Does anyone know how fast a 49er needs to be travelling before it is planing (in flat water)? How much wind do you need to obtain this speed a) upwind and b) downwind.

Don't worry guys, at our clubs we have a crew of 49er olymipc hopefulls i.e. richard bone and chris rodway so we can jus learn it all from them. It won't be for a while though, at least 3-4 years. Will have to start saving!

The 49er is meant to be able to plain upwind in about 12 knoots of wind. We usually find that we don't think about what speed we should be going to enable plaining, we judge it more on the feel of the boat. There is a bit of a grey area where the boat is between plaining and displacement mode, we just go with what feels fastest but 12 knots of wind seems a good estimate.

Cheers 49er.  I was hoping to do some calcs on the planing performance, hence the curiosity about boat speed. 

Sorry for hijacking your thread guys!

They do not know what the optimum wieght is for a 49er because the weight equalisation rule has been lifted so now they are aloud max rakes and no lead. You really need to be about 142kg to sail it otherwise it just gets to hard to soon. At the Olympics Draper n Hiscocks were 146kg when the rule was in place, and the guys how won it were 163kg. At the moment people are thinking its about 155kg but there are plenty of teams out there going quick who are lighter, but i dont think theres any of the Performance or Olympic Deveolpment Squad Sailors who are heavier. Club sailors go up to alot heavier but the lighter guys will be faster unless its very windy and even then Draper and Hiscocks and people like that go unbelieveable quick.

49ers plane in less than 12 knots, you should be planning in 8 knots upwind and downwind. Just because your not flat lining doesnt mean your not planning, we plane in our 29er in 8 knots, its probably less than that even in a 49er. You have to bear in mind that downwind the 49er has an all up sail area of 59 square metres and boat weighs about 100kg all up plus the crew 250kg. It also has very little rocker to make it plane quicker.

Not sure on a 29er but the kite on the 49er is huge as its mast head and is cut fuller as well to enable you to go deeper and faster.......just doesnt hold up to reaches in a blow to well as you will just get forced down or flattened!! Think the main is around 14sq m and the jib around 6 leaving the kits at 32ish sq m

Yup it is that much. The Swift caries 38.8 total off the wind. The key is the bendy rig that depowers in the gusts. Remember that the harder the wind blows, the deeper you go.
Live large, love life, and sail fast.
