Unhappy

nonpr
So I guess you are selling the battery operated suits then Nonpr ??

Ofcourse heat on Torso will help keep all body warm but GOOD suits do that without batteries.I have sailed through loads of Northern UK winters perfectly OK without hood;gloves or batteries.Excessive heat will just be lost through higher rate of heat loss.(Double heat gradient quadruple heat loss blah blah blah.)

PROBLEM IS NOT PRODUCING HEAT ITS KEEPING IT !!! Try batteries/element in a woolly jumper;see how warm your toes are then ???

Case of dont knock the products I`m selling them ????

My mistake Nonopr .
You arent selling them ; you are representing them.
"email me about the brands I represent"" ??
No thanks. Pirating somebody elses website ??? Nice one.
Then you have cheek to knock me ??
BTW if thats worst comment you`ve read you need to read more !!!
Perhaps its onset of Hypothermia ? Could even be Hypathermia with wrong batteries. ???

I might be the rep for RipCurl in Puerto Rico, Caribbean and Costa Rica, but none of those areas really need this product and telling you what we have is just help, if you dont want to hear it, then no problem. But I dont hijack anyones website to promote anything I sell.
By the way i think you forgot this is a FREE FORUM SECTION group and the forum groups are to have discussion about product, new things happening, trends, etc. etc etc. But on the Free Forums you can do what ever you want , less porn or other obscene stuff

I am equally passionate about the equipment I use and that happen to be Starboard, MauiSail and Vector fins and those guys dont send me any free product or I dont get any special discount and I still recommend them as the best product there is, In my opinon. Take it or leave it.

Red face

So bascally you never sail in cold water and haven`t used the mentioned suit.?
Your reccomendations are third party and made because you happen to be rep for products mentioned.Another nice one !

Yes its a free Forum.I`m not telling folk THEY ARE WRONG. You are. (Because you`ve read somewhere suits are good ???) Its a Free forum to expres opinions not push the gear you sell.

AND you have a direct link on all your posts to your "representation site " ? (Selling guess what Rip Curl)

Yes Rip Curl are decent suits. No better (perhaps no worse) than many others. The battery pack is (IMO obviuosly) a gimmick and a potentialy dangerous one at that.
Do the maths. I have. ( ie the heat available from batteries and the heat produced by the body; its blatantly obviuos then.You`d need a battery size of your board to keep you warm in water below 6 degrees or so.(Our sea temp !!)

Like they say BBS. Bullshit Baffles Brains.

Think I`ll leave it.

Take care. Good sailing in that warm water over there.

I totally agree with that.
If you're serious about windsurfing in cold weather, try a good drysuit and nothing else...

I was actually one of the test persons in the artic with that suit and you are wrong about the need of a big battery, we used two celphone size batteries and in low we got over 3 hours of service, in med it lasted 2 hours and in high lasted about an hour in -10 celcius. I used gloves and head cap and booties, there where a few of the guys that surf with out any other than the wetsuit itself and no problems.
BUt to make myself clear here:
I AM NOT TRYING TO SELL YOU A SUIT> it was for your information and contibuting in the forum.
I guess you dont need my opinion you already have one set. Why then ask for opinon in this forum?

Question The maths ???

A human body generates around 100 watts of energy per hour.(Obviuosly dpends on work rate but this is the baseline sedentary figure for a person consuming around 2500kC a day)
This could easily double during exercise. (ie sailing)
If your body is losing more than that produced eventually hypothermia will result.
(see http://answers.yahoo.com/question/in...5115020AAO4dNe)

A lithium phone battery operates at 3.6v and they are normally rated at around 500maH.
(ie it can supply 500mA for 1 hour or 250mA for 2. Or if called to do so 1 amp for half an hour.(or infinite for briefet of moments hence safety issue)
This means the batteries (mentioned) supplied 3.6v x 0.25A x 2 W of energy per hour.(volts x Amps = watts)=Approx 2 Watts per hour .(its actually less) This is a max figure. In reality batteries dont perform quite aswell as quoted (especially when cold!)

In effect we are trying to warm up a machine that generates at least 100W per hour with at most 2 W per hour !!!

Make your own mind up !!!

A car battery can supply upwards of 50Amperes hours. Try warming your car up with it. (Eectrical heaters for cars are available. They dont work either.

Heating is very expensive in electrical terms.

If you were warm in -10c it had almost nothing to do with the heating element.
(You were probably supplying more heat to batteries than them to you; I dont think they would perform well at all in water of -10c without something to heat them; ie you !)

Placebo effect ???

Apolgies.
Just looked up Lithium battery operating range.
Apparently they would operate quite well at - 10.
But they`d still only supply at best 2W per hour.(Wouldnt make a cup of cold tea !!!)

Batteries or not, as a winter windsurfer I've never needed any device to heat my suit. More technology means more risks of failure more things to maintain (I guess the batteries need charging) and added weight. Maybe in some kind of survival suit for extreme conditions where people just stay passive in the water, but when I put my 97 kgs. into activity, even in zero degrees, I just don't freeze in a proper winter suit.

;-)

Floyd, I just pointed you in one of the many directions to solve a cold water problem. IF you have a RipCurl store near your area, please visit the store and try the suit and then express all critizism you want. I am open for it. I am sure RipCurl will appreciate the comments too.
