I agree, but i could be totally in wrong. My 35JC w 320hp cat tops out at 18-20knts(20 with tide)
More realistically I could see 8-10cruise 14-15 top end maybe.
I've observed that if a Bruno happens to be solid glass, that is usually mentioned immediately. Unless the owner or broker is completely oblivious to the very coring problems that were the downfall of Bruno, why would that not be the first thing mentioned if it is solid?
