  • Our desingers reply: "Almost every aspect of design is a compromise. In multihulls the balance of safety vs speed drives many design parameters. Parasitic drag makes a large percentage of the total drag of the boat and the topsides - the bow especially. Remember catamarans operate in high apparent windspeeds and at close apparent wind angles. You can make a safer (and slower boat) but some teams didn’t capsize so the design appears to be well placed - close to the edge but no over it."

  • there is nothing safe about these boats . come on guy dont kill yourselfs and look at this boat

    this is a safe boat it wont flip quadramaran the safer boat

  • @barryperrins "reverse bow" allows more buoyancy at the bow and helps to PREVENT pitchpole and/or capsize. When you see the bow digging into the water (often rounding the top mark) is a result of the increased load on the front of the boat from the gennaker, which is fore of the center of effort, and thus tries to flip the boat forward (boat tries to rotate around the center of effort...like a hinge). The increased buoyancy from the reverse bows helps to prevent this phenomenon.

  • We had those guys here in Plymouth. I Cant understand why the boats have an upside down bow design. When the front of the boat goes underwater the backward rake of the bow makes it dig in even more and so tries to flip the boat. I saw it happen so many times in Plymouth.

  • the boats are great, but the editing is awful. I want to see them sailing for more than 1 second.

  • @Ezlock you mean sailing :)
