How deep is your board?

In Weymouth, Peter talked of sailing in a vacuum - the problems mothies have when there's no one else nearby. I'm not exactly in a vacuum since the Annapolis crowd is 4 hours away, but it is rough when there's not another boat nearby to compare. The problems are compounded when you're a home builder.

My new strut is about 4 inches shorter than my old one. How this compares with a "standard" strut is unknown to me. Would someone with a BR or Prowler or M2 take the time to measure the distance along the leading edge of their board from the bottom of the hull to the top of the horizontal? What is optimum? Aside from having to wade out much deeper to launch, would an extra long board have any disadvantage? or advantage?

Many answers will come with my gen3 FC board. Until then I'm still working on Plan C. No sailing today (drizzle and light winds kept me ashore) but I did get a chance to fill pinholes and fair the new strut. Wand, cable, control rod and flap all seem to be working well. Tomorrow's forecast is for some breeze so I'll see then how it turned out.

Oh yeah, my distance is a tad over 36 inches (or about 93 cm.)

Here’s Three Dog Night



One, by Harry Nilsson (1967)

One is the loneliest number that you'll ever do
Two can be as bad as one
It's the loneliest number since the number one

No is the saddest experience you'll ever know
Yes, it's the saddest experience you'll ever know
`Cause one is the loneliest number that you'll ever do
One is the loneliest number, worse than two

It's just no good anymore since she went away
Now I spend my time just making rhymes of yesterday

One is the loneliest, number one is the loneliest
Number one is the loneliest number that you'll ever do
One is the loneliest, one is the loneliest
One is the loneliest number that you'll ever do
It's just no good anymore since she went away
(Number) One is the loneliest
(Number) One is the loneliest
(Number) One is the loneliest number that you'll ever do
(Number) One is the loneliest
(Number) One is the loneliest
(Number) One is the loneliest number that you'll ever do

Joe,
My Illet CB in the old hungry tiger hull extended 950 below the hull. I think this is pretty typical.
My new boat has the foil 980 below the hull.
Rudder foil was 880 on the old boat which was probably too short, and its 1100 on the new boat which may be too deep but I know its not in the wake of the main foil.

From one vacuum to another...

Mach 2 has longer foils (15cm I think). The fashion seems to be long foils and fly as high as you can without crashing. Rudder tips sometimes breaking the surface upwind seams to be in fashion, but not sure how you do this without crashing. Cutting off rudder tips will probably be the next fashion, and could be a trend started by Adam.

I have no exact data or explanation for the fashion but hope this helps a bit.
