Hi…so i shaped this, and i am interested to learn or hear any pointers on what fins or placement to maximize speed and drive on this shape. Ive learned all this stuff from swaylocks, and it sinks in gradually but it would take lifetimes to learn it all and thats not gonna happen for me. Up until a couple years ago i never thought about design factors, and through my twenties all i knew was some boards i liked and some i didnt, but i never thought about why i preferred some over others. I have a grandmother who doesnt get it, she said how many surfboards do you need? But my dad gets it, said he always wanted to build a boat, and he probably wouldnt stop at one. I said yea cuz you realize what could be improved from the first one, and then yer on a mission. An overall thing i learned from swaylocks is the tradeoff of elements- increase x at the cost of decrease in y. The whole package is a balance of elements ideally tailored to acheive desired effects. Ok well this is just trying a shape that is not common to what ive been riding the last couple years, which is mostly short wide twins and occasionally my wrv thruster or another overbuilt singlefin i made. Mostly rhode island, occasionally cape, trips south, maybe one day afford to travel more again. So this is seven foot ten, 15 1/2 N, 22 1/4 Mid, 14 1/4 T. Influenced by the egg thread and the ‘increase tail rocker to prevent pearling’ thread, among others. Tail rocker is 2 3/4 but its kicked, its 1 1/2 a foot up from tail. and nose, i lost some, gonna wieght it after lam, will be four inches, 1 3/4 a foot back from nose. Rails came out quite full on this one. I’m hoping for smooth turning with the rounded pin and tail kick and quarter inch of v in the back third of the board, but since these are drag elements combined with fat (tucked, nose to tail) rails,i wonder what i can do with fins to counteract potential loss of speed and drive. Or just go with a single and milk it! thanks, D
different template fins, increased rocker, different bottom contours and tail planshapes will all alter the boards performance, it is not as simple as picking a fin set up, so many variables and each one needs to be considered to achieve the end result you are after....I do have a few good boards with the McKee, if ya interested, check em out at www.moresurfboards.com and go to the Quadfather section...not meant to be an add , sorry guys....
I would do a 10.5" fin box center + Quad set up side. Use the McKee fin placement table for numbers - http://www.mckeesurf.com/brucemckee/multisystem.htm
Then you have every option-
Single fin
2+1 (such as a 7.5" cutaway fin with some small side bite fins in the front position)
Thruster (Thruster size box fin and front side fins)
Quad
even some 5 fin configuration
Why limit yourself and your board when you could have a board with so many options. Just make sure your fin box is far enough back to have a 4.5" fin in the proper position for a thruster (again the McKee tables above will give you a good idea of where…look over his site for other info)
Mckee quad with KS2.1 fronts, G1000 rears
Ok thanks fellows, i am pretty misinformed on quads, didnt consider that, thought those were a config best used on wider tails, shows how much i know…looks like my pics didnt post but i guess the dimensions were enough to get feedback. Billy the multibox arrangement sounds ideal but i think the tail on this is too thin for a centerbox far back. Pridmore that sounds pretty specific, reckon youve got a magic board with them on it…ok i gotta do some homework on those and mckee config. Time to get some glass!
I'm glad someone is picking up the idea that design elements are interrelated. Good on you. That outline/shape looks like it came out nice. But it's probably best to have a fin plan before you shape.
Since it's more or less a classic egg, a single fin is going to give you the most authentic egg experience. It also depends on how you want to surf it; a single is going to be smooth and free in the pocket but slow off the top and cutting back. Multi-fin if you want to surf more aggresively; McKee quad will give you long fast bottom turns, trifin will come off the top quicker.
Putting a lot of boxes back there gives you options, but there's a trade-off for that too (weight).
mate i would go for mikes advice or ask reverb

Yes…after i read Mike’s post i didnt want to bump this again because i can be long winded but what he said went along with what i was thinking in the first place, so i will stick with a single for it. I just ordered a stock 9" fin from greenlight, try that for now, also got some basic quads to try on the other thing i got shaped. So many variables at play, best to try and see what i like. Yea pridmore i have checked out yer site before, like what i see…and nice sims going on, both you guys
