    The New Era of Gasoline Fuel Installations – ABYC H-24 & H-25
    By Dave Gerr, from Information Provided by John Adey and the ABYC Technical Department

    After several years of discussion, investigation and review, the U.S. Environmental Protection Agency (EPA) has introduced completely new regulations governing fuel installations on boat with gasoline engines or equipment. Most of these new regulations have been implemented starting in 2009 and through 2011. (A few final aspects are scheduled for implementation in 2012.) New regulations and requirements mean added cost and complexity, but they are the law and must be followed fully.

    We'll review here what the new EPA regulations are and explain some of the practical approaches for implementing them. These regulations are now law under the Code of Federal Regulations, specifically 40 CFR Chapter 1060. They will affect the way you design, build, repair or inspect gasoline boats from now on.

    This article is "MUST READING" for everyone involved in design, building and repair of boats and yachts.

    Four From Westlawn Contribute Notable Designs To Woodenboat's Design Challenge III

    The editors of WoodenBoat and its sister publication Professional BoatBuilder published the winners of the WoodenBoat “Design Challenge III,” in the November/December 2011 issue of WoodenBoat. The winning entry was a trimaran from John Marples. Included in the entries selected as notable, were three designs from four Westlawn students or alumni.

    The rules required a fast, seaworthy and simple boat, that had to have: 1) Spartan overnight accommodations for at least two people, with galley and toilet; 2) Be legally trailerable, under 40-feet LOA, and simple to launch, set up and retrieve; 3) Trailer weight under 3,500 pounds; 4) Have positive flotation, watertight storage, and mechanical or manual auxiliary propulsion; 5) Be able to sail to windward in a gale—able to claw off a lee shore.

    WoodenBoat selected as notable designs: Westlawn student Kurt Cerny’s Island Trail 22; the Westlawn student team of Jon Ames and Paulo Alva de Souza’s WWBD 26; and Westlawn alumnus Rodger Martin’s Three Nines.

    Single Versus Twin
    Thought on Installing Single or Twin Engines in Voyaging Motorcruisers

    By Chuck Neville

    Since so much of my yacht design work has focused on displacement-speed boats the “single versus twin argument” has always been one of the first questions asked and answered. Obviously fuel economy becomes a dominant concern particularly for boats that are intended to cross oceans. Historically one big engine has been more fuel-efficient than two. Big ship builders know this and usually fit the fewest engines necessary except when higher speeds are an issue. But economy of a single engine doesn’t mean just fuel consumption. It also means the savings when you buy, install and maintain one engine instead of two. That also means one driveline, one propeller, fewer thru hulls and on and on.
