I have seen a few of them split open on the bottom without hitting anything as well as a bulkhead separate from the inside. So, there were/are some hull issues. I weighed all the boats at the F18 NA's in Galveston and the Nacra Infusions had the BIGGEST difference in weight between one manufacturer. One of them actually weighed 419 lbs.
