Avocet's a very traditional long-keeler, not unlike a Folkboat, in fact. Like many of her kind, she's never gone the same way astern twice in succession! Springing off is possible, but (also like many of her kind) she is low powered and very narrow in the beam, so if there is anything more than a Force 2 blowing on to the pontoon (or any kind of tide pushing us on to it), FORGET IT!
The only thing that has ever helped is to try and build up prop speed VERY slowly. If I cast off and whack the throttle open, the prop walk seems to be the dominant effect. If I put the boat astern under a very light throttle opening and start to establish some sort of flow over the rudder and THEN cast off, she seems a bit better behaved (but only a bit)! Of course, we can do that with only 12 HP and a 3 ton displacement. You'd probably loose fingers with 10 tons and 85 horses! For us, if it's at all tricky, warping in is usually the way to go - but that's with only 3 tons. I appreciate it might not be so easy on a big boat.
