Right you are! I think the spin hoist/retrieval systems being used are designed for sloops. I use the single line system with spin lock (which I love), but it just seems awkward, even after all this time.
I don't know how it'd be done differently.
I started standing while hoisting, you can really rip on the halyard then.. The boat wants to round up just a little bit, once the spin is out of the bag it seems to balance out nicely until I can get hold of the tiller again.
