managing strong wind
14th January 2020 at 2:39pm #19291stevecParticipant
Advice needed! Every time I’ve sailed the OK I seem to have had strong wind – Brixham and Abersoch nationals and Grafham end of seasons ( I had to miss the last races on the Sunday), and last Sunday at Bough Beech when it was 22mph < 30mph. In all these I struggled upwind when the strong gusts hit as the base wind seemed to be already at the upper limit of the rig – I had the traveller down about 350mm so the boom end was just over the edge of the gunwale, the outhaul nearly out to the band, the inhaul neutral so the luff was parallel with the mast, the downhaul tight, and the boom just off the deck. For some gusts I could feather up but when the really strong ones hit I didn’t know what to do; if I eased the main the mast straightened and the sail became fuller, if I feathered up more the whole sail went aback and the boat stopped. Needless to say I was sitting out as far as I could so as much as possible of my 95Kg was being used. The mast is a Ceilidh with bend the same as Jim Hunt’s, as he advised me that would be good for me, and the sail was a HD recut from the original shape to the new mast bend by a reputable ex-Hyde sailmaker. I had the board slightly raised to try and match the average effort position. My previous experience has all been with stayed rigs so while I love the OK I’m mystified by some techniques which, when in my Solo would be rational, like easing the main when overpowered, seem counterproductive in the OK.

Steve, I’ve been having the same issue. I thought that raking the rig back in the big breeze would help but I found myself pinching even more and losing all boat speed. I put the rig back to nominal (similar to Nick’s settings) and pulled on more cunningham (pretty much block to block) and maxed out the outhaul. I eased the travel right out in the bigger puffs and tweaked it in a couple of inches in the more sustained lulls. Definitely went a bit quicker but still not fully dialed in.
I did play around with fully tensioning the kicker upwind as I’d do in all the other dinghies I’ve sailed and ease the main out a bit more but I chickened out after a while after nearly tacking without letting it go!
So I’d also appreciate any further advice going.16th January 2020 at 11:39am #19293robboParticipant
YEP. – I know this problem-my solution what with only being 62kg

Thanks both for admitting your struggles!
Paul what multiple do you have on your downhaul? I can’t get anywhere near block to block, but I did think this was one area I should look at after reading Nick’s latest guide. I have the basic 2-1 but I thought of adding an extra purchase in with a block on a strop off the boom passing through the downhaul eye on the sail and then the control line running through the strop block. I will try this on Sunday although the forecast suggests a light wind day(relief!)!
Robbo I admire your perseverance in the boat with that weight; you must be hard-pressed in a force 3! You must be like me and have an aversion to all the beach boats around.20th January 2020 at 10:21pm #19298Paul CraigParticipant
Steve, I’ve got a 4:1.
The HD sail I had on 2071 had blocks sewn on to allow for 4:1 and I always found it worked well. When I bought 2129 it came with the standard 2:1 which I always found a bit tough to setup. When I got the new mainsail I had a chat with Jim and he agreed and put blocks on it for me. I think you need the extra grunt with the Aardspars and bi-radial sails, but then I struggle to stay competitive above about 15kts so I’m clearly getting other elements wrong or my rig is too stiff.31st January 2020 at 12:17pm #19304johnbrookerParticipant
I sail a Solo mostly so take my advice as you will. I’ve found you can put the board up a lot without too much disadvantage. Use the cunningham/ outhaul as much as needed to keep the weather helm minimal. Once you’ve got the weather helm minimal you shouldn’t have too many problems.4th February 2020 at 3:11pm #19305childs87Participant
Based on Grafham (I was fast upwind, leading to the ww mark most races on day 1. but very good at swimming downwind) it was pretty hard to get set up perfectly, as it was very gusty and shifty, so I found it best to set up with a big groove to sail to.
The rig was on Nick C’s tuning guide like yours, but the difference from the sounds of things that I did, was I cranked on the outhaul hard and also had a lot of inhaul on too. I could have pulled the cunningham harder, but as it was puffy decided I would pinch more in the gusts rather than constantly moving sail controls.
I sailed finns a lot and we found that the outhaul was the main power source on the sail, so when overpowered this really needed to be cranked on hard! Pulling the inhaul tight pulls the draft and C of E forwards, so reducing helm and meaning you could stear without too much weather helm.
In the big gusts, I cracked the mainsheet an inch when they hit, but got it straight back on after the initial hit so that I could keep height.
Hope this helps…
