So a bit of a Homer Simpson question. What are the best techniques for sailing in waves when on the beat, reaching out to the wing mark and running down to the leeward? Obviously a lot depends upon the type of boat you sail but I am only after some basics (which are usually too easily forgotten about) and I'm not worried about the quickest route eg high, low or by the lee but really just dealing with the wavey stuff. Too many times when sailing upwind I find my little boat resembling a nodding dog! Thanks Dics (my nodding dog is really a 300). |

it much the same for all boats, you need to have the balance and trim right all the time. to do this feel which way the boat wants you to move and move with it. the same with the steering. you movements need to match the size and timing of each wave. if you do it wrong the boat will tell you by slamming a wave. if you sit to far back the bow will lift to high and slap the next wave, if to far forward you will feel the bow catching on the wave, in just the right spot the boat will keep perfect trim as it goes over the waves with a bit of leaning for and aft as you go over the top of the wave the boat tends to trip over so you will need maximum hiking at this moment and you will get a slight rest in the trough. steering as you go up the wave head up and bear away down the back. you can use your body to help this by twisting your shoulders in the direcection you want to go. its best to let it the boat steer itself and just correct to keep on the proper course, for coppy conditions use more agressive exagerated sterring and movements, in swell longer and smoother

Thanks for the advice. I usually head up as I go up the front of the wave and then bear off as I go down the back. This can be down quite effectively by just sheeting in and using the hull profile to steer the boat. Also I try to time it so to keep as much of the length of the hull that is in the water as possible. This is to keep the water length at is maximum for speed as well as helping not to smash into the next wave. This is just what I have found intuitive and wondered if it was correct. Thanks again. |

i also sail a 300 and at the nationals found it so difficult to get into sync with the waves going upwind. i was wondering if i should have been footing off more in order to get into that 'power' zone?

Im not sure about other boats or if this really is the best thing to do, but we had pace with some of the fastest boats upwind at the 29er nats. As soon as we saw bigger chop approaching we would crack off a couple of degrees and have the boat going as fast as possible when we hit the chop, winding the height back on afterwards

only problem is that im too light to be able to crack off into that power zone and still keep the boat flat in anything above about 10mph....

the faster you go the less gusts blow you sideways though, if I were light id be making the most of every lull to bear off and gain as much speed as possible

i know what you mean as i do that in the 29er all the time. it just doesnt work the same when your about 3stone underweight

Sailing in waves?
Doh, where shall I start. A lot depends on what kind of waves. Lots of questions, are they tidal ( I don't mean tsunami tidal) I mean is there current involved, and are they wind with current or wind against tide. Then there's the wave speed, are they travelling faster or slower than you. Then there's the height thing, how much is the rise and fall. Then there's the how much wind in relation to the wave thing. All offer different techniques and opportunity for advantage to you, and disadvantage to your opponent if he or she doesn't spot any of what's going on. Far be it from me to get off on one here, especially in such esteemed company, and I'm also coming from a bit of a beginner angle here trying to make a boat do the same as what years of making a board do by instinct has proved successful. Lots of it is transferable especially the down wind in waves bit. You can use waves to overcome an unfavorable current, just dont get stuck in a trough. You can use faster waves than slower shorter waves when the currents favorable. Up wind, sometimes avoiding the waves pays, sometimes they can be a sign of a faster moving windward current, so go get in there and work them. If they're slamming footing off and powering through them is best. If there's not a lot of wind but the waves are big, the rolling effect under the wave surface (and look up jefferies sheltering theory) can help with some times sheeting out and in to balance, to legally propel you faster by sheeting out staying upright as the wave approaches then sheeting in on the recovery. There's simply too much to put in a single forum post, it's an entire chapter of a tactical sailing book, how to deal with waves, but one thing to definitely do, make them your friend, annoying buggers that they can be when they're icy cold and smack you in the face. they do make sailing more fun. |

It sounds like you are overpowered most of the time.
That's exactly why I sail a 4000 - most of the time we are overpowered. Unlike the contributor above we drive off in the gusts and head up in the lulls. To drive off in the gust you have to play the main-sheet. We don't cleat ours, and as we bear off we ease and hike hard then squeeze and relax a bit as we go up. We have enough mast bend, kicker and down-haul to enable this but never enough to feel underpowered. In a chop we modify this so that we hit the waves fast. In bigger waves we will squeeze up and then drive a bit on the way down. In very large waves we don't bother unless we encounter a breaking crest. Downwind in a fast boat like ours we tend to overtake a chop and so its a bit of a bucking bronco sort of ride which just means hanging on. In larger waves we are still too fast to surf them but we have to watch we don't lose heeling force and "tea bag" the crew because the pressure drops on the way up the back. However in my Laser and Scorpion days I really used to enjoy surfing and by getting in sync and really throwing your weight about you can get quite an advantage over the more sedentary sailor but it takes practice. In Lasers I certainly have surfed right up to the transom of Wayfarers by using their wake on otherwise flat water. The only surfing I get in the 4000 is upwind where a powerboat can provide waves to surf on since you are often on the brink of planing anyway. It sounds like you need to pay attention to your rig controls. Bend that mast (especially with down-haul) until you are only just overpowered. If the sail is flogging then you have to use more down-haul then you'll be able to drive hard in the gusts, squeeze in the lulls and in waves you'll have more options and control. Sorry I got carried away but I hope you found it useful. Edited by redback |
