Real Info PLEASE

Could someone please explain the correlation of foil and rocker?

Could someone please explain the correlation of foil and rocker Foil is the thickness flow as it graduates from nose to the thickest point. Then from the thickest point to the tail. That entire thickness flow is foil. Rocker is the curve that the bottom has from nose to tail. Pay attention to the curve behind the nose curve and in front of the fin(s). Thats what you pay for. Ask Mr. Spitzer. He’ll back me up. We had a test on this at school today. Can’t wait for the Diamond tail test … have fun

I know what rocker is and I know what foil is but what I’m asking is explaination of the relationship of the two in design and function while surfing (not talking xtra float for paddling). I mean, over 9’ of longboard I’ve got alot of area to choose to put the max thickness. Does it matter where it is in relation to the rocker or just the rider? Would a couple of inches forward or back matter? Is the max thickness always the apex of the rocker therefore dictating the rocker? I’m gettin confused and having a hard time verbalizing my question, but it’s an honest to goodness design question and if you get it I’d appreciate an honest to goodness explaination.

Sure it matters! are you a big guy, or are you Slim. Or are you a big guy and slim. An inch matters everywhere, ask her … have fun

Try to look at it as defining the “sweet spot”. You can define that spot with rocker or foil, but a great board combines the two. In general, foil dictates where the balance point (trim) is while standing. That is the board will float (or sink) equally with you standing on that point. If that point corresponds with the curvier part of the rocker you will have made the turning sweet spot correspond with the trim spot. What mucks up the whole picture is the length of the board, outline, rail type, fin(s) location and even bottom contour. So it’s all a matter of compromise. And that’s also why there is no “perfect” board. If this is your first stick, put the thickest spot in the middle. But it should be so subtle and smooth that you really couldn’t tell exactly where it is. Also you can steal it from the blank…the guys that shape the plugs have been shaping for decades and know their stuff. Newbs
