Opinion of Bruce Roberts 29 Sailing Qualities?

[mischief]

Hi everybody,
I was wondering if anyone has some experience with the Bruce Roberts 29? click here If one one was fitted out in full cruise trim weighing in at 6.2 ton and empty tanks would 2 tons of ballast be enough (seems light to me)? Using the full keel option built in single skin fiberglass with a traditional stern, do you think they would make a good seaworthy vessel? Note the 6.2ton weight is acurately calculated and verified but does not include weight in tanks or stores.

Obgective would be coastal cruising and making shorter passages but in some rough areas.

Opinons greatly apreciated.

BTW I am not interested in debating the pros and cons of building, having built, or how someone else may or may not have buit one. Sorry I just want to make sure that the thread does not degenerate off topic and that the opinions of the design itself are adressed.
