Has anyone out there experimented with a parabolic outline on a surfboard built with conventional surfboard materials? If so, what were the results?

…you mean like a swizzler…try a stinger.Herb Just cut out a new sting today, 6’9" Sting Pin, seen a lot of swallows, but I haven’t seen one with a pin in about 20 years. I went 11.5 nose, 20.25 wide, and 13.5 tail. I put the .5" stings at 21" forward of the the tail. I used the 6’9A blank. Think I’ll keep it for myself, undecided yet on whether to install long box on center, but that 6’9A is just crying out for a retro designed surfboard. Wish the board archive was up and runnin. Aloha UNDERGROUND

Aloha UNDERGROUND I found a few OLD arse blanks in my nieghbors garage and one is a sub 5’ stinger. It’s a mini version of a Aipa Stinger. I guy saw it in my shop and begged me to glass it. He’s real good, so I figure what the hey! I’m going to be on here soon, trying to figure out fins. It has real pronounced wings and a deep swallow. colin

Aloha UNDERGROUND hey underground…I just got an order for a retro Sting…I was lucky to find an original AIPA Sting about the same length as yours. This is going to be a fun project. Only this guy wants his about 8 ft. long. I am trying to council the brudda that this aint Hawaii (Florida) but he’s almost as vapor locked into the 70’s as me. I’m thinkin 7’1"0 Max. JC
Has anyone out there experimented with a parabolic outline on a surfboard > built with conventional surfboard materials? If so, what were the results? This was what I used for my daughters outlines on their first boards. I wanted a ouline that couldn’t cause injuries. Roy Underhill, who runs the Williamsburg, Virginia Historical woodwright shop, demonstrated how to draw a perfect oval. It used two trammel points along a line, a variable distance apart, with a lenght of twine tied into a loop longer than the 2 points, a pencil is inserted inside the loop and moved around the tensed twine, completing an oval as it follows the orbit around the 2 points. The distance apart of the 2 points and the lenght of the loop determine the shape and lenght of the oval. A third point can be added even with one of the other points and create a “wide point” at either end. I hope this doesn’t sound too confusing but it is rather simple once seen.
I’ve seen that done - a perfect parabola! The true double ender egg.
I’ve seen that done - a perfect parabola! The true double ender egg. Jim & John, I was over at DaGooch’s house night before last. He showed me an M10 – 5’0"x20" thruster he’s been surfin’ (the guy’s 6’3"-- it’s amazing what youth is capable of) that was passed on to him my Jason Collins. The thing approaches that curve you speak of very closely. He showed me some film taken by one of the Santa Cruz locals of J.C. alias Ratboy surfin’ the board at the S.C. Harbor mouth. He didn’t some pretty amazing tube ride and an air reentries on it. The thing rips. DaGooch says he’s never gone faster. Says something about that old double ender neutral shape idea and how responsive it is in the water I guess. The more we look at what the Vikings did the more appreciation we have to have for the engineering skills. ((Jim can you tell me anything about panel bottom boards?)) Mahalo, Rich
I’ve seen that done - a perfect parabola! The true double ender egg. When I was a little kid playing at the beach, one day I noticed the beautiful elliptical shadow that my round skimboard cast, standing on end in the sand… I decided to trace its mysterious, clean shape for further study… my first template.

I’ve seen that done - a perfect parabola! The true double ender egg. The shape works great with a thruster set-up if you keep ‘em short (6’ or less). They work best when the trim and turn sweet spots coincide. Once you lengthen them, the trim spot moves up and you have to step back or ride stink-bug to turn them (by then you’re better off going with a hull or standard thruster outline). Real flat rocker, little v or concave v in front of the cluster. Blocky rails with a hard tuck from nose to tail. Real comfy in the pocket or tube. Quick, short lines…Too much curve in the outline for bigger stuff. The shape works great for kneeboards too. Newbs

I had a nice panel V board that I rode and won the East coast championships in 1983. I shaped it as a light V, then added bands starting at about mid point and winding up touching the stringer at the tail. All of the major V was out at the rail area, where it really needs to be for use in turning only. This was a 5’10", so the tail wound up with some volume, not as radical as the old V bottoms,but thicker than norm.>>> Mahalo, Rich
This shape (recent link on Swaylock’s home page) is a near double ender… http://www.barracudasurf.com/Stingray.htm
This shape (recent link on Swaylock’s home page) is a near double ender…>>> http://www.barracudasurf.com/Stingray.htm Its got a much narrower nose/tail than the ones I made…looks like the trim spot is pretty far up from the fin cluster. I’m guessing it rides “skatey” rather than “drivey”…if you know what I mean…Is it a twin fin?
Aloha Underground, Mitch (former Kailua resident)here. My 7’10" Sting from Ben just arrived at LAX…unfortunately Ben could send me a center fin so I gotta hustle to find someone to make one quick. When Ben and I last talked he semed to mentioned that he would include a template for the board but…and maybe my connection was bad…but I thought he said it would be 6 3/4". Question. In your opinion, isn’t that a bit small for a 7’10"? Its based on one I saw Ben riding a few summers back at San 'O and malibu('cept my ain’t as thick as his!). Full nose, swallow tail, etc. Appreciated the info you sent last time and really need some advice and/or additional ideas here. Hey, does anyone still surf “Zombies”? Mahalo, Mitch

Hey, does anyone still surf “Zombies”?>>> Mahalo,>>> Mitch Sorry I missed your post until now (it was kinda buried) 6 3/4" is plenty small for a single fin set up, and kinda on the big side for a thruster center fin. I dug out the template I got from Ben it’s 8". If your looking for single fin or 2X1 style this may work for you, got FAX? How wide is your board at the tail block and 12" from tail? You could have someone make one for you or match the template up to a fin bust out the scroll or hack saw and sanding disc attached to a power drill and grind away. Got FAX? Zombies hasn’t been good since last spring. However, I got an access to North Beach and it’s been good with new sand washed out over the reef in front of the stairs. Love those Kona Winds.

Love those Kona Winds. Laters UNDERGROUND Don’t mean to hi-jack your thread…but are you talking about the North Beach on Kaneohe MCB? Man I miss that place. I surfed there all the time during the 5 years I was stationed at Bellows. Thanks for the memories anyways…
