After decades of cruising and racing the first owner worked out a requirement paper of 40 pages describing how his ideal cruising yacht should be. The TRINTELLA Yacht came by far closest. Enormous effort has been undertaken to even improve the characteristics of the boat.

With the carbon rigging and the customized keel the yacht became very stiff, sailing very upright comparing to other boats, which makes it even safer and faster. The yacht proved to tack at least 5° higher than any other cruiser in the 50+ foot range. For passage planning the assumption is an average speed of 6.5 kn which is regularly exceeded. With full sail area it can –in good conditions- sail in 8 kn of wind.

The yacht is very sturdy. It takes the waves nicely and is a dry boat in nearly all conditions.

The doghouse is one of the best features. It gives protection in harsh conditions and it gives shade and ventilation when it’s hot. The centre cockpit serves as the prime living and dining area underway and in harbor.

All equipment (Mastervolt, B&G, Lewmar, Spectra watermakers etc.) have been chosen to have the best and most reliable products. Cost has not been a criteria, flush Rondal hatches have been chosen to produce a beautiful and safe deck. The big wheel allows precise and easy steering. The hydraulic components and the bow thruster make the yacht easy to handle.

The sail plan allows an unimpeded view to leeward. Reefing is easy and any configuration maintains a excellent sail shape.

The Canadian maple and matching colors of upholstery and curtains give the yacht a rarely found generous and beautiful interior.

For the music lover Pioneer top end and Bose were the best choices.

The yacht has a stock of spare parts that is incomparable. Only a yacht that has been used for long distance sailing can have such a comprehensive and optimized list of parts.

The yacht has been used strictly private by a retired couple and a professional skipper. The yacht has been maintained and improved professionally regardless of cost. Extensive refit work has been undertaken 2005 in New Zealand and more work has been done end of 2006 in Trinidad.

The second owner continued to refit the yacht and update the equipment. The rigging was replaced in 2010 in the UK, domestic batteries changed, electronics upgraded and watermaker changed to a more efficient one. The engine got its major revision at 3000 hours and sails have been changed, continuing using the respectable sailmaker Doyle. Liferaft, an additional EPIRB and the solar panel were added later. Leather upholstery and the headlining was completely changed as well.

The yacht is in the best possible condition. It has sailed both owners across oceans safely and in comfort. It is ready to go for any ocean passage.

SEVEN SEAS ADVENTURE is a superb semi-custom yacht that has been conceived and built with the idea in mind of serious sailing at pace. The level of craftsmanship throughout is astonishing. Totally capable, and supremely comfortable, she has met her brief admirably.

A good sized and yet generously proportioned yacht, which is easy to handle and which has huge range and endurance capabilities. It is virtually unique to see a yacht of this size built to this standard.
