Shiping to Lithuania would definately kill the deal, but I don't mind getting my hands dirty.

Few questions keeps me from starting this project.
1. Hulls are made of two halves joined on the centerline. So to install this bulkhead i would have to cut a hole in a foredeck. Has anybody done similar holes? What is the technique used to do it?

2. Where and what size should this bulkhead be?
