Half way thru doing a longboard I wondered what would the effect be of taking the rails r-e-a-l-l-y thin, like 9 mm.
So as a test board I did a paipo thats 3 in thick thru the centre and the rails are 9 mm.

What do you think the performance will be ?
I was thinking it will make it faster because theres less rail volume pushing thru the water.
Hey Foils...same same but different -
My latest personal board. I was thinking a lot of things with this one, not all of which I've rationalised. -
Tail foil very fine and down-railed but with a chunky raised centre arch-bar, which'l keep some good volume.
So lets glass 'em and ride 'em...

...this is the bottom of a finless board? Can you tell us more about it, and about the rails? Looks interesting.
Hey Josh, how do those contours affect flex? I get having foam in the middle and tapering down to this rails. I guess my instinct would be to knock off the bumps (the ones 6 inches in from the rail) and make a smooth gradual dome. But I guess doing that lose some volume. But back to my roginal question- which deck shape is stiffer?
interesting work guys...dunno bout the arch bar , no good for me , I have ultra flat feet..but like the different approaches....bit of mini-simmons influence there Surfoils ??? I guess its an extreme version of a flat deck really...and they work well, good way to maintain volume but still have a fine rail to still give a responsive feel....keen to see these come to life.....
Out of my small collection (and already posted here), a Greek board that he made around 1969:
Ive built two of them. One for me and one for a friend. Both boards ride amazing, the design allows the board to carry more thicjness (float) while still providing high performance rails. Im 6' and weigh 215 lbs and ride a 6', 20 wide board, I just took it to Hermosa and rode it on overhead barreling fast beach break waves and it was amazing. Here is a pic of the 5'10" one I made for a guy who raves about its performance.

Interesting too see that the earlier board like The Greeks one, is a rounded style, whereas the modern designs like Lovinlife's are more 'digital' with sharper lines and angles.
When will we go to minimalist kiteboard rails and then the 'lovingly contoured rail' becomes an old skool relic ?
Speedneedle, the glass on the convex arch bar would add rigidity to the board..
and the Arch Bar concept makes me think what about a board where all the volume is in an enlarged foam arch bar and the hull is just a 1/2 think compsand sheet of honeycomb,epoxy and Innegra ? Taking design into greater specialising.
Like Lovinlifes or your design, just taken further ?

Its amazing how precedents pop up...that Greek...
And Pridmore, yep, I have high-arches. You'd be better with a concave than a bar.
Here's anothery -
