Whoa! "Prototype" is always spelled with a $, isn't it?
I will have to belly-up to the keyboard and get started.
Hi all:
I was the Test Pilot for the Tri Foiler for a while when they were being built in Long Beach CA. Before the Hobie Cat Company became interested in them. It was my job to go out and break it. I was pretty successful for a while. Then as Greg Ketterman was able to get all the parts that were faulty redesigned I had a harder and harder time breaking things. He is very careful about design and durability.
It is an amazing craft. It is like taking off in an airplane when it changes from displacement to foiling mode. I had a speedo that read 40MPH and it was pegged most of the time. I think that he changed that to 50 later on.
There was no such thing as coming down off foils either for gybing or tacking if the wind was enough. It is actually easier on the boat as you are going through a gybe at faster than windspeed the whole way.
Later,
Dan
For Jennifer and Dean.
For Jennifer and Dean- Ive been trying to get you 2 together for this for 5 years, then show up with my surface piercing foiler rig too! We had a LONG thread on this subject whenb the boats were new, and had never met head to head. Now the BEST place is in North FLorida at Lake Santa Fe, where 2 Raves live already: Hollis and Doran Oster. Free place to stay overnite too. Deep lake with great wind (like today). However Doran has lost interest because of his A-cat. (Heh, Heh, Heh, my fault!).
PS: I broke my boat at Kelly Park on a sandbar.
So- like when?
Dean,
I have a good Prindle 19 hull I will give you for this project- really cheap!

Does 'give' have a different meaning in American English then? 
Interesting post about testing for Greg K! These boats are just about bulletproof. Most people assume them to be fragile but they have to be robust in order to easily withstand the forces present once they're out of the water.
Bug Man! Mary says, "hi".
Hotdamn! With the offer of a cheap P-19 hull (you got change for a twenty?) I'll have to put up or shut up! I think the Rave uses the same mast section as the P-19. First, I want to as-built the Rave frame onto a drawing. After that I would need to as-built p-19 hull. God, that would be pretty wouldn't it? I hope the final weight wouldn't kill the idea. With my amateur engineering I might end-up with a heavier boat with killer looks.
I love Lake Santa Fe. Big lake, gorgeous Florida cypress shoreline. (See the background in the photos on doranoster.com, click on "Getting It Up" for the foil uphauls that he designed.) Hollis and Doran might could be talked into getting out there for a while if Hollis hasn't sold his Rave. I know he had some lookers this spring but I think they cooled after considering the setup time involved. Doran still checks into the Windrider Yacht Club forum once in a while. Maybe I could drag Mike McGarry (Rave test pilot) up there, too, for a brainstorming session. Jennifer could have some fun and input but it would be a bit of a drive up to Gainesville. Jen could stay at our place in O-town if you wanted to make a pitstop overnight up and back.
I'll stay in touch. I'm sure I have your phone number and e-mail in my address book.

The only thing you might have to worry about hitting on Santa Fe would be the average....GATOR.
Dean: Give/cheap- means I need to be given a cheap ride on the P-19 rig when it is done. The P19 hull weighs about 60 pounds, gotta be less than the rotomolded Rave center hull. Also you better have a really skinny a** : the hull needs some widening to sit inside instead of on!
Hollis talked about replacing the Al center crossbar with CF, but it was all talk.
BTW- Hollis is moving to the wilderness - Bangor, Maine! Moose will be a big change for that Miami boy.
Anyway, Weight is the enemy of the hydrofoiler.
What has happened to Mr. Lord and his bicycle-style monohull hydrofoiler out of Orlando?

No, seriously, I gotta pay you SOMETHING for that hull. I needed to know it's weight, thanks. I honestly don't know how much my hull weighs but HDPE is dense. It's quite a process to take it off. I'm gonna call you this weekend.
I really hesitated on bringing up the idea of a new hull. It's a two-year-old idea. I need to talk to Dr. Bradfield before I go flying into marine software and Autocad. Dr. Sam may already have an alternative hull design that didn't make it to market for whatever reason but that may have been an improvement over the stock hull. He might sell me the plans if such a thing exists. It never hurts to ask. I wanted to give this idea some legs before we move. I had a short talk with Mike McG. and will talk to him again this weekend. Go here for the boring details in a post I made today: http:/
My Mom was small. I inherited her butt chromosomes. It does comes in handy. Mary's Mom wasn't small. (Just joking as always, Ma.)
I may be right behind Hollis. Canada is looking not so cold these days. We've made one scouting trip already and made reservations last night for another trip.
Dean, I just read your WindriderRave forum posts. Just compare the size of the relatively small Rave main and tiny jib with a big Prindle 19 sail and mast. I believe that there is absolutely no problem with P19 hull strength: I'm not talking about stupidly duct-taping a P19 hull under the existing rig, but why not just do it? You needn't change much of anything else, IMHO, except stabilize the rear end of the longer hull. Sitting on one place on top = good, hull-top **** = good?, scuttling around to manage all the strings and feet/rudders too = bad.
Now if you want to sail hydrofoils really well, you can simply get rid of the troublesome yellow plastic amas and even more unhydrodynamic center hull, by replacing the amas with 2 lovely, shapely P19 hulls! That's one on each side! Ooops, meddling again!
Well I'm off to the Wildcat now to zoom around with the other little A-cats this weekend, and Wild-Thing practice. We still have a breeze fron the backside of Rita. Enjoy your Cad-Cam sessions and odor of warm yaller polyethylene.
Nick,
You THA MAN! I'll be watching (and maybe bidding).
Thanks buddy!
Greg
