I'll nit-pick just a little and then shut up, I've stated my opinion on the boat.
Ted Hood was not a naval architect, he had no training in the subject. Dieter Empacher, who worked for Ted and did all his early design work was the naval architect.
Besides that sidetrack into the wilds....Surely we can agree that the Gulfstar 53 was one thing when designed 40 years ago, and this highly modified version is something very different today.
Please realize there are many folks looking at this forum with no experience of boats at all. You realize there may be a stability issue with this boat, but many would not. It is to those folks I am speaking.
Yesterday I had a PM from another member here who just bought a boat and was wondering about her stability. He could find no information publicly available on the stability of this popular production boat. As the boat he bought is unmodified and from a well respected designer (who has his name on the plans), I was able to reassure this owner that his boat will be fine and take him anywhere safely.
I feel strongly that stability of pleasure boats is an issue that is too often swept under the rug and ignored. I would like to encourage understanding of the issue. Yelling fire in a crowded theater is irresponsible, but it's also irresponsible not pointing out that a child playing in the street is unsafe. (IMO)
