I noticed an old thread and wanted to comment..
I built a roberts 370 design and have never 'asked Bruce' but instead used the grace of local boatbuilding shops and suppliers and also fiberglass experts in the aviation industry for technical support..found used books like Ferenc Mate 'from a bare hull' and Vaits' One off boatbuilding in fiberglass which are far more helpful and sound than Roberts work..
From my background in basic physics and aviation work I immediately saw the engineering in his designs was intuitive and weak, not structurally sound..reinforcemnts not a the stress points and his laminate schedules are wasteful and heavy. Not engineered..
Until I asked his advice I suspected he did have qualifications as an NA and then with simple questions about speed and hull shape and boat performance, the only replies I got from him were demands for photos, to puff his promotional materals and then, "no comment."
There is a wealth of expertise and information here, Id just say if you have his plans, get LOCAL help to modify and tweak them to your purposes, or stdy and do it yourself..but dont "ask bruce" because its a waste of time.
His designs seem to be things you could find in any book of boat plans available in a used book store or taken from any proven, popular and tested classic design..Hes a marketer. His loyalty to his customers extends to cashing their checks..Dont ask me about Bruce!
He has quite a section on his website about stolen plans and detractors which seems to show he isnt held in high regard either business wise or as a designer. Boatbuilder Homebuilders, be advised...but nothing against his boats. Theyre beamy, stout and conservative shapes..stable. Some perform wonderfully others less, just depending on the quality of construction..which with amateur builders varies from marginal to superlative, of course..
Like one author clarifies, a good boat is a thousand jobs, done well. (more like a hundred thousand jobs)
