where is the hellipad?

Oh c'mon guys - this is a shining example of how the superyacht crowd are going green....

if you made it big enough, you could harvest algae and process it into alcohol for fuel

Here a clever small waterballasted sailing boat, performing several features I really like. Among them what they call Asymmetric Capsize Buoyancy (ACB) and a boarding permanent step in the trailing edge of the rudder.

http://www.swallowboats.co.uk/content/view/115/110/

From the site:

"Once fully inverted another big safety feature automatically kicks in. Her Asymmetric Capsize Buoyancy (ACB) is a real life saver. Boats that will self right from 90 degrees are usually also very stable upside down. Two or more crew have enough weight to right her from a full inversion, but ACB makes this possible even for one relatively small crew member. It works by flooding one side buoyancy tank when inverted, which destablizes the boat and in about 60 seconds, gives her a noticeable upside down heel angle. The skipper should wait on top of the up turned hull and right the boat by leaning on the centreboard, helping the boat heel to the same side as that induced by the ACB. Once righted, the water in the buoyancy tank floods out though the outboard well via the self draining cockpit floor.

........

We have talked a lot about capsizing, and righting, but getting back in can be a real problem for all but the young and fit. BayRaider has plenty of positive buoyancy so floats quite high even when swamped. Our solution has been to fit the rudder blade with a permanent step in the trailing edge, rather like a winglet at the end of an airplane wing, it sits about 12 inches below the surface and acts as a step for re boarding. The mizzen mast is within easy reach to grab hold of as is the stocky mizzen mast partners."

Pericles brought my attention to this contest:

PBB's DESIGN CHALLENGE II

Design Parameters:
Must be trailerable for affordable launching, over the road transportation, and storage.
Max beam 8 ; max length 40 (legal trailerable dimensions in many states)
Minimum length 24 , stem to transom
Trailerable weight (with engine) should not exceed 3,500 pounds
Must burn less than 2 gallons per hour (7.6 l/hr), maintaining a 10 knot cruising speed in a 2′ (0.6m) chop and 15-knot breeze while carrying 800 lbs/362 kg (family of four). Favorable consideration will be given for continued efficient fuel consumption and good seakeeping abilities at speeds in excess of 10 knots
Must include at least Spartan overnight accommodations (berths, head, galley) for two adults and two children
Must be a new design
Submissions should be the designer’s original, previously unpublished work, and include lines, profiles, sections, table of offsets, accurate weight study, cost calculations, and performance predictions. (All designs will remain the property of their designers.)

Thanks, Perry.

Cheers.

Now that's starting to look interesting! Designing a 40' x 8' boat that can sleep 4 and weighs less than 3500lbs should result in some interesting boats....
