Steve and Dave Clarks Unidentified Foiling Object

[P Flados]

Jolly,

I did a couple of rudder experiments similar to yours, but never got anything to work worth a darn. 

I am pretty sure I can relate to your situation.   

One of my closer places to sail involved working up or down inland waterways with lots of shallows on the edges.  Sailing in water with an average depth of 18" is doable with the UFO rudder down for for about 15" of bite, but you just have to put up with hitting bottom if you run across a shallow spot.   Stay slow in the shallows to avoid bending the pushrod (I made a work around for this).  I felt it was important to jump out of the boat quick when the rudder did start dragging to minimize rudder damage risk.  Eventually I pretty much just gave up sailing at that location due to my frustration.

 A "kick up" shallow water rudder "add on" would have real value for some users.

Who's the owner of the UFO in Clearwater FL?

We're here for practice on a different boat, but there's times in between and I'd love to talk with the UFO owner.

I'hve some salt water in my UFO's hull because I forgot to close one of the 2 caps....
Do you think it should be better to rinse with clear water?

can you shot pics of the covers for sale? how easy is it to hull cover? I hate hassles. a couple seconds? or minutes? Is there a cover for the mast while installed on hulls? shrouds would limit this? or a way around it? Trying to keep UV off a UFO resting on the beach all day.
never mind pics I see them in your link. (cover can't be used with mast in place?)

Here are some photos ; hole threaded, knob and stainless steel screw, plastic tip

I tapped my hole
I could not find the plastic foot? I used rubber.
Not in the water yet - but it appeared to hold the rudder in place with very little tension! = )

my knob/rubber tip. 2nd photo - TAPPING... and I made a beach SLIPWAY instead of the wheels. Looking for the last amount of hassle.

Rojoyinc, that seems to be OK ! and good idea for your beach slipway !

We have had almost zero contacts about our UFO and have been trying to sell it for a few months. Anyone have any advice or tips? Appreciate the help.

Martin. There is a donated UFO at the Clearwater sailing center leaning against there fence sying a slow death. Not sure alll the parts are there but I bet the center would be open to you inspecting it to see

When I looked it was pretty complete, perhaps missing a tiller extension. If the sail is in a locker that's all we need to make it go.

Do you know anyone there, or would you vouch for me next time i get to Clearwater? I might get a cover for it or even org a demo day if the winds are favorable.

 

[Ledge]

You can just talk to the people at the sailing center. The boat was donated to the center. They told me some kids played around with it but didn’t have much luck. Kids there are foiling on windsurfers but maybe they just need a demo.

By the way, I plan to be in Clearwater from Jan 15 to Feb 15 with my UFO. Maybe a good place to have a UFO event.

Hi, new newbie question: unless the rudder is 100% down, the boom catches on the rudder. Sometimes this causes a capsize during the launch or wrap up phase close to shore. I've tried adjusting outhaul, shroud tension, etc. but can't figure out what to adjust to avoid this. Any suggestions?

That doesn't sound right. Are you setting the right tensions on the _cunningham_? This should pull the clew down significantly.

 

[Rojoyinc]

Update parts are here. I could use some help. I think I can figure out the dial/housing for rudder rake slop. (just screw it in).

But 1.
Two things look like mast rotation shims? to add slip? will be nice as it SQUEEKS as is.
Just put both on mast before putting mast in hulls?

and 2.
Front foil "pin" hold downs - do I just swap out old ones (screws align? I hope).
remove 4 screws - replace 4 screws? would be easy.


and 3. To black bushings? I assume around rudder area? They replace original white ones?
Spreader looks scarey - Dave said drill stainless spreader plate rivets. (ok).
Then just glue this one in same place? (move over parts off stainless one)) anyone have video/photos of doing this?
And of course 4. that plate? that looks like it replaces or adds to the rudder foil/mast area? (HAS TEAR DROP CUT OUT). cut off old and add? or better yet I'm hoping I can add it to one that is already installed. What is this for? If I knew what each update "solved" it would help me figure out how to use them.

lastly 5. A piece of what seems like a mast joiner? 20" or so of thin cf tube? and then a small THICK cf ring with some lose cb - assuming that works into the glue. But where how?


Nylon screw - I already solved with knob and metal thread.

 

[martin 'hoff]

@Rojoyinc - there's an online doc (ask Fulcrum) that explains it all...

From description and pic, looks like you got CF "sleeve" which might be a hint that they'll suggest you reinforce the boom forks or is just a gift / extra. If gift, extra, it is amazeballs to repair a broken tiller extension, tiller, etc (note!!! it's not the only ingredient, but it's the hardest-to-source ingredient).

For spreader bracket, make damn sure you use the right glue and procedure. Lots of pressure on that bonding point.

I got your email an hour ago. Gimmie a hot second to reply.

Note to the viewing public: There's a shortage of black G10 globally. Hence the nude G10 pictured in some parts above. Structurally identical. Cosmetically different.

Check your rudder AoA as well. If you've got the whole system desperately trying not to foil it might be swinging the strut forward.

LINK? i googled all over for it and nothing.

all the links should be in a post on here that is either in it's own thread title or pasted in this group in place of prominence.

How do I check AoA on the ufo. the rear foil would be parallel to what on the hull? Bottoms of hulls?
I've been up but before I get up the rear seems to be dragging. And with the slop I had my AoA was changing
I've been looking at the update manual. At first I was puzzled but I'm getting it by reading over and over.
The carbon tube you send is the INNER reinforcement. The ring I think is the buttress (with some cf to wrap around the buttress.
not quite clear on mast base filet. (carbon wrapped too?)
And how to use the 2 delrin spacers - are those for mast rotation?
I didn't like how it had been squeaking. (friction) I suspect just put both on before inserting the mast in the decK?
The two should slide nicely. I've not found step by step instructions for the rudder frame (top?) replacement. That one kinda scares me.
but it might be more clear when I get the parts to the boat and compare my boat to your pictures.

Dave is too nice to say, but that document isn't formally public. That's why I hinted "ask Fulcrum" instead of "ask google".

How to check AoA on UFO rudder? The delrin spacers? That's in the unofficial guide.

Carbon tubes and repair/reinforcement bits - in the guide by Fulcrum. There might be a newer version. You know who to ask. For those updates/upgrades/reinforcement, don't get creative, don't color outside the lines. Do them by the book, or sh*t will break – I've been test pilot for some of those and everytime I didn't follow instructions to a T... it ended up in tears.
