From the yard original brochure:

Endeavour Yacht Corporation was founded in 1974 by John Brooks and Rob Valdes in Largo, Florida. John Brooks was born in 1934 in New York City and got started in the business first with Charlie Morgan, and later with Ted Irwin, Vince Lazzara (an early owner of Columbia Yachts), and sons Brad and Dick at Gulfstar. Rob Valdes was the younger brother of Dick Valdes, cofounder of Columbia and then later Lancer Yachts. Rob began his career at Columbia, and persuaded by Vince Lazzara, then joined Gulfstar. It was at Gulfstar where Rob met John Brooks.
The Endeavour yachts joinery in teak cabinet work is exceptional. Our satin varnish interior, unique and comfortable cockpit, combine to make living aboard for a day, or a year, a happy and comfortable experience.
We at Endeavour are very proud of this effort. The boat is successful and very complete. It may just be the one quality sailboat that is still affordable.

There is an owner website for more info and an excellent description of the boat specific building.
