Accommodations
Hammerhead incorporates a very comfortable tri-cabin layout that provides a large galley and saloon with a fantastic view, a double cabin forward with it's own spacious head and shower. The private aft cabin with ensuite head and shower and ample storage space provides the space and privacy normally associated only with large catamarans.
For additional crew, the main salon has 2 seats that easily convert to single berths, or 1 single and one double; as many as 7 can be accommodated overnight.
Performance
Hammerhead's sailing performance is extraordinary. She can lope along at an easy 20 knots with mainsail and jib alone. The vessel has seen extended periods of STEADY 19 to 20 knots of boat speed with a single reefed main and full jib, beam reaching in approximately 20 knots of wind. Steering in these conditions was a one handed affair. At high speed the helm is easy and balanced with absolutely no feeling of loosing control. Hammerhead is capable of sailing at 24 to 25 knots without surfing and without a spinnaker.
Hammerhead's windward ability is excellent. With her centerboard down draft of 9' she has the ability to drive to windward like a freight train. In moderate conditions she will tack inside of 80 degrees making 8 to 10 knots through the water. As wind speed increases the fastest way to windward is to open up the tacking angle slightly to build more speed- which offsets the greater distance. Boat speeds of 11 to 12 knots hard on the wind can be achieved with proper sail trim.
In ocean conditions her motion through the water is very comfortable. The narrow forebody can slice through waves at high speed without pounding. Downwind she is steady as a rock with minimal roll and yaw.
Single and short handing is easy with this trimaran. All sail controls are led to the secure midship cockpit.
Shoal Draft
Twenty nine inches, less than 2 1/2 feet of water is all it takes to float Hammerhead! With a pivoting centerboard and a retracting rudder the shallow draft of the hull can be fully exploited. Vast areas of the Bahamas become "cruisable", secure hurricane holes are easier to find, over-crowded anchorages can be left behind for secluded coves inaccessible to most boats.
The pivoting centerboard is contained in a trunk located beneath the cabin sole and does not impede interior space. The board itself is positively buoyant so that it floats upward into the trunk if the pull down control is released. Up and down controls are led to a simple self tailing sheet winch in the cockpit. Except for the way Hammerhead tracks to windward you'll never know the board is there. In order to make sallow draft practical the rudder must also retract. Her rudder will retract automatically upon impact with the bottom or any submerged object thereby preventing rudder damage. In addition the rudder can be steered while retracted. This allows the rudder to be retracted to the draft of the hull and still be functional. Hammerhead can be sailed or motored in 2.5' of depth!
Mast Height
Masthead height under 65' so that Hammerhead will clear the numerous fixed bridges on the eastern U.S. and gulf coasts allowing unimpeded travel through most of the Intracoastal Waterway and other important harbors.
Owner's comment:
A proven performer - at first sight Avalanche appeals to sailors as a very sexy, very fast sailboat, with a very modern design. However, the sailor will be astonished to realize that she is also exceptionally seaworthy when cruising out in heavy weather! After many years of sailing her around the world, in some pretty intense weather, I have never doubted her solid sailing platform and her ability to withstand the harshest of conditions. Even while hitting speeds of thirty knots in the Southern Ocean, my crew and I never felt in harm's way. We always had confidence in the boat! Avalanche is a very safe world cruiser! Including a longest recorded daily run of 528 miles in a 24 hour period - Southern Ocean, New Zealand to French Polynesia Passage, August 15, 2017
Having completed a circumnavigation, the vessel is currently in California, where she is for sale - ready for her new owner, to take her on her next adventures.
