Hi Eric

thanks -

Noted the use of the Fox size spin which is 270 , luff length is the important aspect in determining the coresponding pole length and distance of hoist measurement available , 4 main things you can adjust -pole length -mast tang or spin lead location ,-mast rake {increasing luff distance }-or pole height.

On the earlier W-1000 N-6/0s with huge 450 spins trying to max them out , a 14 ft pole was used ,--an extreme mast rake was used ,-lead location set as high as structurally possible ,--and {to finally get to your question} we pre-bent the spin poles down as low as possible ,without having them stick into waves or larger seas,-{thugh mine sometimes did} -
The I-20 is set extremely high ,-this due to large end pole type snuffer that if submerged into surf or waves could lead to a capsize ,-when we use bare poles most bend them down abit ,--though {class rules} do not allow too much ,--which seems counter productive speed wise .

Hope that is helpfull -
