Bowsprit end hardware - cranse iron

[mauro.iachelli]

Hi All,

I'm in the process of building a bowsprit for my 1975 Amel Euros 41 ketch, I want her to have a double headsail to improve windward capabilities. My project is to have a 3' long (from stem) bowsprit tubular shape made in carbon fiber/epoxy (wall thickness 1/2") with a "defensive" fbg/epoxy outer layer of 3/16" . I'd like to keep a light 130% furling genoa on the main forestay attached to the cranse iron (1/4" SS316) and just aft to that (max 12" from eye to eye) another fitting to attach a movable stay where to set a Yankee sail. This second "band ring" will be welded to the cranse iron with two lateral bands of the same material to keep it in place and add stiffness. The piece will become one only. Now my questions are:
1) Do I need another bobstay for that? I 'd like to avoid it, if possible and I think the very close proximity between the two stays chainplates should allow that, but I'd like to hear the experts opinion.
2) Do I need to reinforce the linkage between the cranse iron and the second fitting with a lower band? I wanted to avoid it to let water seep through freely, but I understand that this is the place in which the bowsprit head will substain the most stress from the Yankee sail (in case I'm not installing a 2nd bobstay).

Thanks to all who can help.
BTW, I have a little sketch I can email for easier understanding.

All the best
Mauro
