Read my post....I'm not slating the board.....just nothin new that's all.......and I told you why I prefer pointed noses.......actually , for years when I was a grom (pre-legrope days), most of my boards had no nose after a month or so......I also remember a G&S square tail that snapped off right across the back of the fin base........and it kicked arse !!!!.. ......in any case , I can't see any great leaps here , but if you dig it who cares...........usedtobe69 wrote:kayu wrote:......there's no such thing as a major step forward in surfboard design...if you prefer a blunt nose , all that is , is your preference , and nothing more .....personally , I prefer a narrow nose , because it reduces weight at one end of the board , similar to most tails......it's also far better for the steeper take-offs on bigger waves , and gives better reaction to the mid rail , running down through the tail............did you ride a skid-lid in a former life?RossGW wrote:thanks for the reply's guy's these were the kind of reply's I'd hope to get. if we don't need the nose (or pointy end) why do we still have it? I know this is a fashion but surely a lot more people would have cottoned on to what George Greenough has been saying for a few decades now that basically we don't need a point its dangerous and has little function, (unless you are Julian Wilson, watch him tap that last six inches of nose on the wave on almost every air reverse he does).
And yes the Tomo is a major step forward in surfboard design is it here to stay? will it be the next board in a pro surfers quiver? or just a "that was fun now i want to ride my 6'2 x 18 1/2 x 2 1/4 again"?
Maybe you should ride one tomos wakeboards before slating them, might open your eyes a little bit to what's going on with them.
They're a huge leap from conventional shortboards, I've ridden both, have you ?
I don't like the guy, at all, but the designs are legit.
.....and there's no good reason against them.......they are definately better aerodynamically , and are far less effected by strong offshores.Roy Stuart wrote:Pointed noses are poor aerodynamically. This makes a difference especially in strong offshores. There's no good reason for them.

I don't see any relavance here.......no disrespect to George , but he should have stuck a ping pong bat out the window as well to see what happens...........or is he saying a bulb-shaped 3" thick nose is the go ?..........Philchapman wrote:In the latest issue of The Surfers Journal (21.6) there is an article by George Greenough about board building/dynamics. He comes to the same conclusion, and draws the analogy of putting your hand out of a car window at speed. Hold your hand flat with fingers forward (like a "pointy nose") and move it up and down, and feel the resistance it has to the wind. Then make a fist (like a rounded off nose) and do the same thing. The latter will be less influenced by the wind, and is therefore more efficient aerodynamically. Whether this can be felt on a board surfed by an average surfer in average conditions might be debatable, but I'd imagine there would be some difference felt at the top end of the range speed wise, and especially in strong off-shores. Greenough certainly felt the need to apply a rounded nose to one of his high speed windsurfers, and he could make it any shape he pleased. It makes sense to me that you would need to round off the nose as it blends into the deck and bottom also, to keep even pressure on both sides. That's the idea as I understand it.
That's an interesting link Phil ,but any aerodynamic effects would be dominated by the hydrodynamics of the board by a fair margin...........and ,I think , the ping pong bat would attract maybe twice the resistance of the flat hand simlpy because of the area being roughly twice that of the hand........a pointed nose in a strong offshore moves the effect of the wind further back along the board , because of the upward curve of the boards profile.......light-weight , wide nosed long boards suffer badly in a stiff offshore wind , where as a gun of the same length handles wind far better.......Philchapman wrote:I think the Ping Pong bat would have had similiar "handling" charactersitics as a flat hand, being roughly similiar shapes and thicknesses.
So, following up on your comment about poor aerodynamic profile of a pointy nose may I humbly ask for your reasoning in layman's term, please? And does "non-pointy" (rounded like an egg?) nose enhance the board's aerodynamic profile or does it only minimise the problem?
I am not being sarcastic, just genuinely interested in board shapes...I have another question once Roy (or anyone else?) answers my question above.
