Hey guys.... have silly noob question. Ive just picked up 93ltr JP Freestlye Wave. Ive got 3 sails: 6m cam slalom, 5.6 cam slalom and a 5m wave. I weight 85kgs and wondering how many knts I need to get planing nicely. Havent sailed in 10yrs, but i dont want to pack the car and all just to get out and plod around. Whats the min wind i will need to have some decent fun. Cheers

You should get going in a steady 15 knots with the biggest sail. 20 knots no worries.

knts for planing

thats what i said the last time someone blasted past me when my sail was too small to get going

Awesome Reflex.... useful post. Thanks for the input

Been surfing for 30+ years and this is the deadest fiorum I've joined. Pretty lame. Time to just get out there, rip and forget about forums. Was hoping to meet some cool peeos here but the waters edge is a good bet for that. I can't help but think sailors are a bunch of rich snobs who would rip solid waves if they had the fitness and nuts. Laters ****s

Most probably people are spending time away from their computers, tablets and phones today. Usually this forum is pretty lively with caption comps and questions about ding repairs so give it a go.

Where are you planning to windsurf and what sort of windsurfing do you want to do?

Finally a decent post. My first pm to a member selling a board resulted in an abusive txt msg containing multiple expletives. .. made me wonder about the community. I'll just let my sailing do the talking from here. Cgeers.

I just read your other post about board selection. To be honest a 93 litre board might be a bit small if you want to maximise your time spent on the water. It will be a great board once the wind is over 20 knots but could be a bit small under this strength. You would also want to look at getting some bigger sails.

For example if I had my perfect quiver of sails and boards for my style of sailing which is flat water blasting type sailing I'd have the following:

An 8m cammed slalom sail
7m to 4.5m freeride RAF sails in half meter increments

I'd like three boards, around an 80 litre slalom board for going fast on flat water in strong winds, around the same volume fsw board for comfortable sailing on bumpy waters in stronger winds and around a 120L slalom/freeride board for winds below 20 knots with the bigger sails.

That's me though. Many people go for smaller boards and choose cammed sails for flat water. I find cammed sails are too much of a hassle and expense for the performance they offer.

I weight a little bit less than you.

If you want to get into wavesailing then its completely different.

My guess would be 18 knots to be powered up comfortably. You might want a sail closer to 6.5 or 7.0 I'd think.

I'm 68kg and ride my 78 FSW in 18 knts easily with a 5.9, so 85kg on a 93 FSW litre should do about the same.

If you read between the lines i was actually offering you some pretty good advice. You are in NSW. Your go to combo at 85 kegs should be a 7.5 and 10 - 110 litre board. Thats you bread and butter - and then work down from there.

On the 7.5 you can go cams or no cams - i strongly reccomend something like A Severne NCX 7.5 - super easy rigging - cams may actually put you off the sport... but are great when tuned.

your welcome!





Not too sure about cams on a FSW - looks like you have some pretty mismatched gear there...

Geeze pixel. Are you okay? Just read your description. That's a lot of hate for someone who just wants to have fun.

I've got a 91lt & only wave sails. use in waves & flatwater. 5.4 can get me planing in 13-17 knots. 18 knots is comfortable.
.
flatwater rig up a size in general. I'm about 83kg.

I thought it was very clever.
Maybe calm down a bit a figure out who's who before you start ranting.

The first reply was spot on.

Sorry... got a very abusive pm which the guy later apologised for, but guess it left a bad taste. I'll hang back for a while and see how things go. Btw, yes, I've got a bunch of mis-matched gear. Mostly second hand, but ypu gotta start somewhere. Peace yo

I'm 88kgs. Like refllex I use a 7.5 with a 110 lit board for 12 to 16 kts and change down to 6 when the wind is 17+. I've just bought a 103 Kode FSW which I intend to use with my 6 on 18+.

I endorse what Mark has posted. Kool down. this is a helpful friendly forum. You get out of it what you put into it. If you don't get a response straight away, be patient, potential respondents may be sailing, enjoying their family or friends company or just getting on with life. If someone has been ****ty with you, thats no excuse for you to be ****ty with others.

Good luck with your sailing. Keep us posted on your progress.

From my scientific point of view there are two VERY interesting question that I always want to investigate:

a) what is the minimum planing speed (in ktn) for the most efficient board

b) what is the min wind speed to be able to plane in ktn on the light wind gear

I will be very grateful for input on above questions

Hey PP, you won't find a more friendly sport.

In my time, people have helped me learn (free), lent gear, helped rigging, even sent free gear for free (From one of the gong crew).

Totally unlike surfing, which from my experience is full of wanna be Bra Boyz and ever swelling packs........ sure there are some decent surfing folk... but its over populated these days and will never be as friendly as it used to be.....

So who's plaining and in what knots?
<div>

someone asked - what planes first

this one came from James Douglass blog as well
not sure where he got it - or how he derived it - if he made it

legend: LB means longboard, F is Formula and B&J stands for bump n jump

for a Formula to plane that early requires technique - pumping, etc

for myself at 100 kilos, i plane passively at about 12 knots - no pumping - with a Free Formula of 93 cm and a 10 sq meter sail

for short boarding, my windsurf buddy prefers about 15 to 16 knots. that is when the beaches usually start to get more crowded :-)
especially on a beautiful sunny day !!!

It seems that kiters have made the biggest inroads into the lower planning threshold over the last few years. I used to be confident that on a formula board with an 11m sail I would be the last one planning - that went out the window last year/season. I have seen a 20m kite with a raceboard planning continuously in what I estimated to be 6-8 kts (I was out on a long board with my son just puttering). This seems to confirm the Olympics ideal that they can race kiteboards in ~6kts.

Perhaps the formula rules limit the planing threshold. I think I once read about the board selection for the Olympics. Starboard put forward a board designed to get planing in about 5 knots of wind. The board was wider than a formula board and the fin was longer than 70 cms.

Ha ha, you didn't read his profile then ??




Problem here is that everyone seems to be linking 'planing' with 'decent fun'

If you have a 93 ltr wave orientated board and a 5m wave sail, then you don't need to plane to have fun, you need the right spot, waves too ****ty to surf and just the lightest of breezes.

No idea what that graph thing is saying. It appears to be saying that what ever shape and size water craft you have it planes at the same speed and that there is a point at 14.7532 knots where every type of craft has exactly the same mobility. I don't think either of which are vaguely true.



If you want to know the speed at which an object planes we need Ian K.

I understood the maximum speed you can travel in a non-planning hull can be approximated as 1/root2 x hull length in feet = max speed in knots. More power or energy creates a bigger bow wave which needs more power to push, so you reach a maximum. But I would suspect that a planing hull can jump its bow wave and get on the plane below the maximum non-planning speed, hence it is nowhere as simple as saying the planing speed is equal to a vessels length.

Can you or Ian elaborate a little bit more "what is actually plane speed " for the most or our vessels ( different windsurfing boards, kite or even boats ?

Hull speed is expressed as 1.34 X the square root of LWL, or length of waterline
