Broker's Comments

There is absolutely nothing ordinary about ARCHARNE!   A rugged and dependable motor yacht for short handed explorers, she has a comfortable interior and simplicity is her watchword.  She runs on fumes and really goes to prove that special yachts can have a successful second life if the makeover is properly managed.  She is also very accessible in price terms and we are excited about the possibilities that she offers.  

Owner's Comments

After building four successful world cruising expedition yachts, Ocean Voyager is pleased to offer its latest expedition vessel:


ULDT (Ultra-light displacement trawler) “Acharne”.



The vessel was inspired by Ocean voyager trademark: reliability, safety, simplicity and design innovation.


The conversion hull was carefully chosen for its superb workmanship and its weight displacement. The hull was built flawlessly by New England Boat Works to a Bill Langen design. Constructed in all carbon and epoxy and nomex core, vacuumed and baked to exacting specifications.  The original hull was chosen for its performance upwind, strength, long waterline and seaworthiness.


“Sagamore” was the first "new generation" IMS  racing boat to be built by New England boat work utilizing phenolic honeycomb core (1-1/4" thick) After ramping up the "oven temperature" for five hours, the 80-foot hull was carefully "cooked" in NEB's post-curing enclosure for 12 hours at 80 degrees Centigrade (the IMS legal limit). With precise monitoring of the temperature, using an array of sensors implanted in the laminate, insured that a complete mechanical and chemical bond between the carbon and Nomex was achieved.  (NEB website)


In late 2000 under new ownership “ex Sagamore” was racing in the Pineapple cup and suffered rig failure. The owner lost interest in racing and we purchased the boat shortly thereafter.  After building and cruising many large trawlers, we were convinced that she would make a perfect hull for a light, long range power cruising boat. The structure was built for loads that far exceed the requirements for a power boat, so we knew the strength was there, and the hull form would make for a very fast cruising speed with incredible economy. The team at Ocean voyager redesigned the layout, draft and power configuration as well as stability performance under the most challenging condition.

 Under sea trial and long distance cruising the boat proved itself to be our best and fastest cruising trawler.


The requirements for “Acharne“ performance were the following


1.  A vessel with a fine entry for upwind condition and long waterline for speed.  To do this the vessel must be light, with an upwind design configuration and Acharne, at 20 ton fully loaded compares to the weight of some 40' sailboats.


2. A vessel able to be operated ONLY by two people without any crew;   requiring low, low maintenance on very simple mechanical systems which are easily accessible and a simple, and our trademark interior, simple and functional.


3. The vessel must have the lowest carbon foot print and fuel-consumption possible for an ocean going powerboat capable of long passages.  A new Milestone for Ocean voyager.


4. An immense back deck, a trademark in all our conversions, with comfortable outside accommodation, water access for diving . easy dinghy retrieval and storage on deck, deck stowage to a good size tender and one motorcycle and easy access to the dive compressor and dive gear. When all the toys are unloaded 15 to 20 people can have a comfortable party on the back deck.


5. Green. We always install very large solar panel arrays, Ocean voyager has achieved a zero diesel charging electrical system at anchor with limited daylight air conditioning operated by solar. Another milestone.


6. Stability.  A vessel which can sustain heavy weather with minimum challenge. This was achieved with low displacement, inherent stability from low deck and cabin weight plus inside and outside ballast. We did not want to build high superstructures which would need additional stabilization. Keeping the boat light and low profile was our priority. We installed hydraulic fin stabilizers for comfort, not for safety.


7. Speed. We wanted to go against the weather comfortably at 9 to 10 knots and go downwind at 12 knots or more. Ocean voyager has achieved this. “Acharne” surfs beautifully downwind with little of no yawing or pitching common to shorter waterline trawlers without the help of stabilizers in operational mode. We turn off the stabilizers downwind and gain ½ knot. The boat is perfectly balanced.  We have averaged 10kts at 1500RPM, or 2.7 gal/hr up wind and 11.5 /12kts downwind with 2.2 gallon per hour. The light displacement with incredible strength has achieved this performance.

 Example: Fort Myers Florida to Luperon, Dominican Republic/950 miles/ 94 hours, averaging 10.2kts AGAINST the notorious Caribbean trade winds and 15 to 25 knots along the whole northern coast of Cuba and Dominican Republic.


6. The design is a personal boat, arranged for an experienced couple and occasional guests. She has 2 queen bed staterooms with 2 heads and one small possible child or crew berth forward accessed by a hatch with a folding berth. The interior is elegant, modern, lightweight and functional.


Acharne is another successful 21st century Ocean Voyager achievement. In converting the vessel we have perfected our search for the “perfect” cruising boat. She is easily handled at sea and at the dock by 2 people. She has a minimal carbon foot print, she is great to live aboard, light, airy and lots of ventilation, easy to maintain


The boat is currently moored in Antigua and is easily available on appointment
