OK, so let's speculate, seeing as the E20 has not been built as of yet. Here's the link to the article describing the boat in detail, complete with some links to vertical strip foam building techniques to show that the process is not that difficult for a guy who has already built a boat, or two. http://www.lunadadesign.com/europa-2...-trimaran.html
Built in carbon cloth, the E20 could be ready to sail in the low 400 pound region for all-up weight. It would be less expensive in glass laminates with a weight offset as the major adjustment to the final product. I expect the boat to be powerful upwind and especially quick when making use of offwind angles. Because of its enhanced righting moment due to beam width over a trailered beach cat, it should carry sail further into the upper wind regions than a cat, giving it significant advantages. The boat has a comfortable cockpit area that could be useful for crew rest. To that end, I would suggest a collapsible dodger just aft of the mast with tapering side curtains to keep the resting crew dry and warm. I'd further equip the boat with ultra light weight seats on the aft end of each side trampoline surface that have fold-down backs to keep the wind drag to a minimum. These seats would give the skipper more comfort and allow for a bent leg stance while driving for longer periods.
The amas are modeled after those seen on the Maxi-tri, Sodeb'O. They have wave piercing bows only at the forward ends. This allows the boat to be driven more aggressively with reduced hobby-horse pitching moments. The volume of the bows has been flipped top for bottom to maintain the forward reserve buoyancy needed to resist pitch-poling moments. Immediately aft of the wave piercing feature, the amas open up to provide full, offshore style reserve buoyancy at 200% of displacement. Experienced sailors will be able to push the boat quite hard without fear of tossing it over.
I would not suggest that owners of this type of boat put it to the crucible of trying to push hard in any race before they know the machine. Instead, I would suggest that the crew embark on a regimen of regular sailing sessions in a wide variety of weather and sea states so that the sweet spot can be fully understood before pressing the boat in a competitive environment. For example... What does it take to fly the main hull so that it is just kissing the surface and how easily can it be held in that state without the danger of capsize. At that point, I think that a skilled crew that has gotten to know the boat and its quirks, will be able to put this ride up at the front of the EC, doing battle with Sew Sew and Lumpy.
Paddling this machine would be about as easy as it is to paddle the Tornado, which isn't very easy compared to other boats where the paddling function has been included as a major component of the design strategy. If the wind is cooking, then this boat should be a serious threat, If the wind dies, then it's going to be one ugly slog to Key Largo. Dead air could provide for the interesting scenario of all the sail rigged Krugers, Hobie AI's and the XCR's going right past the likes of the Tornado, Randy Smyth's tri and the Europa 20. There might be a bit of salvation if the side tramps could be rolled out of the way, the rig struck and the crew gets to hammering with paddles on each side of the main hull. Other than that, it's all about the wind for boats of this type.
