A Searunner 40 under sail

John Marples and Jim Brown have produced designs of successful sail and power craft for over 40 years using conventional materials and cutting-edge design to produce vessels that are stronger, more seaworthy, and more practical to build than ever before. Ease of handling, longevity, utility, operating cost, investment value, and speed are all essential components of what we term Total Performance in pleasure or commercial craft design.

These vessel designs are straight-forward, easy to build, wood and epoxy, using various construction methods for multihulls and dinghies from 7 to 64 feet. Our portfolio of designs includes trimarans and catamarans, sail and power, pleasure and USCG certified commercial vessels.

The site is under construction at the moment but soon you\'ll be able to view the Design Portfolio of our entire design line or purchase Study Plans for individual vessels from this web site. Call today for a personal consultation. We look forward to assisting you with your boatbuilding project. In addition to plans, we offer design consultation and USCG certification services for wood and fiberglass vessels, power or sail, with multihulls of all types, as a specialty.

Over the last 20 years, John has helped the owners of 30 multihulled vessels certify their boats with the USCG to carry passengers for hire. These vessels,ranging from 32\' to 64\' long, were approved to carry between 16 and 149 passengers. Some owners were building a new boat and called John before they started construction. John reviewed their plans and then modified them to include the necessary components required for certification. Once John submitted the plans and the USCG approved them, he continued working as a liaison between the owner, builder, and Coast Guard until the finished boat passed its Coast Guard inspection. Other owners had an existing boat that required modification for CG approval. Again, John made the necessary design changes and submitted them for approval. He worked with the owner and builder to help minimize the cost of making structural changes to the vessel. John worked as liaison throughout the reconstruction until the certification process was complete. You can find out more about USCG certification elsewhere on our website.
