stern in water So 35

[corksailor]

No matter how much I move the crew or weight I cannot seem to get the scoop clear of the water
OK upwind but a disaster offwind
debating adding an uplift to the scoop
Any ideas ??

The stern of our SO35 does the same thing. I don't know that much could be done to prevent it as even when at rest, the stern scoop just touches the water surface. Out boot stripe is actually higher then the lowest point on the scoop.  With any sort of speed it becomes submerged as the boat drives forward and the water rises up at the stern in response to the bow wave.

You might try running with an empty aft water tak and full forward tank. We usually do the opposite though in an effort to keep excess weight out of the bow.

What do you have in mind for an uplift?

Have you put the WHOLE crew, or as many as you can up around the mast? While on my boat, it does not get the whole rear out of the water, it does help A LOT! I know of a few other boats that do the same.

This is a 'fault' in the design of all  boats. As boat speed increases there is a decrease in the pressure behind the fin caused by the shape of the hull. This decrease in pressure cannot be altered, whatever you do the hull will settle until you reach theoretical hull speed at which point one of two things happen. The boat starts to plane as the forward hull leaves the water and you start to overtake the bow wave.(the rear of the boat now becomes a surf board) Or the boat accelerates no further (Not enough drive in the sails) and the drag co-efficient of the rear of the hull sinking lower in the water prevents further acceleration...I.E. You have reached your maximum hull speed. If you want to go faster....double the power for half the speed increase!!

All boats 'suffer' from this problem. Design is always a compromise of so many different elements, nothing is perfect. But one thing is for sure, overall, Jeanneau Boats are designed and built by good designers and constructed by professionals. Nothing is without fault. Nobody is perfect. But I have to tell you my SO 40 is a joy. I never cease to marvel at her performance as I slug past bigger and fancier boats in those "imaginary" races that we all never have!, as we 'cruise to our destinations'. And at this point I remember the words of a Canadian trans-ocean sailor I once met. "Sir" he said "I don't race my house" And you know, I think he's right.... These are cruising boats, well made (not perfect) but up there with the best of the budget boats. Enjoy....what you have. I have just transited the Eastern Aegean in mine...just lovely.. two weeks at sea.

MY Jeanneau 35 is the opposite, down at the bow, comes write when we are in the cockpit, I often leave the forward water tank empty, I thought it was a design factor, compensating for the crew weight down aft.
