“You will need to have some vision”

This 65 foot all steel constructed , tri keel vessel was custom built by  Mid Valley Marine, using a design by the well known naval architect, Nils Lucander.

Its purpose and intent was to be a self sufficient yacht capable of long distances. Having great stability and  a relatively shallow draft for a yacht of this size and weight. Additionally, to be able to approach shallow waters for the purpose of exploring lands beyond the horizon.

Although its not a “stylish yacht”, it was purpose built by the builder / owner for his own explorations later in life. Unfortunately, his life ended before he could fulfill all his dreams and the yacht has been put up for sale by his estate. Replacement value was indicated at about 3.5 million USD.

Vessel Information

There was sprayed in foam insulation throughout the inside of the hull and superstructure. The vessel was built to greatly reduce thermal transfer since it does not have air conditioning ( could very easily be added but has not been needed) and was not intended to live in a marina. It has large forward facing hatches that allow for very generous airflow throughout entire vessel while at anchor.

There is extensive record keeping of maintenance aboard the vessel in the logs. Driveline is a Commercial grade. Hours on motors and trans are extremely low for the equipment all cooler have been recently cleaned at the last haul when bottom was done. Everything is in good working order.

Presently, once a week the pumps, generator, and  engines are checked and all systems clean and freshen up. Hatches are open for a few hrs. The vessel should have a range on full fuel of approximately 3500 nautical miles. This is intended for modest speed of 6 1/2 knots and it is well-suited to long range remote cruising and live aboard. It  could also do very well as a small dive operation with tank refilling equipment and nice aft deck to work off.

The case for Three-Keelers (tm), By The Naval Architect

Twenty years ago, I conceived the Three-Keeler(tm) concept, now available on both power and sailboats, widely used on commercial craft, and offering all kinds of advantages.


On Three-Keelers(tm) the center keel is eliminated aft and substituted by twin husky aft keels-one on each side about halfway out to the waterline and extending from near amidships aft. The keels are so large that the engines fit partly into them, producing short level-with-waterline shafts for maximum thrust with minimum alignment and vibration problems.


The Three-Keeler(tm) concept reduces roll so much that artificial means to control roll are seldom needed. Course holding is enhanced, lateral drift largely eliminated, and only minor rudder correction is required even when running on just one engine. Broaching is virtually impossible since two aft keels offer double the resistance against steep quartering following seas.


On small boats, twin engine installations generally cost more than one larger unit, but this is not always true. On larger boats over 50 or 60 feet, two smaller engines cost less and, regardless of size, smaller engines together cost less to maintain. Having a single keel on center forward and twin keels aft allow the boat to be beached at high tide, and to stay upright without damage. Any repairs or services required, such as clearing a fish net from a fouled propeller can be made; and when the tide returns, the boat is re-floated and on its way. With no cradles or supports needed, big savings can be gained during haul outs at marinas.


Interestingly, when wave making is reduced, as is the case with my Three-Keelers(tm), added weights become less detrimental than has been generally believed, and this also allows the use of smaller than normal engines. I do advocate deep reduction gears to permit use of larger diameter and more effective propellers to overcome strong currents, to push against strong winds and big seas, and specially to be able to escape off a lee shore in a storm.


In case a boat such as described here hits a rock or submerged container, the metal may get a dent and if the boat bumps into a coral reef, log, or other debris, nothing will happen to the boat, but perhaps a whale may get an everlasting headache!

Finally, the new Three-Keelers(tm) both power and sail, are performing better and neither type will rock or roll at anchor. They are, in my opinion, the ideal long distance cruising boats for the 1990's and beyond. "
