I can't remember what I used to make it, but I whipped this out in like 15 minutes one time....

The hullshape reflects my lack of basic design principle.

Not really - buy an F18 - approx halfway between the two lengths, more stable, more room - and more competition than the F-16. Plus a better work-out moving it around the beach. What's not to love?

Actually the F16 has more boats on the line than F18s in these neck of the woods.

Getting back to the original thread. try www.avast.com and download their home software, its free, automatically updates and has sped all our machines up significantly.

Freeship is a powerful boat design tool and will do far more than just draw and render. Give it a go. Look up the boat design forum, both the multihull and the software threads and you will gleam alot of information that is pretty factual and not tainted by our loyalty to one or another F boat. wink

Okay! I can't help myself so here goes. I'm not trying to say anything, I'm just sayin'. . .

Are we too high tech? There was a lot of gear failure in the last Tybee and by all accounts conditions were pretty mild. Would the first generation H16s have had any problem with those conditions?

FWIW a 4ksb wouldn't be very impressed with a 500 mile run.

What a lilly livered piece of crap disclaimer. I thought this thread was about a boat design program.
Pete when was the last time you raced in a distance race on an N-20 ,F-18 or a Hobie 16? So where is this pool of knowledge coming from?

I'm gonna check out that Freeship site. Hopefully my computer challenged self can use it.

If you really want to have a good time, try installing Norman AV Corporate edition in a network.

Stick it!! You have no sense of humor so kiss off! Before you design something, it might not be bad to have an idea what you want it to do!

Rhinoceros and Maxsurf for all your boat design needs. Both based on similar mathematical/modelling methods and both fairly intuitive with good help.

Rhino, from McNeel & Assoc, can be downloaded free for 25 saves or prints. Maxsurf, from Formation Design Systems, has a no save demo. Both are unlimited use otherwise.

Rather than printing from Rhino, you can save some of your 25 "saves" by taking a screen shot.

"I'm not trying to say anything, I'm just sayin'. . ."

Well, what exactly does it mean. Sounds like you wanna say something but your scared to stand behind your words.So you want to design a Hobie 16, is that it?
There weren't anymore "failures" in the Tybee this year than any other. There was a sail failure that had nothing to do with the race or the boat.
And your right ,I have NO sense of humor, just ask anybody.

It's nonsense from the "Sopranos".

But, screw it! You wanna hear it, here it is. 500 miles is not much of a distance for a sailboat. Dozens, probably hundreds, of monohulls make journeys of many times that distance annually. There is a veritable migration of boats down the eastern seaboard each spring.

I'm not sure what the distance standard over time is but 180 miles in 24 hours rings a bell.

So one interpretation of the Tybee would be that the difficulty is an indicator of the unsuitability of the boats being used.

I'm not saying it isn't difficult or that it doesn't take a lot of skill. I am saying you're using the wrong boat. Hence the design questions.

That's what I wanted.
I don't watch alot of TV anymore. I thought it was regurgitated SA spew. I see it over there alot.My bad.

My take on the right boat for distance racing,the longer it takes the more stuff you break.You can even see this from inside the same fleet.This refers solely to racing.
Cruising a boat to the South with the snowbirds is a whole different cup of tea.With an average speed of 7.5 (the 180 in 24) I'd call that cruising or miserably slow racing. Plus it'd be awfully hard to beach land and launch a monohull. That's where stuff breaks and that's what makes the race more challenging. The point of races like the Worrell, Great Texas, and the Tybee is the fact that the boats are not decked out comfy race boats. Whether or not that makes it "suited" for the race is up to personal interpretation. Since the races were designed around using that type of boat I'd say it is .
What boat do you think would be better? A 16 is going to take considerably longer, which is harder on the boat and crew. If your designing something specifically for that, I'd combine a Nacra-20, a tiger and a Tornado.

Regarding the Tybee specifically, I think developement would benefit by an "Open Class" with few if any rules regarding design. Because you are launching through surf, the transom hung rudder needs to go away, or fit a couple of robust sweeps so the crew could power out throught the surf (think of the Australian life guard competition where they row a dory through very heavy surf).

something is wrong with my reply screen. can only write short messages.

I have to wonder what a Tornado would have done in this years Tybee with an old style, dead down wind spinnaker? In the cycle of innovation, imagine a modernized square sail, using a carbon spar and HUGE light weight sail.

One thing to be aware of is , what you start with you sail with. There is no time to switch things around. As tight as the racing is, every second you lose you will NOT get back.

How about switching a light weight, symmetrical spin for the more robust asymmetrical spin? Not allowed under class rules but allowable in an open developement class.

I know a guy with a 40' cat who launches his spin from a bag! Piece of cake if it's packed right, impossible if packed wrong. A light weight spin for a 20' cat probably would weigh only a lb.
