If you are comfortable with those assumptions then I can comment, otherwise I can't. :o Go for it. You have got me curious! So.. under fairly steady state conditions, while under kite power, and edging on a typical reach/tack, the waterline under the board looks like the photo below. The board is p...

The trick is to put a ferrous metal in the insert, and then use a strong rare-earth (neodynium) magnet to find the metal.
The typical magnet tape they sell on places like junksupply are too weak to find easily.

The I-beam press will allow you to shape the wood and ski building forums have great info on using them. If you resin infuse the laminates you have time to set the dry fabric (spray adhesive works great) and see if the vac is steady before adding resin. Infusion is also great since you can stop at ...

I am not impressed in any way I must say, so hope it is thrilling and fun if it is the "thing"

Yeah I feel the same way about those weird hydrofoil boards

Maybe read up on Savitsky planing hull theory if you are really interested in answers. Any chance you could give some insight or a primer of what to expect as far as the relationship of Savitsky theory's and flat planing hulls engaged at an angle (edged) with relatively continuous rocker and variab...

Nothing wrong with negative rocker (camber) in the middle of the board. You'll find this happens with very flexible boards by default.
The net effect is the center of lift is moved more towards the rear foot.

Drop in a small ball bearing, cover with wax.
You can find the ball bearing with a magnet if you use SS316 inserts.
Drill out the laminate and use the same magnet to remove the ball bearing.

I think the more general question is, do people understand their equipment and how to use it. It's easy to get caught up in the terminology and assume something works a certain way. I'd rather know that if I connect my leash to something that it's going to have the desired effect, as opposed to figu...

Ok I've moved the front fin 20mm further towards the footpade keeping 35mm from the edge. What do you think of the rocker values and concave? 15mm too much? i'm wanting a bit of flex in the nose and tail. But at the same time i want as flatter waterline as possible for efficiency. I've thought abou...
