I can't speak to the way the sailboat would handle, but I can speak to the quality of product Chris Craft was producing in this era, and it was VERY HIGH QUALITY in every way.
In 1962 Chris Craft was acquired by NAFI (National Automotive Fibers, Inc) and two years later they were producing a sailboat and the now iconic 38' Chris Craft Commander. The Chris Craft Commander series was the real big impact into fiberglass for the company, and this cruiser line branched out into many different models, and Chris Craft was also producing sport boats and as you know, sailboats too.
The acquisition was the best thing that could have happened to the company. NAFI did their homework well, selected only the very best resin and glass, and developed a construction method that is now legendary. Even the small boats that were also produced by the newly formed Corsair Division at Cortland New York (same time frame) used the identical resin and glass, and method of heavy roving, etc.
Here are some thoughts, manufacturer's early scans, and some photos and diagrams of how Chris Craft designed these early boats.

Although these are not necessarily sailboat specific, it is an indication of the hull integrity the company was producing back in those days. In addition, here is a photo of a plug I recently cut out of a 20' fiberglass Sea Skiff, to install a transducer. This is from 1966. They don't build 20' boats like this any more.
Here is another thread about blisters on these early Chris Craft boats. Blisters, by the way, are hardly even talked about in these early boats. The quality is very impressive.
