    Gull Wing BLEF Trial #1

    Date: Thursday 11/28/14 and Friday 11/29/14

    Location: Ocean Reef Park, Singer Island, south of the south rock, behind the hotels.

    Conditions: Weak knee to waist high bumpy wind swell, with an occasional chest high peak. Semi lined up. NW wind 15 mph with gusts. Drifty to the south. Incoming high tide both mornings making it inconsistent. Water 74 degrees, air 60 degrees. Two to four people out.

    Results: The fin worked really well., It went fast on gutless waves, turned real easy too, although no opportunity to see how it carves, noserides, and cutbacks. Lots of initial lift on the takeoff, and it did not bog at all on the bottom turn, it actually sped up due the the lift it creates. Roy mentioned this factor earlier in the post, but I don't remember the whys and the hows. I'm going to keep it for another bit to see how it works in better stuff, then send it on. But so far in the conditions I mentioned, it worked better than the True Ames 8" Squirrel Cutaway, and a Standard 9" longboard fin. Kudos Roy!!!

    sounds good. what is the comparison you can make to your usual fin? Is your usual fin the ones you've mentioned here? Also how do you get on the trial list?

    Cheers Surfdog, that's a nice in depth report.

    This is a nice turn.

    :cool:

    water 74?

    That's nice too!

    My usual fin is the True Ames 8" Squirrel Cutaway. That is the one mentioned here. So far, the Gull Wing BLEF works better, in weak conditions. I will try it out in better conditions, then it will be sent to CelmsonSurf (He asked first). If you want to be a tester outer, contact him via PM.

    Gull Wing BLEF fin trial #2

    Date: 12/28/14

    Location: Hobe Sound Wildlife Refuge, north of the parking lot.

    Conditions: 3.3 ft @ 16 seconds east groundswell. Light south east wind 2-5 mph. Air temp 80 degrees, water temp 74 degrees. No one out at first, then a handful of people spread way out. Lots of surf fishermen. Spooky water. Almost glassy waves, long period swell breaking fast, almost closing out, but lots of long waves to be had in the chest to shoulder high range. The takeoffs were steep for a longboard, and later as the tide filled in I switched to my fish as it got steeper and hollow.

    Results: the BLEF Gull Wing worked really well in good surf. It did not slide out on bottom turns, but held nice in steep sections and the fin helped the board accelerate and make sections. It was too sharky to ride without a leash, so there was some drag but the board still hauled ass. I would recommend it.

    Nice job Roy! Even though you can be pompous and sensitive like a diva, you have created a very nice fin. Cheers and Happy New Year, you sheep banger. I'll send Clemsonsurf the fin in a few, but one of my buddies wants to try it out first. He is an expert longboarder and wants to take it out in big waves (DOH plus). So stay tuned for one more report.

    I prefer the 8" wingnut cutaway i've tried both and its a tad more loose than the true ames sq. cutaway. Either way the cutaway makes the board ride the way I like. As for the Roy, it was nice of you to try it but the hell with buyin it.

    Yesterday I ate a sh!tload of tacos and this morning I ripped a huge BLEF (Big, Loud, Enormus, Fart) at my desk.

    This makes me want to build a hydrodynamics pool and put this thing to a test. I better not see any bubbles. otherwise it kinda needs a breaching dolphin on the bend right there. Otherwise still - we'd have bread cutters on planes and subs a long a$$ time ago. Idk, I only got a mech eng associates...

    I can get you a fin box which measures lift and drag for $20k... cheaper than a test tank.

    For actual surfing tets all you'll need is a fin, if you have a board with a single fin box.


    I nice presentation of a couple of allusions to informal fallacies of argument.

    Nah, I think for 20k I'd rather have a tank, where the hydrodanic flow characteristics of the "device" can be visually evaluated as well as relying on stress and pull reading by a god-knows-how-accurate signal receptor.
    What are the advantages, to your mind, of the ribbed edge which cannot/has not been achieved through experimenting with the geometry of the fin, as well as the material?

    How would your box measure the play In the rake due to water load, which is fairly critical to the slip to drive ratio?
    With a shape like this wouldn't your reading be way off at the base, unless you know 100% what polymer you cut the fin from, and have a math degree. If you do, let me know, I'd be curious to run a few tensile strength test myself.

    Besides, allusions concerned, i have no problem admitting my own short comings, I work on them every day. And I improve. But then again, we only live for so long.

    You may provide a chart for those advantages compared to a regular fin, I assure you I can read one.

    How would your box measure .....

    That is a question to ponder.... Roy if you had a mangina or if you already do how does it measure? Can you fit a Blef inside it? How much would it cost to have you try? There is a price on everything in the world of Roy, correct?
