You would have to agree with me that these are strange times in the U.S. and with an election coming soon, hate is literally promoted as a patriotic reaction to a rapidly changing world and good ole religious ferment is having expressions of violence on an almost daily occurrence. This makes me a nervous guy, and I am not alone in this feeling and reaction. But any keen observer of politics, and world news would know that this is really nothing new, it simply gets more play on the outlets for information media, social, print and screen. No one knows what to believe any more in a world where lying is an everyday occurrence and any fool can promote whatever agenda they wish and in a keystroke it is disseminated around the earth almost instantly.

But enough of this nonsense, let’s think of a proper design to sail to the ends of the earth while we still can freely and safely and this design would be one of my proposals for the proper platform to do that with. I note that the Bluefin 50 Passagemaker first started with a sheet of paper on my drafting table in early 2012 (if I am to believe my notes), visited about every six months till current times and I just today blew the dust off her to show to you.


Hallmarks are a box keel with almost full headroom in the engine room, a heavy and tall John Deere diesel engine in the box, with shaft in a straight alleyway to the stern. Ballast in the bottom of the box keel in two forms the first layer on the proper bottom of the keel box being made of a full 1 ½” keel shoe of type 316 stainless steel. This affords grounding possibilities and upright stance on any shelving beach. Just above that in the bilge is another 8000 lbs. of lead shot in an epoxy matrix in the bottom of the box. The epoxy means we have a smooth and easy to clean bilge but with the keel shoe and the epoxy/lead shot you have a lot of stability in the base of the boat.

You can see easily the layout, a three cabin version, galley up, proper sleeping cabin forward sporting full head and shower and aft a sitting room with its own head, quarter berth and dinette table either functioning as a shaded and private living room in the evening or if your inclined to take crew they would have a private space away from the skipper and first mate.


A simple sailing rig, two jibs on roller furling, and a boom furled mainsail all this set on a tabernacle mast (just in case I take a notion to want to do some canal cruising), the sail panels small enough to be easily handled but adding to make literally twice the effective cruising range to the vessel.

Twin booms on the sheer that hinge out to 45 degree angles each side fly paravanes on a chain/nylon line pendants, this is the most effective and simple way to add extra stability to a vessel when the weather and sea conditions dictate the necessity.

She is purposeful, uses all the tricks in the book for an easy to use Passagemaker boat that is stable and has good capacity for cruising all waters, mid to high latitudes and for getting onto cruising while we still have the capability of doing so! Enjoy.. Sam
