Of Wings and Twinzers- NOT a hijack!

Asked this before on another thread- Sorry about that; I always seem to think of this stuff while reading other people’s questions. Never got a direct answer on that thread, but I respect those who stuck to the main point.

Anyway, how does a HARD single wing affect takeoff and down-the-line speed (specifically on a Lis-style template)?

I always assumed that it allows water to release off the same width and hard edge, with the same straight rail line, as if the width had been carried all the way aft. This allows the board to keep the incredible squirty speed of the wide-tailed fish, while pulling in the last 12" or so of tail to add holding power on steeper faces and easier/tighter rail-to-rail turning from the tail.

Is this right?

See attached PDFs for a general comparison- “de-winged” outline comes from an old G&S board my uncle refuses to sell me. Have ridden it and like it a lot (squirts away like a bat out of hell-fun, fun), but since he won’t sell me the original, I’m tryingto decide if I should modify it a little or just have my shaper clone it.

Also, what would happen if I were to make a twinzer out of it, rather than keep the twin keels? It might make it more versatile for the east coast, but I love that blast-off speed feeling on lined-up days, though. I would hate to lose that…

By the way, “Beach Plum” is a reference to the name of my uncle’s store, where this board hangs from the rafters when nobody’s on it. It has nothing to do with the board itself. Thought I’d toss that out there for you historians who were going to scoff and reply with derision that G&S made no such model, insinuating that it must therefore be a Chinese sweatshop popout shaped by a toothless 10-year-old landlocked kook and shipped in a container of fake early-'70s wall hangers for pasty dentists from Des Moines, with which the boards would serve as props to regale patients with stories of thier exploits as a HERO of the Banzai Pipeline…

Nobody? Come on, this stuff CAN’T be that played-out. Nobody has any new input?
