Bimini and Boom Rub

Post by FAAbaddog »

Folks,

Just spashed my 2011 26M today, awesome!

The bimini and the boom does not seem to work well and I am not sure if it is because I have the RF Main (from Mike Inmon's shop) and possibly a factory length to my topping lift instead of a shorter adjusted length topping lift for a standard boom?

Does this make any sense?

Looking for ideas please!

Thanks!

Are you saying the boom hits the Bimini when you have the main raised? If so ck the rake of your mast. You can cut the main bimini main tube down like I did with a worn streached main but your boat is new and should not hit the biminie when sail raised hard sheeting on main in tacking.

DaveB,

When I center the main for a jibe, the boom is pressing down hard on top of the bimini.

This just does not seem natural, I am thinking the topping lift should provide a 3 degree up angle and it's not so therefore the bimini forceful rub.

Thanks!

If the main in up then the topping lift should be slack and the sail should be keeping the boom off the Bimini. Make sure main sheet is loose and the boom free to rise when you hoist the main and that you get it all the way to the up. I added a small shackle to the tack grommet that lets the main be hoisted about an inch or so higher at the tack and moves the Clew up even higher. With the main up it should be clear of the Bimini even with the main sheet trimmed hard.

Fair Winds,
Mark

I do not have the roller furling main, so not sure if the support bracket is lower than the standard Mac boom. Is your Bimini adjustable? Mine mounts on the track and can slide forward or back. Too far forward and the front of the Bimini will angle up and hit the boom. Sliding it back will level it out or angle slightly down clearing the boom.

If all else fails, call Mike Inmon's shop and see what they have to say.

Congrats on the new boat Baddog!

I settled for a cdi on mast roller main but Mike's system was my first choice.

I would just ask Mike. likely though you will find you can just adjust your topping lift a bit higher without affecting the function of the main.

I have the same problem with the roller Main when I purchased my 26 :macm: from the factory last summer.
I just ASSUMED it was a lowered boom to accommodate the roller Main with the standard size mainsail.
I dont know any formal dimensions to help with the situation, so if you get an answer from Mike Inman, I can "fix" mine too.

On my 26X, I have a line that goes from the end of the boom all the way to the top of the mast. I find it quite convenient, as it allows me to adjust the height of the boom very easily, preventing any kind of rubbing against the leading edge of the bikini. It does not interfere with the shape of the main sail either.
