Back to the massive looney french hydrofloiler thing..

Presumably if you fall overboard, that's it.....I guess you're looking at about a fortnight to slow the thing down, and then turn it around in waves. Suppose the only other safety issue is finding a chase boat fast enough to pick up the pieces if it ever cartwheels...!!

Of course, that would never happen in the UK, because some health and safety bod would put paid to it...!!

Vive la France - completely potty......

mines bigger than yours

im in the process of building a 1m RC trimaran but i dont think it will be ready any time soon. i have got 1 hull made though and a mould for the other two (since christmas).

600 732, will call it Sticks and Stones when i get round to it.

When you take a historical view its amazing what has been considered to be ugly in the past... The J Class, for instance, were considered ugly when they came out, hard as it is to believe now... Things that work well have a habit of coming to be regarded as good looking...

I have designed a foiler for Weymouth Speed week for my University, and through the processes of design which we carried out, can make comment on the Aero-skiff as it is too heavy and underpowered to perform as claimed. The design which I worked on performed very well when we put the numbers into the performance prediction programmes and was sea worthy in canoe body form when we simulated it in Maxsurf VPP. The reason that I commented on the Aero Skiff is that if you do the maths, it simply doesn't add up to what it's claiming.

Although Andy Paterson will tell you that's what he did when he designed the first Axeman Moth... That it was a clean sheet of paper without reference to what was currently successful. There's always an exception.

I cant think of many/any "mould breaking" boats off the top of my head
(Jim?!), but the one thing you cannot do is ignore what works. This is what
Doug appears to have missed and tried to make a boat with different
everything on board.
He has then tried to publicise the fact that it works, with no visible evidence
and that it is going to revolutionise sailing for everyone. (I can see why
everyone has either fallen over laughing or put their backs up)

All the designers I know wont try and make that sort of claim, they just get
on quietly improving things... Like the 45 knot trimaran that has been
around for nearly 20 years and has been rebuilt 5 times!

Well said Rupert.  I concur.  Good points well made.
