The Deer Isle Koster (KDI) is a 14' double-ender that we kitted and have available for sale. The KDI was originally designed by Bruce Elfstrom, a friend and fellow boat nerd who lives and does business in Lyme, CT. He runs a very cool company doing off-road vehicle training and teambuilding all over the world (www.overlandexperts.com). A couple years ago he approached about having his KDI kitted so it would be accessible to more people new to boatbuilding. He knew he had a winner of a design and we have proven that true. The first two built, hull #1 and 2, built for his daughters, live and sail in Maine. Hull #3 is being built by another Father/daughter team in Portland, Maine, Steven and Celie Bauer.

You can read about their story on their WoodenBoat Forum thread.

Hull #5 was just launched off in Washington state outside Seattle. The boat turned out great and sea trials have gone well for her builder.

The photo below shows one of the changes made to the interior. The main bulkhead under the foredeck is open so gear can be stowed or small children! As you can see there is space under the deck for things like anchor, pumps and other equipment, leaving the cockpit free of clutter. Being a double-ender, it is critical that the boat trims on the water line for best performance. This boat is rigged with a standing lug + jib. The other option is a balance lugsail without jib. The boat will sail quite well without a jib, perhaps with slightly less windward ability. However, the balance lug will be simpler and more efficient off the wind that the lug and jib option. This is because the single big sail will provide more power than the jib, because the jib will be blanketed when sailing downwind (plus the standing lug twists more when sheeted out and the balance lug boom stays more level when sheeted out). Therefore, you will sometimes you hear of the balance lug as a "self-vanging" rig.

See my ad in the Small Boats 2012 annual issue in the advertising section under 'plans and kits'. The KDI kit is available and ready to cut. I'd love to help you get into one of these great boats.

Making of the ultimate sail-and-oar boat: The Deblois Street Dory

For the past few years, I have been working on a dory design, the Deblois Street Dory. Hull #1 was built and launched in 2010. The builder/owner sails and rows often during the season in Casco Bay, Muscongus Bay, and Penobscot Bays on the Maine Coast. Here is one of my favorite shots:

The idea was to draw a dory that was somewhat updated in the style of todays recreational sail-and-oar boat. She has a little more stability initially than a typical Swampscott. She'll be solid or plywood planked, with flotation chambers under fore and aft (below sheer) decks, and will come in kit form or be built from scratch with a plans set. There will be half-a-dozen rig choices as well as a inboard engine well. The Maine Island Trail was a consideration in designing the boat: I wanted to be able to camp cruise the trail in a purpose built boat that rowed and sailed well. This first hull was the huge success I needed to be ready to put in the huge commitment necessary for the next phase: drawing the boat in CAD. I started with the hull and getting the lines just right. This takes awhile for me because I have a very clear vision of what I want and won't settle for anything less. 

I am now finishing the computer modeling phase of the interior and strongback. The original hand drawn plans were reproduced in a CAD program called Rhino. The boat hull, interior, hydrostatics, sail rigs, and strongback are all modeled in 3D. This will be used to make the layout drawings for the plans and the 2D CAD drawings needed to cut the parts on a CNC machine. Here is a screenshot of the interior model:

I am still active designing and building boat kits. The currrent project is still the Deblois Street Dory.

Deblois Street Dory

Now that Deer Isle Koster kits are shipping and and I have moved shop back to the home based-shop, I am enjoying some new found time to carry on with the newest, refined version of the Deblois Street Dory.

The changes are mainly in the lining off of the hull and the fact that the hull is now modeled in 3D CAD allowing for precut parts to be made and a lot of tweaking to get the lines "eye sweet".

The DSD was featured in the latest Maine Island Trail newsletter and there may be a follow up article this winter after I get started on this build.

I am very pleased with how she is coming out! What do you think?
