Iconoclasts !

Slowboarders ! :wink:

Hehehe

Tom Bloke Please post evidence of your boards going at top rate filmed by a neutral party.

Couldn’t resist posting the video that you have requested of Tom

http://www.youtube.com/watch?v=TUtD19jSN8Y&NR

Please define ‘neutral party’

Oh, and by the way, video footage isn’t ‘evidence’ of any claimed speed, so no can do.

GPS is far more accurate than eyeballed video estimates, and that’s that.

Also I have to say that producing evidence which would stand up in a court of law is a daunting task . . . . and I’m not on trial, I AM MERELY REPORTING my findings.

:slight_smile:

Hi ojshjs, whats the GPS that you are using in the video please? Im using a Navman M300 that I strap to my ‘offside’ forearm. Thanks, spuuut.

I would be a neutral party, I have no vested interest in wether or not you are proven, and if you have some sort of land mark in the video such as bouys placed every 25 meters to observe your speed(which after all is a relative term) people would easily be able to judge your true rate of speed. If your equipment can preform as you claim, which I would be happy if it does because it would open up new surf spots, I am sure you would have no objetions to prove your claims by a scientific means.

Well you are right about the boards opening up new breaks, they have already done that at my local . … . but don’t tell me that you are seriously considering coming all the way over to NZ to anchor buoys all over the break ? . . it wouldn’t work the break is so shifting that you would have to use hundreds of them. … and then there is the problem of camera angles. . . . . far better to use GPS. . . which of course we are already doing. . … . as for ‘scientific’ means, just say hello to GPS technology !

What I don’t understand is what purpose a ‘neutral party’ would serve. . . . you going to check what the gps says after the surf ? . . . seems a lot easier to let us do that little task don’t you think ?

Here we go again. Moderators, PLEASE put a lock on this thread!!!

THe waterproof speedo is a garmin geko with an aquapak on the outside to strap onto upper bicep

I will post a better video of the 31 mph ride in a few days.

Roy makes me laugh the videos are so classic

he posted some bs response on the vid clip about going 37 mph LOL

hed be lucky to hit 1/3 to 1/2 that speed

Hey James,

We have regularly done 35 mph and the 37 mph speed was recorded on a Garmin Gecko, same as you are using . . . . I’m stoked that you did 31 mph but you have a way to catch up, I’m confident that we will be getting readings over 40 mph on the new Squidtail.

Realise that we are talking about a peak speed, not an average speed. . . . on a ride lasting nearly a minute we are reporting the fastest second, most of the ride is likely to be much slower, particularly if there are slow sections. . . . it’s not as if the entire ride is 37 mph, do you undestand what I am saying ?

I am surprised that you blithely write off my readings, (which have been done diligently and reported honestly) while expecting us to accept yours . . . a little childish don’t you think?

In my opinion we should be supporting each other in this new sporting enterprise, and I must point out that I have, over the last few years, always accepted second hand reports of your speed readings without question

Also I notice that your video says " Speedometer concept by James Sowell " . … . . . what’s the story with that. . . you know that Garmin thought of it first and windsurfers have been using them for longer than any of us !

I think that your video is fun, and accept your readings, do the same for us please.

Regards,

Roy

Doug, I think that those who are interested should be allowed to discuss surfing speed here provided that the conversation is polite, after all, it’s only one thread !

In my opinion there’s no need to lock every thread where there’s a little bit of disagreement as long as the discussion is civil, if you don’t like it you don’t have to visit the thread.

Regards,

Roy

Passionate, lively debate is fun and enlightening, aside from being entertaining.

As long as things don’t get personal…

Roy, the purpose of the neutral party is to keep you honest. In competitive fishing, they have a person who has never before met the competitor ride and fish with them because they don’t want any “fish tales”. I am simply suggesting that you have some one whom you have never met before observe and confirm your findings. And I would be GLAD to go to NZ to be an observer.

Hi James, thanks for the info, I dont know if those products are available in Aust but I will look for them.

James, Ive been doing testing on bodyboards too, do you have any tips for getting a higher reading on a wave of a set height? So if you had a wave pool to test in, what are your thoughts on how to achieve the highest reading? Sans engine.

More rigidity in the board, less drag( knees and fins), different rail shape, channels,…whats your theory? Or what would you guess?

Thanks, spuuut.

Correction:

The neutral party is there to observe for himself what is going on, NOT to ‘keep me honest’ I am honest already thanks !

If you are really keen to come over to NZ and hang out with us at the beach then that’s wonderful, I’m sure we will have a good time, make sure you get a 6 month visa though, the swell is somewhat inconsistent due to El Nino.

Cheers,

Roy

what wwould be the best months to visit. Though it may be a year or two until I am able to go I will take you up on your offer.

Hi Roy

looking at the vainui footage on that little right hand peak

it seems to me that when you get the board round off the bottom and put it into a trim

you seem to be going pretty quick

as fast as anyone/possbly faster, ive seen surfing a wave of that size

on a long or shortboard

so im not doubting your boards are fast in trim

i do have to question the accuracy of gps readings to measure speed on a wave though

it doesnt measure the speed of the drop for a start.

so if surfing a twenty foot wave and your going down on a pretty steep angle at pretty much top speed, your reading would would be quite slow i imagine.

as the gps only shows the distance youve traveled over land

a propellor log device would record the speed over water far more accurately.

if you get reading of 60 k/ph

im bad at maths mind you

but that would be about 75 meters in 3 3/4 seconds

thats seems impossibly fast for a surfboard

looking at the length of you board and the counting the seconds over distance travled

im dubious about the gps reading

i think you should consider a log device

and then all arguments would be moot
