Dolphin 17

The Dolphin 17 is an American trailerable sailboat that was designed by Glenn Corcorran and Murray Corcorran and first built in 1970.

Production
The design was initially built by Universal Plastic Products, first in Houston, Texas, United States and later in Coffeyville, Kansas when the company relocated there. It was then built by Silverline Boats in Moorhead, Minnesota, although that company closed in 1980 and the design is now out of production. A total of 740 examples of the type were completed.

Design
The Dolphin 17 is a recreational sailboat, built predominantly of fiberglass, with wood trim. It has a masthead sloop rig, including a backstay, aluminum spars, a spooned raked stem, a vertical transom, a transom-hung, kick-up fiberglass rudder controlled by a tiller with an extension and a retractable fiberglass centerboard. Unusually, the jib is not mounted to the forestay.

The boat has a draft of 4.25 ft with the centerboard extended and 1.08 ft with it retracted, allowing beaching or ground transportation on a trailer or car roof rack.

For sailing the design is equipped with a self-bailing cockpit, a mainsheet traveler and a boom vang. There are three stowage lockers fitted, two on either side and one in the stern of the boat.

The design has a Portsmouth Yardstick racing average handicap of 97.8 and is normally raced with a crew of two sailors.

Operational history
In a 1994 review Richard Sherwood wrote, "in addition to the open design, there is a cabin model available. As might be expected, it is slightly heavier and has a reduced sail area. Capacity in either model is six adults; the cabin model sleeps two. The Dolphin 17 has covered storage on both sides of the mast, as well as aft storage."
