Can someone explain the science behind this design please....

New guy here from Myrtle Beach, SC.  Long time reader first time poster.  I am moving soon, and will be starting my own board build soon thanks to the knowledge I have gained from this site, so thank you!!!

I bought this board for cheap from a surf shop closing down in North Myrtle Beach, SC.  I figured if I didn’t like it I could easily sell it for what I paid or more.  It is a very light eps/epoxy build.  I have only taken it out once, in some true knee high crap.  I can definately feel some lift, and it is a very nice paddler.  I couldn’t get much speed, but it literally was knee high.  I am 6’ and weight 210lbs. 

It reminds me alot of a buddies’ Lost RV, but with the extreme concaves.  Under the belly, the board measures about 1/2" of concave on the side channels and 1/4" at the stringer.  The concave starts about a foot from the nose goes deepest into the belly, and fades to a V in the tail.  The rails for the most part are pretty thin and i’d say 60/40 in the belly to a 80/20 in the tail. 

From what I have always read about deep concaves I’d say this board wouldn’t work well, but a combo of things intrigued me into trying it such as the width helping with stability, wide winged tail. 

What would your thoughts be on this at first glance?  I thought this guy really went out on a limb here with this design, and am hoping for some nicer surf to try it out in soon.  Unfortunately, the forecast isn’t looking too good.

Thanks!






A couple more pics…


Last one, thanks again. 

Just an update, the board rocks.  A friend of mine who is a better surfer than me says it’s the fastest board he’s ever ridden.  I agree with him, it GOES!  It really turns well when you get over the fins.  Nobody cares but figured I’d update ; )

Can’t find “follow” button but this should work. 

nice looking board!

You’re right!  No one cares. It’s got nothing to do with concave, Vee etc.  It’s the paint Job that makes that board go fast.  That jello and blue stuff that’s going on there.

looks rad, i have a heap of theories about why the board would be good, low rocker, easy speed, nice cocaves for drive, stepping the tail in multiple tomes to creat rail pivot points and less area in the tail.

 i could go on but im no expert so its probably all wrong.

i recomend you got to you tube and watch a bunch of shred show reviews, he actually expains some of those things pretty clearly.

 

Bottom looks pretty “bonzerish” to me. Deep concave = straighter rocker through that part of the board than the rails. Straigher rocker, less curve generally means more speed.

Thanks for the comments!  The main thing I guess I am trying to bring up is that I have never seen a board on a rack in a shop with all these extreme concaves or v’s.  Most of the time in boards they are very subtle, so this really caught my attention.

It’s all about that color scheme… DUH!

 

The pointy bits make it faster

It looks to my amateur board builder eyes like you have a board that is simply a good combination of elements put together intelligently.  And you’re the right size for the board’s dimensions and you’re riding it in the conditions for which it was intended. 

In other words, you made a good choice by picking that thing up.  Good on ya.

My hunch is that stock boards you typically see on the rack have more subtle concaves so they don’t scare away customers due to having “extreme” features.

Kudos Newschool.  Nice old-school Sways response…
