Welcome to FiberGlassics®

In July 1998 this site began an attempt to recognize the style and creativity of the original fiberglass boat designs from the 50's & 60's, plus capture the spirit of a time that has since past. This site honors the pioneering minds that conceived and created these beautiful, never to be made again, classic fiberglass boats. 

Within this site, you will find information on classic fiberglass boats. There are many sections. All libraries, pictures and information are FREE. Enjoy your time here.

How much horse power can my boat handle?

Well, it depends.

Back in the day, the Outboard Boating Club of America (OBC) developed a simple method to determine how much horsepower a boat can handle. Manufacturers had their own ideas of course.

Some boats may be able to handle more horsepower than OBC-certified or manufacturer's rating. Other boats may not. Above your maximum rating, a gain in top speed may be negated by poor high-speed handling. A heavier motor on the transom might also cause trim problems. Structural problems may become exacerbated.  A hook in the hull or weak transom might become outright dangerous at high speeds.

To aid in your selection of an outboard motor, please examine the following chart and table developed by OBC to help boat owners safely equip their outboard boats.
