[quote=MN3]lowering the bridal improves performance and stability and sometimes sheeting angles
but at the risk of adding forces to the hulls
adding a bridal foil is a cheap, easy and light way to reinforce your hull strength and increase hull rigidity - which is a very beneficial thing to do, and for the cost... the insurance to your boat seems very worth it to me
"So far, these 30+ year old boats are staying together."
how many 5.7, 5.8. p19MX with bigger jibs and no foil have you seen survive?
I've heard of boats failing without a foil
nothing like hitting a big puff and a bow ripping off your boat a dozen miles offshore in the atlantic (happened to a friend of mine)
If you look at all the modern, cp designed sailplans - the jib is lower than the boom

[quote=Edchris177]I'm not sure I understand the reasoning for this mod.
I get that a foil changes the bridal loads to a "better" angle.
So far, these 30+ year old boats are staying together.
I really don't think they can be made to go any faster, or point any higher, at least not to any degree in real world sailing. The fact is, a skeg hull has reached it's potential, & we will always be beaten to booms & boards, given equal nuts behind the wheel.
What is the point of lowering the jib any further?
The jib mainly acts to accelerate air over the lee of the main. If the 5.7 is properly setup, the jib foot is level with the mains foot, giving the most help it can. Dropping it below the main gives some of that up.[/quote]<!-- editby --><em>Edited by MN3 on Jan 08, 2018 - 10:07 AM.</em><!-- end editby --> [/quote]
