Hi guys,

I have recently picked up my new racebaord and have had the chance to take it for a few sails. I'm using a Severne Raceboard 9.5 and absolutely loving it. Now I just have to get my skills up so I can make it around a course without too much up-hauling!
I've been reading as much info as possible but just have a few questions (and I thought I'd give Bushfire a break from all the PMs!)

First up, so far I have been sailing in light conditions up to a maximum of 12knots, but usually about 7-10knots. What sort of rig settings should I be going with? I've mostly been using the recommended settings, but I'm thinking that in those conditions I might be over tightening everything.

Also, I think my boom may be too short! I am using a Severne ALU Race 220-250, (the sail recommends 247) and I don't seem to be able to trim the sail off the boom (at the recommended downhaul). That can't be right... (being 2m tall, I also have the boom height maxed out which probably doesn't help!)

I am struggling quite a bit with controlling the mast foot and centreboard, so have decided to 'set and forget' that until I've found my balance! Any general handling tips for a novice longboarder?

I will be doing my best to try and make it to the upcoming Oceanics. I won't be racing, but it would be good to chat with and observe experienced raceboarders in action.

Thanks for your help.

Tootall.

You can never be too tall!

Bushfire will respond regardless but in the meantime.....

The settings are the maximum (ie maxed out conditions) so your right, you don't need to be at those down haul and out haul settings in light winds. If your on Facebook, check out the Illawarra windsurfing page - tons of photos of severne raceboard sails, and you'll find most are bagging out over the boom - don't be worried about that, that's normal. Do you have a adjustable out haul set up? Very handy to experiment with

I'm 195cm tall and I have the boom probably about 3/4 high, so thinking maybe try it a bit lower and see if that gives some more control with the mast base / centre board issue. Others don't necessarily agree with me but I only use two settings with the mast track - all the way forward or all the way back. With the centreboard down I'd be keeping the mast track all the way forward. 'Trimming' the mast back backwards at all will change the balance with the centreboard and make the board more twitchy.

If your going to make the effort coming to the Oceanics, you should enter! You'd be more than welcome, and don't have to compete in every race if it doesn't suit - the experience however will turbo charge your learning!

Hey tootall,

Welcome to the world of all-weather windsurfing!

Re rig tension - in 7-10 basically as loose as you can. Although I believe the Severne has problems with the cams popping off if you go too loose - maybe one of the Severne owners can chime in here. Certainly with my Demon 9.5 in 7 knots both the outhaul and downhaul are literally slack.

You can probably get away with the boom, but I would think that boom is maybe *just* too short. Outhaul is the key on-the-water adjustment (if you don't have adjustable outhaul and downhaul, I'd highly recommend adding them) and being able to crank on some excessive outhaul can get you through a gust that would otherwise have you swimming. Plus I find setting the boom at about 2cm past the recommendation helps the outhaul run more freely.

Another factor is that if you have a softer than recommended mast, you'll get more bend and therefore need a longer boom.

*If* you are getting another boom and have the budget, the Severne carbon boom is quite nice and reasonably priced (relative to the astronomical prices of the other manufacturers that is). If you can stand the sticker shock, a carbon boom is one of the best upgrades you can make, and they last for donkey's years.

As for mast foot and centerboard, I'd recommend you at least go with two different settings - mast track forward and centerboard down for upwind, mast track at least slightly back and centerboard up for downwind. Certainly at 12 knots and beyond you'll be struggling otherwise. Make sure both are well lubricated (I use Inox grease from BCF) and in a pinch, don't be too proud to drop the sail and wrangle the track and board by hand. Obviously that doesn't work too well for racing, but while you're learning you'll at least be sailing in the right trim.

Finally - if you don't have an EZ-uphaul (the doodad that lets you use your harness to uphaul), get one immediately!

While we are at it any tips for gybing a longboard? Been sailing in the Sydney Harbour, however often the swell comes through the heads mostly perpendicular direction to the wind. Tacking is all good but when I know a gybe is coming up I also know a swim is coming up. Talking of mainly non planing gybes in around 10 knots of wind. Can gybe formula board and slalom board ok, but my Exocet Elite is proving a struggle for me.

Hey Dean,

Light wind longboard gybes can be tricky and the Exocet is a bastard given it's very narrow but thick tail. Anyway....

Centreboard up - not impossible to gybe with it down but makes it much much harder

Weight back - ideally your trying to pivot the board around the tail, sounds obvious but if the board is flat it won't want to turn

Be aggressive with your feet pressure - particuarly the outside rail, trying to push the rail around, pulling in on the inside foot doesn't hurt either

Try and draw the rig over the board and to 'leeward' - basically trying to get the balance of the sail over or past the outside rail

Don't be in a rush to flip the rig, you really want the board to flatten back out and your feet set and planted before flipping, even try sailing out on a broad reach clew first while practising, then flip

Then do it all in not a lot of wind and in swell - easy!

The other tip for gybing in moderate wind is that sometimes a longboard will carve into a gybe, then at a certain point fall off the plane. At that point the foot steering actually reverses, i.e. the board will turn away from the direction of lean instead of towards it as in a carve gybe. Even more so if the centerboard is down even a little.

For example, if you are carving to starboard into the gybe, you'd lower the starboard rail. As soon as the speed drops to a certain point though, you actually lower the port rail slightly to continue the turn to starboard. That switch in foot steering can throw you straight off if you're leaning into the gybe and the board suddenly starts turning back to port.

Yep that's been happening as well. I was originally thinking that you only sunk the outside rail when the centreboard was down. Thanks

Thanks a lot for your help guys.

I'm glad my thinking was right in regards to the downhaul/outhaul settings. Next time I sail in similar conditions I will try the downhaul 10cm (?) from max, and see what happens. I have set up an adjustable outhaul, so i'll play with that more often.

I still suspect my boom is a bit too short, but will have to make do for another month or 2. If/when I do get a new boom, with a sail recommending 247cm, what size boom should I be going for? The 210-260 or the 240-290? Is flex an issue when getting close to the max on carbon booms?

Thanks for the tip with the centreboard/mast foot position. If I can get used to using forward/down and back/up, then I'm sure that will help in the long run. I did notice that my gybing turning circle was quite large with the centreboard down.

Thankfully I already have an EZ-uphaul - my back would be feeling it if I didn't - I lost count of the times I used it!

I also got thinking about insurance last night. At the local club it's compulsory to have insurance (to race at least), and I was wondering where you guys go for board insurance? I haven't really had a look around yet, so maybe it's simple/obvious, but just thought I'd ask.

Cheers.

Hello again fellow Raceboarders,

I've had 4 more sessions on the board now and are starting to get the hang of it (all sessions in 8-12ish kts). I have a few more questions for the brains trust...

First, I am getting more comfortable with the mast foot/centreboard manipulation, but I still struggle getting the mast foot forward when heading upwind again. Should I be moving the mast foot forward before rounding the mark or after? I've tried both, but neither has proved more successful. Also, I have found that when not fully railed, it seems better to have the mast a little back from the front to balance the sail with the centreboard, is this right? Or am I doing it wrong?!

When it comes to rigging my sail, the top three battens have creases that run from the leach end of the above batten, to the luff end of the batten below. What does this mean? Do I need to adjust batten tension, and if so, which way?

Lastly, what effect does the tack strap have on the sail? Should I be doing this up tight, or just pulling the slack out of it?

Thanks for your help.

Tootall.
