The Sea Bright 38

by Reuel B. Parker

Sea Bright 38 Profile

The Sea Bright skiff is an American innovation that first appeared on the beaches of New Jersey in the early 19th century. Originally rowing and sailing skiffs, they were launched and retrieved between beach and breaking surf. The model proved to be one of the most seaworthy of all small craft, and it is still used today in life/rescue operations worldwide.

With the advent of the marine engine shortly after 1900, the skiffs grew in size and diversified in function, being used for commercial fishing, rum-running, and eventually for pleasure. The hollow “box keel,” peculiar to the Sea Bright type, allowed engine installation to be horizontal, promoting a low center of gravity and no power loss due to down angle in the drivetrain.

Optimaster 310: A Sail-Training Dinghy for Adults

by Eduardo Marcondes

Optimaster 310I designed the Optimaster after taking my 10-year-old daughter to sailing lessons at a yacht club in Brasilia, Brazil. Not surprisingly, her training boat was a ubiquitous Optimist pram. Some other parents and I were on the pier watching the children have fun learning to sail, and we wanted to try it. The instructor said we would have to take classes as a group on a bigger boat, because the Optimist was only for children. So we did, but it hasn’t been the same experience our children had, each in their own boat with the freedom to come and go, risk capsizing, and be responsible for recovery.

Albatross Marine’s Sea Van:
A Small Passenger Cat

ASV 1100 Exteriorby Albert Nazarov

In many coastal cities increasingly dense automobile traffic has spurred the demand for water transportation and created a need for new high-speed passenger vessels. And, in countries like Thailand, Malaysia, the Maldives, and Indonesia, many island resorts require water transport from the mainland. Those vessels should match the luxury of the resorts they serve, without requiring large investments. A water taxi or small passenger craft on a catamaran platform is a possible solution that our Thailand-based design office of Albatross Marine Design is pursuing. Our office has an extensive record developing 19.6′–78.7′ (6m–24m) catamarans, and these boats are currently in service as passenger craft, dive boats, and pleasure boats in many locations. In designing the new Sea Van, or ASV1100, a modestly proportioned (36.25′/11.05m) passenger catamaran, we tried to meet requirements for stylish, functional, and safe craft to bring high-speed transportation to a new level.
