BigZ Do a search on the Procyon Project, or something similar to that spelling. The boat had some different techniques, including the inverted-V masts. Might have been built by Hunter, can't recall for sure.
Can't remember the end results or if having the main in the clear air was a big help.

Freedom 40s have free standing masts. I think that when engineered properly, they are a great solution. While they are definitely seaworthy and do the job, they are not high performance, just low maintenance and low worry.

You might check out the flying lateen.

ArgleBargle as i said if you read the original post, that is not the design i suggested and i was asking if anyone had heard of a tripod design.

Rainbow Warrior III is no beauty, but it is a working boat and when compared to Rainbow Warrior I is a work of art.

thanks in any case for your lovely response.

Hesper And you think THAT'S more elegant that a mast with stays and shrouds?? Oh, well - no accounting for taste. And by the way, the Camel could dogfight a lot better than an F-18.

ArgleBargle thanks for the link!

Trying to locate a Delta Rig Sailboat - SailNet Community

Sorry, Argle,, there's nothing truly 'new' in the world anymore.. patent offices may as well shut down!

ArgleBargle are you sure three smallish carbon fiber tripod legs will weigh more than a carbon or aluminum mast plus stainless steel stays plus stainless steel shrouds plus spreaders added together, or is that a guess?

I bet it comes out pretty close.

LookingForCruiser Uhhh, it's got a helipad under the boom. Who thought that was a good idea?

That is one ugly looking boat...

How about a boat with no mast?

I've always thought a single mast in compression stays and shrouds under tension a rather inelegant design - someone has said "Sopwith camels used stays, F18s don't".

The unstayed Nonsuch's and Freedoms looked OK, but having a single enormous spar also seems inelegant.

A tripod arrangement with an inverted V-shaped "mast" and a rigid back"stay" or forestay seems to me like the most elegant solution. You could still potentially incorporate a boom rotating on a short midline articulated spar where the mast would normally be.

I thought I had invented that in my brain, but like most such thoughts I eventualy found a similar design in the new Greenpeace Rainbow Warrior III, see:
Greenpeace orders new Rainbow Warrior
Although it doesnt use a rigid forestay.

Anyone know of a smaller sloop rigged vessel that has used a similar design?
