Will,

I am sorry, but I have to agree with John. Sandwich construction buildt light enough for a catamaran need to be treated carefully. Hitting rocks or letting waves and wind pound the boat on rock or concrete will ruin the laminate and make repairs neccesary. You can park the boat on a sandy beach, with care, but the boat should go directly from the water to the beachwheels.

A 5 - 7 lbs difference between hulls isn't that much. It can be caused by a lot of things. I would not worry overly about it knowing that advanced sandwich construction need aircraft grade quality systems to produce identical parts. We would not be able to pay for aircraft grade quality tough..

If I was you, I would have the boat repaired (not impossible at all, just need to let it dry out) and moved on. I am sorry to hear your story but hope you fix the boat and continue sailing it.
