All this "liter" crap is communism--keep it in pints, quarts, gallons, or move to Europe. Keep it "the American Way"!!!
If their talking volume and liters and crap then its more than likely a computer shaped board anyway using like aku shaper i think is freeware or some other shiite so it was cut on a machine and most of the guys that still shape by hand wouldnt know what a liter is and dont care but in fun they will use 12 oz beercans as their standard unit for volume measure to the kids that always ask about volume. And by the way them shapers is so glad when yu fuks leave with your whinning asses cryin about your board dont work.......
Like how many pints does it take to get really tore down on a really hot day , well a number of factors should be considered .... like the volume of the cooler yu have the beer in .
To get back on point: I had a hard time thinking of a all time worst board for myself... since if I don't like a board early on, I usually sell it quickly BUT I forgot that at one time I owned a K-step as well.. the shape was really appealing but surfed like garbage and didn't easily slip into waves... I actually held onto that board for a while thinking that it would only work in good waves. It was a waste! Board didn't work for me...
I don't think it's much difference in liter speak versus tweaking the width or thickness. My last board I told him I wanted to go 2 5/8...stayed at 20.5. Went to a 6' 2" from 6'. So, inherently I'm getting more volume (purposely)...we just don't go figuring it out I guess or harp on it...I agree finding your bearing point on volume is a good thing. I'm finding the aging process makes it a moving target lol.
The first custom board I had, I asked my shaper to make me a board that would make the wave at big Reef Road. It was like making a deal with a lepercan. It made the drop, made the bottom turn, and made it down the line. Damn thing would not turn. Couldn't do a proper off the lip, never mind a cutback.
First gen quad, tore a chunk of flesh out of my calf on that squirrely POS on a stomach high day, it was too out of control on the drop. That thing was a hazard.
Worst board ever was a 6' Hawaii Shape deep v twin fin, big wide glassed in skegs. It had a patch cut out of the deck, and reglassed, prolly from smuggling. My buddy sold it to me for $50. Would not turn. Always dug rail. The thing was a beast. No rocker at all. And a cork. For something so floaty, it was totally unwieldy, very weird.
I can’t think of anything I ever had that was a true dog. I err on the side of rider error. But, I’ve definitely had boards that I meshed with better than others I’ve had two customs both were exactly what I wanted. One I sold about a year later because I outgrew it a year later. But with that said, I buy a majority of my boards on Craigslist or other online market places. I find steals and will negotiate like it’s my job. If I don’t like it on the maiden voyage, I’ll sell it. I have made almost a hundred bucks on each sell with some times where I double my money. I have a Roberts Dreamcatcher in Varial foam/ hydroflex iii tech that I found online for brand new, legit brand new for less than half price. It is a $1000 custom order board, but there is no way in hell I’d ever spend that much money on a board. I’ll probably keep it forever as this is one of those boards that I feel really fits with me. It’s tough as nails and has sped me through many a choob. Premise of my story is online market places can be great thing if you have a keen eye for what you want and are willing to negotiate.
Yea... pretty much agree with all that. I usually don't use a cad program, but when I do it's aku. Sometimes I'll do a new template on aku just for the outline... play with it until I find what I like, then pull the dims off that to make either a masonite spin template, or just a bunch of dots right onto the foam. Then I'll just enter in the thickness and get a ballpark volume from that. If I already have some existing templates I'm using, I'll sort of design backwards and plug in the finished shape numbers into aku and get a ballpark volume that way. Or... I'll just cheat and look up a similar shape from a big name shaper that lists their volumes, match up the sizes of their board and my board, and get an estimated volume that way. The fish I just did this week was from an existing fish template I've used many times. Without even using aku I can ballpark it at about 30 liters... maybe 31. And that's about all I need to know.
LB: what is the density of the various foams? are they all within a few hundredths of each other? (using any unit) because to use volume seems dumb when the density value is different, it will create a different buoyancy youre former physics teacher right? help me understand why volume and not buoyancy is used, especially when different foams have different densities, or am I making that last part up? this has bothered me for some time as a firewire at 35L will have a different buoyancy than a PU at 35L
1) There are different densities in PU foam, and different densities in EPS foam as well. EPS is typically about 2lbs per cubic foot for standard foam, but you can get 1lb or 1.5lb, too. For PU foam, "blue density" is standard, but there are lighter and heavier densities, with each one about 5-7% lighter or heavier. PU standard foam has a slightly higher density than standard EPS foam. PU foam isn't uniformly dense... it's denser near the skins, and less dense in the middle of the blank, so it's not measured in lb/cubic foot. EPS has pretty much uniform density. 2) Yup... density matters in terms of how buoyant a board is, since buoyancy is a function of both volume and density. That's why I like to use the term, "float" instead of buoyancy. BUT... when you're sitting on your board, and to a lesser degree when your paddling, the board is submerged, so the buoyant force on both boards is the same - both boards are displacing their full volume, and if the volume is the same, the weight of the water they're displacing is also the same. But if the boards have different densities, one will "float you better" than the other. 3) Because as Barry said, surfers are morons. Everybody knows how a board floats them... some people know their board's volume... nobody knows it's buoyancy.
thanks, I see point 2, the volume of water displaced is uniform, independent of whats displacing it be neat to see a buoyancy/float Value, what would unit be?
