Hello All,

Went sailing at the weekend, i was using a fanati shark 160 and a 6.4 sail. I think the wind was around 15ks but i still couldnt get the thing to plane and when i did the nose just wanted to turn up wind, im thinking that need a bigger sail? can anyone recommend a easy to rig sail around 7.5mtrs

cheers

How strong was the wind?

If you were in Sydney on Saturday then the wind was plenty strong enough to plane with a 6.4.

I think maybe either i hadnt set the sail up very well or the sail was not big enough to pull the board up its 165 ltr and im only 67ks.

When you get planing the board sill steer more like a surboard so if you have too much weight on the windward rail it could be making you head upwind. Are you fully sheeted in cos if not it will only power up the back half of the sail.

Your sail size is fine, I'm 68kg (getting fatter as I get older and 39 now so starting to go down hill fast but thats another story) and I have a 6.6m but go down to 5.8 when its 15 to 20 knots. It may help to check out your sail manufacturer's rigging guide on the internet as not enough downhaul can make it difficult to handle.

Get someone to check you out, you should be planing in a true 15 kts, unless you over-estimated the wind, in 11-12 kts you might need a 7.5.

I'm 67kgs and can plane on a 90l board with a 5.5m in 15kn.

I'm thinking a 160l board may be too big, it can be hard for us light weights to "unstick" a big board.

Nose turning upwind could be because you're not getting your weight back far enough. You could try moving the mast foot further back, that way the sail doesn't rake back as far, and you can get back further.

I'd suggest checking the board trim out while you're getting going - if you're on the verge of planing, you're probably pushing a small hump of water in front, and if you don't have the board flat crosswise, it'll tend to slide off one side of that hump or the other. It may be that you've got your weight a little more on the windward rail, and that's causing the board to slide off the upwind side.

Also worth looking at your boom height - if it feels like you should be planing, but you're stuck to the water, try raising the boom to around neck or eye high when you're standing by the mast. That'll help get the weight off your feet, and get the board to un-stick better. It'll also transfer a decent chunk of force to the mast foot, which'll definitely help with the turning upwind thing.

Try consciously pushing down and forward through the boom - like you're trying to push the board along. That helps get over the 'hump' and to get planing.

What size fin do you have on there at the moment? A bigger fin might be an easier/cheaper option than a new bigger sail if the existing one is a bit small for the job.

All advice above....just to add...

I find that by positioning my back foot across the centre width-wise (even slightly past it) when trying to get on the plane in light wind (165lt board) helps immensly, pushing toes to flatten board. The flatter the board is crossways, the sooner you'll plane. If you're 'digging' the rail in, you'll just slog, or keep going upwind.

The board & rig combo you're using in that wind should easily do the job, I've planed in those conditions (6.5m sail, I'm apx. 110kgs). Perhaps look at 'tweaking' your rig, less downhaul & outhaul, I found that by trying to shape the sail like an aeroplane wing?!? when starting off in light wind did the job.

Yes and stearing more downwind just before you are trying to plane. Most people are trying to plain on a beem reach and as you sheet in you put pressure on the back foot and the board rounds up. If you are sailing on a broad reach 45 degrees off the wind and sheet in the pressure goes through the mast foot and front foot and you squeeze the board on the plane then gradually steer the board upwind as your weigth goes back and the backfoot goes in the strap.

Boom up higher is also a key.

I had problems planing when I first went out with my new rig. I can relate it is very frustrating.

I'm 63kg's 161lt board with 42cm fin, using a 5.7 sail.

The main problem I had was not sheeting in enough and not getting my weight off the board. These two sort of come as a package, the more you sheet in the more you have to lean off the rig, getting the weight off the board. Also make sure you are getting back as far on the board as possible.

The harness has sort of sealed the deal for me now, can keep the board up on the plane as long as the wind doesn't die off *shakes fist*.

Going out today (just waiting for the tide to come in) using the 6.0 to see if it gets me through the lulls better. Not going any higher until I am comfortable in the footstraps.

It may be your rigging or it may be your board size. Don't know how long you have been at it, but assuming you are just starting out, the common thing is to expect to just be pulled onto the plane. The more experienced guys go out with smaller sails and work the board and sail to get on the plane. I am really not the one to explain these techniques, but there are some good DVDs and plenty more experienced than me to help.

Seems like you've had some pretty sound advice so far. I used to have the exact same frustrations until I came across Guy Cribbs website, checkout his section under "Stance", for 'Early Planing' and the 'Missing Link'.
www.guycribb.com/windsurfing_technique_holiday_DVD_0076v01.htm

I also found that a using just enough downhaul to remove the tension in the leech and using just enough outhaul to let the battens slide halfway around the mast worked for my sail (North Natural 6.2) in marginal conditions.

Good luck with it!
