I would
like the shapers of sway locks to help me design and build my self a surf board
6 ft long that rockets down the line on my local 3 to 4 ft point break so fast
that my ears flap!
I want you
to contribute by advising me with dimensions fin size and shape finish glassing
weight etc and theory.
I don’t care
too much for maneuverability just crazy out of control speed.
I plan on
starting the project and posting photos two weeks from [today 11/1/2012].
My height
is 6’5’’ weight is 100kg and a very fit handy surfer with 25 years of experience.
I wonder if
anyone has made and ridden anything full size like that recently, surpose you
just set the rail and hold tight for as long as you can in a straight line.
The photo
on the link was a single fin, never thought Simmons was into them as well.
I have a
photo in a book of a Tom Blake board twin fin with a deep concave nose to tail
which might work up a fair bit of speed that looks similar.IAppreciate all your
input thanks.
The designs varied a bit from board to board. Some were single fins, some twin fins. Some were kind of pointy at the nose, some more rounded. I've seen a couple that were at least 10 feet long and roughly 24" wide. I'd 'guesstimate' the tail width at 20"-21", tailblock at 18" or so and nose at around 18"-20". Not sure where you're located - the Surfing Heritage Museum has at least one in there. One sold at auction a couple of years back. I think Roger Kelly posted some pics somewhere on Swaylocks.
I would think that weight played a big part in maintaining momentum once the rider got one going at full speed. In a 3-4' point wave, that might have played a huge role.
Hard to say if a guy on a shortboard squirting a radical vertical maneuver generates a quicker burst of speed for a moment than a huge board in full trim heading down the line. I guess that point will always be argued.
My vote is for a big longboard if any sort of average speed is measured over distance via GPS or radar gun.
What were
the dimentions of those old balsa twin fins ? [you didn’t have my full attention when
I first read your post I was teasing the cat at the same time] I once saw
footage of an old board like that in an old fizzy grainy movie
I can't really make any claims on that although my bellyboard does seem pretty fast either with FCS curved fins or a hoop fin. The dimensions are 5'10" X 24" with 22" tail and 19" tailblock. The tail is flat with little rocker. The rails are kind of a flat/hourglass kind of shape that might help generate speed.
The thickness is aft of center as that is where my weight seems concentrated. The deck is concaved.
In any case, I'm happy to provide any other details if anyone is interested. The thing is trashed - will likely either get taken to the landfill or stripped and reshaped at some point. I think there's enough foam left to get something fun out of it.
If you can get around the concept of vertical surfing and cutbacks, those big heavy boards with flat rockers, wide ass tails, and twin keels appear to have been hauling ass and couldn't be stopped.
Surfed it
on the same point break as mentioned yesterday, came off at a flat out velocity
involuntary yousing my face to slow down felt like an eye wash with a fire
hose. SO MUCH FUN !
I think a
wide round nose with kind of flipped up rails would help with getting a straighter
rail curve and have seen a couple of fishes with a sort of square nose to make the
rail straighter still, am I on the right track ?
