its holding very well for the past two years. Sorry no pics of the repair.
My neighboring boat-builder recommended polyester-resin instead of epoxy, since a Prindle is build in polyester.
Regards, André
