Well know the pain of the long winter wait as I closed the purchase on my 44 in November. I agreed the dealer could use the boat over the winter months as a display model and in turn the dealer kept the boat in their indoor heated showroom. I was also able to visit and "pet" the new boat a couple times a month until the spring launch. Also worked well for the boat tailors as they had a nice heated work area to construct the dodger and bimini also during this time.
end of summer for delivery is even more pain. If my situation I would be sending Jeanneau America staff bottles of wine, chocolates, fruitcakes, and whatever else for the Holidays along with a request to move up in the production schedule. LoL.
My prop wash comment relates to the effect on my rudder when Motoring. If I let go of the wheel the rudder gets progressively pushed to starboard. This is an effect on the rudder, not the boat initially. Locking the wheel negates the effect. But when unlocked and motoring tealeasing the wheel will soon have the wheel and rudder over hard to starboard taking the boat with it. Single rudder with saildrive.
