Historical multihulls

Lucky guy!

 

I queried the boats in the photo and found out that it's actually not a wildthing trimaran in the background but a Grainger 075 trimaran "Sirocco". You can see a series of pics at this link of the nosedive:

When a Multi stuffs it like this, what is more important to get off first, traveller, mainsheet or vang ?

I'm thinking vang ?

 

All of the above......

 

Vang on a monohull. Probably traveller on a multihull as you may well not be able to release the mainsheet quickly enough

Thanks Corley, quite a sequence. Maybe those over long float bows helped in this ohshituation, boat saved itself.

 

This is a very very poor quality photo. But it was taken in 1959 and shows my first catamaran, 6ft long.

My father built it and you can see by the (long) painter he is holding that he didn't want me too sail far. My 2 year old brother is "crew"

Pray...

 

Wow, that is beautiful, you must have felt like the king of the world!!!

 

Good luck finding the vang in a hurry!

That's 'Rhiannon'. I think the hulls came from the Roland 36 (NACRA) molds that Wayne Iwamoto has in his shop in Costa Mesa, CA.

Jim Young sent me this print of Auckland's Ron Paterson patented 1975 design; the two flat bottom floats with vertical skegs were attached to the main hull by a universal joint and the system relied on tension keeping the spread out platform intact - and so, as a result, everything was very light. Jim said this was an idea worth pursuing. He sailed an earlier model, which had pedal steering and said that under sail power the rear float tended to lift and the pressured forward one went down. But this could have been changed with an angled skeg (foil) on the forward float.

 

Whoa, almost looks like kiting. Do you know if/how those floats were steered?
Couldn't they just twist the sail for some more lift? I do see some Sailrocket origins.

 

This all goes back to the late Bernard Smiths book, "The 40 KT Sailboat" published in 1963.

 

Except, OS7, Bernard Smith's boats were triangular in plan form with fixed beams whereas the Ron Paterson is very simple stick, tension lines and universal joint, sort of a forerunner to the modern kiteboard ... except that the "kite" made light contact via small floats with water.
