Building the 6'6" Gang Buster. Roy Stuarts Parallel Profile construction method.

I agree about the fat rails and thicker overall physique but I had in mind my slow head high mellow local beach brake type surf not hard barreling ledge type surf. I will not be entering compitions with it that's for sure. I agree it won't slash as hard as a foam thruster but I'm willing to bet it could be faster in making sections.

 

And it's not overly flexible the concave lamination has stiffened it up quite a bit.

 

Thanks guys. In all honesty I'm a terrible short boarder, I've been on long boards my entire life. The gang buster is my attempt to get nice at board building and to give myself a shorter board. I have some local buddies lined up to test it and give me critical feedback. Despite its weight it's still very very buoyant, I got it in my pool and all 200 lbs of myself couldn't hold it under , it would pop me right out. I will certainly keep you all posted on its performance and get some video footage too. I'm confident it will go nicely tho.

 

We've all seen guys on the Solid pancake thin alias with literally no volume and those things seem to take up plenty of wave energy. The gang buster like I said has a ton of buoyancy so it's weight wont make it sink. The weight should create allot of momentum and thus capture the wave energy quite well. This all my theory tho and I hope to prove it with a detailed ride report.

 

Well considering the lift created at the nose of the surfboard which will keep the annular wing at an angle that will create upward lift at the tail not downward lift the tunnel should actually push the tail out of the water better like a hydrofoil. My board has a flattish tail to rocker so the nose lift will be able to direct the tunnel angle nicely. Also the tunnel is known to have a very nice loose feel but still have sufficient hold for fast angles of attack. Rail to rail roll resistance is minimal. I've never used one so I had to try it out. I guess the only way to know for sure is to make one and try it out.

 

Well this tunnel in the board now is foiled outside only, I had made another that was foiled both sides but ended up scrapping it because I messed it up. I figured outside only would work well seeing how an airplane wing which is flat on bottom is able to fly upside down so I went with keeping the inside flat to save some man hours. Considering that airplanes with flat bottom wings can fly upside down tells me that upward lift is still achievable with the foil configuration on my tunnel fin. I'll agree that it may not be as efficient as an annular wing foiled both sides but I'm not flying at 50'000 feet I'm only trying to stay in a wave.
I like your idea about the tunnel holding the board into the water better tho that could be an interesting effect. Like I said I just had to try it out and hey if it sucks I can always cut it off and put a 2+1 set up on or something ... I left allot of tail blocking for this exact reason.

 

Well fellas its been a good time on here with you and all of the antics.. The Gang Buster is complete and now you can all place bets as to how well it will perform obviously.

 

Well boys I tried to test today but the surf was so terrible I decided to not curse myself by trudging through the hoards of miserable tourists at my local spot. This weekend in Maine looks very promising for a test run.
