I'd be willing to type about it. Give all kinds of opinions about it. Then not do it.

As far as sponsors go, that would be up to the teams. These guys aren't trying to make a business model or spectacle out of it.

But that is severely limiting the participant pool. You are already limiting it to people who would be willing and to do it. By forcing the sailors to come up with the money themselves, you are also limited it by those who can either afford it, or drum up their own sponsorship. These are radically different skill sets IMHO. The kind of people that are willing and able to sail a beach-cat 1000 miles (possibly non-stop,) are not the same kind of people who are well moneyed, nor are they the kind of salesmen that they can get companies to cough up the necessary cash. Sure there are examples of people who can pull things together well enough for a one-off type event (crossing the Atlantic or whatever,) but an annual race is a whole different ballgame.

Either way, asking sailors if they are interested is pointless, you don't need a whole lot of sailors to participate. What you need to make this sort of thing successful are organizations.

I think Mike wants to pull a Randy.

Are any of the beachcats able to do it non-stop? Carry enough provisions and three guys to sail 1,000 miles?

And N-20, Tornado, F-16,etc...one design. I would assume.
I'm just a sounding board for this and really know no more than I've posted. They may want to do a box rule, (he said one design) , don't know , but to me that would just create a hellacious arms race and reduce overall participation, just MY opinion.
It sounds as if they may be shooting for absolute minimum hassle from an organizing stand point ergo the Teams are responsible for everything deal, safety, lodging, bail,etc..
And PTP thanks for the vote of confidence ,if the interest and participation aren't there, then you are right it probably won't happen.If there is interest ,hopefully it will.

Doing that on a beach cat would be impossible...

Hang on a second. How many 4ksb's make this trip routinely? The trip itself is doable, how fast is the question.

I'm thinking a young, skilled crew (3 lean, smallish guys) on a 20 something could make the trip without stopping on the beach to switch anything.

You're talking about anything from 96 to 170 hours of time on the water. Planning to sleep on a beach cat over that time span would be impractical. Only in light to moderate conditions could you possibly catch any z's while underway - and you can't plan for those conditions to happen. I wouldn't think a non-stop trip is practical on a OD racing beach cat under 20' where on-board sleep will be required.

If someone does sort it out, carrying the third person and provisions for the entire trip would be more of a time/speed penalty that pulling into the beach every 12 hours.
