Lifting

Hi,
I have owned a 1986 H16 for almost a year now. Living in Milwaukee, WI, I sail on Lake michigan out of the harbor. This requires dry-docking and this is where my question stems:
Does anyone have any experience raising/lowering/launching catamarans (especially H16's) on cranes? I did this quite a few times last year without much trouble. I rigged my own lifting harness using 4 lines connected to one carabiner which attack to webbing straps which hold each pontoon. However, this year I installed a Hobie Bob and have experienced much difficiculty with the boat blowing in the wind.... wanting to tip on the crane...ect. I am lengthening the ropes and hoping to change the center of gravity..... move it lower... but am wondering is there anything else which might lessen the effects of Hobies' terrible aerodynamics. The boat sails great but doesn't fly quite as well. I know this is kind of a strange question... and possibly a difficult one to answer but please give me any advice you might have.

Thanks,
Orion
