I know in The Practical Junk Rig, it says two masts could be used on a minimum of a 28 foot boat, and I think later it says if its LOA is over 31. My Cape Dory 28 has a LOA of 28.4. As I have had problems finding a good aluminum mast, and am now looking more into wood. I would prefer to have two shorter wood masts for back up,and easier to built smaller masts, havent done the numbers yet, but they should be pretty short, not sure how that would affect the performance in between tall waves maybe..no clue.
Other than mast placement vs interior space , does anyone have any thoughts on this. I will try to do all the figures this coming week , finding the mast placement and height , sail area, etc this week, I just thought maybe someone might have a reason I shouldnt even go down that road..lol.
Thanks
