Re: 1974 Glastron V174 Bayflite
In the early 70s, Glastron was a very well respected manufacturer of small boats. In fact, earlier than that they designed the original deep vee hull and were widely copied. 1970s Glastrons were (in my opinion) very classy and pretty designs-- I own three of them.
However, I will not blow sunshine up your butt. These early Glastrons while pretty and fast were a little light in the topsides and the floors did tend to rot out quickly.
The avatar is a 1971 V153 with extensive hours on it. It was cruised new up the Hudson River to Montreal. Round trip about 900 miles. It has also circumnavigated manhattan Island and been out into the Long Island Sound as well as cruising the Chesapeake as far south as Annapolis.
The orange boat is a GT150 which is my resto project. Have you tried for info at classicglastron.com? I don't remember the numbers, But I believe all deep vee hulls ended with "3" Without a photo, I believe your Bayflite may be
the bowrider with the "Aqua-Lift-II" hull, a modified tri-hull. However, It will be listed in the model descriptions at the site.
Ah, See: In 5 minutes I went over to the site and identified your hull as the closed bow sterndrive, deep vee model. It was also offered in the outboard version, V173.
