Trying to disscuss design on both forums has become a waste .
Back to just posting custom boards .
Greg might be saying that the fins create lift that pushes the back of the board up. Can’t say if the fins on other boards do the same. Airplane wings would create a lift that is pushing against the flat side of the wing. That would not be pushing the board up.
Interestingly. Greg let us use a twin fin way back and I could not get that board to work for me, it felt too stiff. I think I was standing too far up on that board. Same thing for other boards we have from Greg that are longer. I must be standing too far up to get the magic going. With the fishes we have to put our back foot right over the fin cluster, then the magic starts.
I like the C6, that looks interesting.
One thing to look out for with Greg’s fins… that trailing edge is sharp. You will slice your finger or toe if you are not careful. I took some 400 grit and lightly sanded the edge after slicing my hand.
The first time I paddled out on one of his boards I sliced my ankle right on paddle out. I had fun anyway!
Party over.
Everyone out of the pool.
LOL
I am on blood thinners, so when I get a bad cut in the water it won’t stop bleeding. I sliced an area along the side of my finger close to the nail and it wouldn’t stop bleeding, so I had to go in. I was bummed because it was a really good day. I still love my Griffins and always get blown away when I use them. Riding my brother’s 6-2 x 21 5-fin fish these days because I’m 10 lbs heavier than when I got my 6 x 20 made. I have a Griffin longboard that has not seen the water yet, a standard HPLB thruster. Maybe this summer, I’ll give it a try. Had a 6-8 thruster for a while, but gave it back to my brother, and I have a 6-5 5-fin modfish that I haven’t used for a while. Funny the Griffins are the only boards I’ve kept inside the house.
Greg people don’t understand what you’re trying to say. Just gotta explain things a little better then they may get it. Anyone who has used one of your boards knows there’s something special there. Even the guys riding the longboards you were making at T&C will tell say they were good boards. Craig admits you made great boards too, though he may not tell you that.
Secret Sauce discussions are daunting …
first of all
I want one of each of your designs before you decide to retire and leave for the mainland
a twinzer variant of that new inline thruster design, a 5 fin hp longboard, and an epoxy replacement of my fish my brother “inherited”.
unfortunately I am broken and will be broken for some time so I can only dream for now
comes with age I guess.
Anyway seems like everyone uses the whole outside inside foil business like they do with airplane wings meaning that because the flow is faster off the curved surface it creates low pressure and lift allowing winged craft to fly.
unfortunately like Greg says I don’t tink fins on a sirfboard in heavily viscous fluids work the same.
seems like to me most of the rail and tail surface are acting as the main thrust source with the fins as complimentary components. Rarely do you see a board running flat in almost all cases a rail in engaged creating flow driven across the board at some angle. The interaction of this flow exiting the bottom surface and engaging the surface of a fin is what most likely creates the forward drive we usually solely attribute to fins. with most side fins both toed in and canted unlike a single fin its impossible to imagine the fin creating lift flowing through the water like an airplane wing but more like the fin creating drive and thrust as it interacts with the flow of the water coming off the “bottom” of the board.
most of the white haired shapers I’ve met seem to understand the importance of this waterflow release relationship to a board’s performance. They all seem facinated with the what the water wants to do when it comes to their designs.
but then I don’t know sh*t
I just buy 'em, ride 'em, and sometimes make 'em when I have the time.
I’m still scratching my head over all the surfers and surfrider organizations complaining about the styrene in plastic plates and bags to get rid of them and then who drool over the don’t last over a year latest and greatest surf toy design. When i think about all the cans of styrene, acetone, denatured aclcohol, catalyst, naptha, and resin I need to make just one of these things I shake my head at what’s going on lately.

I love’d those T&C HPLB’s my I had a perfect 9"0 one Greg made…it was about 2 5/8 thick. Great board…but I destroyed it.
