square rails

what would a board go like if it had a good rocker,foil,outline shape etc but had square rails ie all flats no curves

any theorys?

square peg in a round hole…maybe if you do your homework.

well if the square peg is small enough it does work

thank you for your reply

i have done a lot of home work

what i am trying to gauge from this is many fold

theorys,existing knowledge,overiding mind set

swaypeoples want to considar out side the box

well if were just going to guess and you really want to know make the board and find out (but i don’t think it will work)

Never built or ridden one, but I predict lots and lots of rail digging, catching, and hanging up. Any examples in nature of square sided fish etc.? Mike

They do’nt work. I tried a square railer years ago,I just lightly rounded the corners so the glass would fold around.

Paddled ok. except when I turned the board kept going straight ahead!! Big failure but someone who new nothing bought it ( I feel sorry about that now)

square rails ,

square [or round] fin ,

[and a nice pointy triangle head … ]

I want PHOTOS , please !!

cheers Eky , good luck with the [?alan parsons?] project !

That’s funny. You’re a sharp cookie, Chip.

what about if the square rails had chines

what does every one think would happen then

now we are down to the difference between a radius and a flat

could ,would the water know the difference

as a referance to this look at a ram air parachute the LE is a great big hole but the air flow sees it as a nicely formed LE

Don’t most older (maybe some current) bodyboards have what could be described as hard chine rails?

Better ! Your getting there,just think it out.

Bob McTavish did an interview a few years back where he was discussing the benefits of squared off tails. (not the whole board, though)

His observation was that the squared rail in the tail section allowed for “dry deck” turns, because there was no wrapping of water around the rail. The water would hit that sharp corner, then break away cleanly. The result was a high-planing tail, under the rear foot, in the fin-control area.

If it was on the whole board, I don’t know. I guess the performance characteristics would depend alot on rocker and bottom contours. But it seems to me it would be hard to make a good nose-rider: not enough water wrapping around the rails to hold the tail down. Why don’t you try one? Doug

There used to be this guy CP shaping boards in Haulover Beach who did some pretty damn square rails on his thrusters. When I was a grom he was doing them for some of my buddies, and they really loved them. Can’t say i ever tried one myself tho.

i reckon it would work sweet as

body boards work better with chines cuz they are faster and better release on spini moves

also when you bury then they actually have good hold as well

chines on a surfboard if well designed

would be fun

maye make the fins smaller and the board shorter with flater rocker

i actaually cant tell the difference between boards all that much to be honest

most stuff works in certain conditions

so much is in the mind

I remember an article in one of the aussi longboard mags about a test ride on an old 7’ ish ply board with square rails and it worked better than what everyone throught…

Surfline (NZ) longboards also do a board with a chine rail (chamfered running from the nose back about 2/3), I think the theory is that it has the volume during paddling but when up on the plane its riding on a smaller/thinner bottom shape, people ridding them where doing great so it must work…

One sunova I have seen has a very squareish hard rail all the way thru as burt has tried to shape in a rail with 15-20mm of balsa while keeping the volume in the deck all the way out to the rail, and again the guy that rode it luved it…

Yep i reckon they would work, might take a bit to get the handle on them and they may not be as forgiving as a more conventional rounded rail…But who knows until you ride one… thats the thing about surfing, different boards suit different blokes…

cheers

how about a rail that has a long, hollow barrel in it running through it… Intake and exhaust through the middle third. A turbo rail. Normal rail in the tail and nose, so it would be non-functional during turns. But it would suck water trimming and, on a longboard, maybe give you the noserides of your life. It would be a delicate operation, but I wonder what it would do if you carved it out of a normal rail, or even a square rail???

Good morning,

Squared rails? No. ekimsbas, if you play with the letters, could actually spell mikesabs. Check archival footage accordingly.

Ride on,
