Passagemaking Motor Vessels:

This family is not one hull type carried through different lengths, but 8 or 9 different hull types having the commonality that they are all designed for long ocean passages, obtaining  2200 or more nautical miles at their service speed without refueling. 

The 54 single chine V bottom troller shown is the largest of this group, and the smallest is 12 meters or 39. 

Another member of this family is a multi-chine or round bottom fantailed type of fishing vessel, the smallest of which is 11.9 meters (39). She has a range of approximately 2400 nautical miles and a service speed of 6.6 knots with a fuel capacity of 450 gallons. Her beam is 3.9 meters (129). The upper limit for this type of hull would be around 70.

The ocean-going dory is another member of this family. They range in size from 33 to 52 over the rails. The larger one is the most popular. She has a beam of 14, a service speed of 7.4 knots for almost 2800 miles on 468 gallons of fuel, and she is flat bottom.  This is the least expensive hull to construct for her size. The construction time is a fraction of the time necessary to construct any of the other hulls in this family of ocean cruising motor vessels.

Another member of the family is my ship hull. This a single chine V bottom hull with a raked stem, and the size range is from 45 to 90. For example, on the 15.7 meter (516) hull, she has a 3.52 meter (116) beam, a service speed of 7.75 knots, and on 500 gallons of fuel has a range of 3100 miles. The smaller hulls have 4.5 beams to the length, and on the largest of the hulls this drops down to 5.0 beams to the length. The three vessels above where the service speed is given have one other common feature, and that is their displacement is 11 tons. 

Double-ended trawlers are also members of this family, ranging from 26 to 70 in length. They are round bottom or multi-chine steel hulls. The 26-footer accommodates two in the minimum of comfort, but with all the necessities of life.  It is not until 11 meters or about 36 is reached where reasonable comfort is available for long voyages. At this length, one has a sleeping cabin with water closet separated from the saloon and galley by the engine room. The saloon is large enough to permit berthing for short-term guests. This size vessel is large enough for a couple to consider as a permanent home afloat. From 42 and up, it is possible to accommodate four persons in comfort. 

There seems to be a trend today of having more and more persons aboard for ocean passages. In my own instance, Jean and I do the passages and think nothing about it. These ocean voyaging vessels are all fitted out with an autopilot, which is the same as having four more in the crew without having to feed them or put up with their tantrums. Should the autopilot fail, both of us have done enough wheel watches that it would not bother us. It is not the end of the world as some would have us believe.

More information on all of the vessels in this family, with profiles and some photographs, can be found in COASTWISE AND OFFSHORE CRUISING WRINKLES. A chapter is devoted entirely to ocean voyaging motor vessels.

If I had to pick a particular vessel in this family as ideal, it would be impossible, for all of them have the same capabilities; they are all seakindly; most are based on successful commercial fishing vessels of my design; and all have positive righting at 90 or more.
