An interesting concept, the illustration doesn't give any thing away but the idea is that the hull shape generates useful aerodynamic lift when the engines generate a certain speed.

This issue has an interesting article about foiling model multihulls; lots of excellent pictures, no real information about the designs.
They look as though it could be a way of experimenting with foils minimising the logistics of cost, transport and crew.

I believe that over a reasonable distance(?) it is accurate but the best GPS units are I think differential and accurate in position to cms where as older (and ? cheap chips ) accurate to 15 metres so the speed may be in error but it may be worthwhile as then on has automatic speed recording at know...

Does the winch work both ways ie. allow a controlled drop of the keel rather than having to ease the tail of the rope from the tackle?

Not a new idea Tony ?Blofeld and his "Speedwing" at Speed week many years ago had a wing shaped bridge deck to help generate vertical lift as well as inclined lifting foils, however it is being developed commercially for a high speed ferry; www.aavessels.com their web site is worth visiting, plenty ...

Sorry but when I tried the link it didn't work, instead try their home page www.maritimejournal.com and click on news and select power and propulsion in the menu, the resulting page needs to be scrolled down 4 or 5 times to find the entry.

I visited it today and the show seems to have been brightened up somewhat. When I arrived at about 11.30am it was fairly quiet but by lunch time it was much busier.

I went yesterday and as usual there was lots to see, I got the impression that motor boats predominated in particular RIBs and small sports boats. there were plenty of small boats to look at and few sailing cruisers up to about 6m then there seemed to be a gap until 10m length too many to look at in...

Hello The photos seem to suggest you have built the boat itself but the rig appears to be a model, I find your project very interesting but feel that the boat ought to be sailed with a conventional rig to establish its performance before moving on to the new rig.

Just in case any member wants to enter the rules have been changed and there will be two events.

Fredthecharlie

Thank you for your interpretation, I agree that the boat mass will be increased but hopefully its weight carrying ability shouldn't be affected; I think that having considered your thoughts a high density bulb and an enlarged volume of the immersed hull might be better it should certainly produce a ...

Fredthecharlie

My thought was that it would not increase the displacement but would provide a righting moment when the ballast bulb came out of the water, ie at about 80 degrees heel, it would increase imersed surface area however.

Thank you for the explanation, if I understand it properly it means that th rudder mout swings to the leward side of the boat and offers the benefit of twin rudders using only one.
