So, it appears the prior owner, or some prior owner, did some creative bodywork on the starboard hull and bondoed it up. After we pulled the boat out of the water, the starboard hull was leaking water. Found this on the bottom:

I'm pretty sure we didn't hit anything. Conditions were very light. I think the bondo just failed, either on the trailer or while in the water. We got gallons and gallons out of this hull.

The cat comes apart tomorrow, so I can flip it upside down and fix it properly. Boy am I glad I didn't glue all the trampoline frame together.

If this hull is trashed, I still have the starboard hull from the original boat.

A GREAT example of why "no bondo" on boats. Th bummer is, there's perfectly acceptable alternatives readily available, like Dynaglass; most manufacturers will actually list whether or not the product is acceptable for water immersion. Bondo specifically states that it is not; apparently hydrophilic.

Bummer you had to discover it that way, but looks like it might be easy enough to repair, but regular old fiberglass and compatible fillers like micro balloons or colloidal silica would be my go-to. Looks painted, so even easier in the end, unless you do a 100% bottom job...yuck.

Hey Chuck,
This hull weighs 128 lbs. I am going to fix up the starboard 85 lb hull from our first H16 and use it instead, as discussed here:

I had the exact same issue when I first brought my N5.7 home. Someone stuffed a plastic pop lid along with some goop into a finger sized hole.
Light pressurization & soapy water found it.
I ground out the damage, made a “taco” out of a few layers of cloth,(with a bit of line so I could insert it into the hull then pull flush).
