  • Isn't boyancy volume divided by mass. My board should have the same volume and weigh the same if not more than the Yater.

    is a ten pound bowling ball as bouyant as a ten pound bowling ball with a hollow core?  How are you going to get the same weight if not more and keep it hollow, are you putting weights in it or 60 oz. of fibreglass cloth.  Most of my older boards are 30-45lbs..  And dont get all technical with me regarding buoyancy formula's I know surfing not physics.  I remember in HI when I did the Queens noseriding contest one of the Surftech sponsored guys glassed bricks on his tail to try and get it to hold the nose better.

  • i think if it comes out the same weight you should be fine.  seems like you're just taking weight from the core and putting in the skin.  but once you're up and riding, it's a lot less about buoyancy and more about planing lift which should be fine if you keep close to the yater as it appears you will.  what vacuum bag system are you using?

    Here is my set up.



    The compressor is from an old fridge. The bag is made from heavy vinyl from my local hardware store. Vac switch and vinyl cement is from joewoodworker.com

    I may have to go with Monetsurfboards suggestion and use san bags for this one.

  • Justin,
    cant the bouyancy issue be fixed by making the board thinner or in some cases narrower so that the amount of float would be comparable to a larger poly board?

  • wow - interesting.  nice job putting that together.  at one time i was looking at commercially available systems and they were very pricey.  i'll be excited to see your project progress!

    Are we going to ride in a yellow bus?  I prefer the long ones, the other kids made fun of me when I rode the short ones.

  • What I believe Onefin is saying, and I agree with is that iit might be too buoyant for its wieght.
    But, what I see as the solution to that is to be able to lay heavier glass on it.  Hey stronger is always better right?
    Surftechs are more buoyant only in that they take up the same amount of space as the fiberglass counterparts but wiegh a lot less.
    Thus the are "more" buoyant.
    Also why I agree that Surftecks are crappy nose riders, now if Mr. French made a surftek noserider that was extra thick thermal skin making it strongr and heavier, then it might be worth it.
    (The orange board r.i.p was just that, super thick skin)

    Try hard as it might be to keep the wieght of the board similar to the Yater.

    And yes we all want to see the "Shop of magic"
    And what size yellow bus?

    That size now put on your hockey helmet and sit down..

  • Buoyancy is a good thing to much isn't.  Surftech's are notoriously crappy noseriders because they are to bouyant and therefore ride above the wave as opposed to in the wave.  One of the critical aspects of noseriding is the commitment of the rail in the face.  As the water goes over the tail through following the rail line, the tail or back third gets sucked into the wave.  The water of the tail is what allows you to nail those tens, fives, or just to be on the front third of the board.  Is it absolutely necassary, no, I can noseride my 5'5" fish, but it helps in achieving lengthy tip time.  The best noseriders ever produced, Con Ugly, Nuuhiwa Bing, or Takayama Bing were all heavy and the reason being was to create that fine balance that allows long trips to the tip.  I find most high performance LB's dont allow for tip time becuase of the lack of weight and inability to just glide without slipping ass out.  I also think that a hollow board will give you tail slide and not allow the fin to engage when on the tip because the board has so much float.  There are other reasons but I will get back to you on those.

    Good stuff...and your right on, I agree.  To much boyancy in the tail will lend to early release.  Like you said, the water flowing over the tail actually puts weight on the tail, if its to little then your weight on the nose will cause a seesaw effect.  To tell you the truth...I'm still experimenting with what kind of boyancy the hollow woods have.  But remember, you have a solid wood stringer, ribs, deck planks, and built up rails (in my case all cedar)...so a cedar replica of a foam board will naturaly be a lot heavier.  But the problem is, its equally as heavy throughout the board...meaning the nose is going to increase in weight just like the tail.  Not good.  I had a couple ideas in my head about making a noserider...thining out the tail...making a custom mahogany (sp) fin box.  Adding a little weight and taking away a little boyancy.  But like I said, its all a guess game at this point.  Experimental...

    Thanks for the input - some good theories out there.

    and a good longboard is a board that has a ton of swing weight allow you the to swing it rail to rail with little or no effort cuz the board is so heavy it will do it naturally.  Also the swing weight of running it from tail to tip and how the transfer of weight in a board uis key.  Sure the Nose Devil and my Malibu Foil is awsome but i cant come close to my Con CC Rider or Con Ugly its a whole different ballgame

    is a ten pound bowling ball as bouyant as a ten pound bowling ball with a hollow core?

    but the answer is yes.  if they're the same volume.

  • You are correct, I am going to need extra support because the deck is going to be so thin.
