Ahoy Aaron,
I don't know the answer to your cruising spinnaker question because I don't have one. I do have some numbers that may be helpful however.
I have 2 tri-radials that are both 168%. Remember that 180% is a "regular" spinnaker for non-bowspritted boats, but this number doesn't work too well on a bowspritted boat. My spinnakers measure 1157 sq ft.
The formula for cruising chutes is slightly different due to the narrower head, angled foot, and flatter cut. Assuming a 150% for the cruising chute, the area would be 861 sq ft.
Your friends 580 Sq ft chute would certainly work, and price is a big determinant, but it will be smaller than you could use.
Good luck, Dave
