ARC 21
As the New Millennium arrives, the ARC-21 is ready to enter the 8.5ft. wide beachcat market. If speed is the important criteria to you, here's your boat. Three things make a beachcat of the same width faster than the competition: longer waterline length, lower weight, and a more powerful and efficient sail plan. The ARC-21 has all of these features and more. The ARC-21 with its longer waterline length, lower boat weight, greater sail area, and tall, slender, low drag hulls are the perfect combination to dominate the trailerable beach cat market.
The ARC-21 utilizes Bill Roberts "Shared Lift" concept in conjunction with low drag, high lift daggerboard and rudder designs that not only improve the ARC-21's windward capabilities but also produce a balanced helm off the wind even when flying a spinnaker. Coupling the ARC-21's "Shared Lift" daggerboard design with its high-efficiency and powerful sail plan produces a combination that will sail higher and faster to windward than any other 8.5ft. wide beachcat on the market. No other beach cat is designed like this, the daggerboard is forward of the main beam and is smaller in area than the rudder, thus the basis for "Shared Lift".
