All dressed up and ready to fly...I will prolly Monster Paint, or add EVA pad strips, to areas that may need it, once I have some time on it...there are really four sports going on with it...SUP...SUPfoiling...windSUP...& windfoiling...as close as I've come to designing the ultimate one design...;-)

Gracias jrandy...
I just added a couple of EVA pad strips to the tail...the pads that I designed for my other boards didn't quite fit this application...so, I kinda cobbled together something functional...but, not necessarily my first choice...it's growing on me...and, I predict even more so...once I install the foil and get it flying...;-)

Right on!  I look forward to the flight report.  I'm guessing you already have a flight plan, care to share where you plan surf it?

I ask because I have yet to think of a good spot to SUS foil in my area.
Aloha, I welcome and appreciate all responses of positivity and good feeling.

Been bodging up a lower profile mast today to test some different foils this one is a ply core with carbon and glass.

Man, you're reading my mind. I've been thinking of making a mast with tail and wing mounts for testing different wings etc.

I'm also thinking of mounting it to a thin plywood sheet that I could tape onto a board at different places like Piros did. Not perfect, but probably a good way to learn a lot about foils and how they work with different boards.

Still just making notes and such but I'm curious about a way to quickly mock things up.

I wouldn't worrey about the board to much to start with, just use something that will paddle fairly fast. The  foil adds loads of stability.

I just got this back together and off to test it later, if nothing it should have a lot less drag.

I hear you Clay. There only a few breaks in the kelp the entire length of Pleasure Point.

I'm thinking high tide down at the beaches just south of Moss Landing. It starts to break way outside and backs off at high tide leaving plenty of room to experiment.

Since you'll probably spent a fair amount of time in the water falling off at first, you might want to check https://www.dorsalwatch.com/report/

Those are the breaks, when a big swell hits and it's good, but not breaking when the tide is high. Way outside, no one inside because of the big rollers.

So these foils were kite foils and I took them out today, for initial testing they do not seam to provide much lift at paddleing speeds, it tock a fairly good size wave to get out the water and it felt even more unstable than my own which doesn't surprise me with the ached tak so I think these are out the window and time to try some other foils.

They look pretty small, especially the rear foil. I'd guess about 120# of lift at 6mph. That's a total swag, but that's how they look to me. I'm constantly surprised how the calculations come out though. Wings don't have to be very big in water.

According to the company I got them off they are fairly large for a kite foil I belive they went smaller still after. I actually ended up cuting mine down to the same size but used a flat bottom foil were as this has a fairly symmetrical foil though so not sure if that needs to change or not as odviosly there is two different pricapals.

Wow, I guess my initial calculations weren't that far off. Everything keeps looking too small to me, so I raised the weight.
