Re: New Mac 26 Roller Furling for Main

I have found that for trailering, the furling boom is as fast or faster for setup/tear down than a conventional boom and sail. I keep the boom on deck, about 3 ft from where it attaches to the mast. I raise the mast, attach the topping lift to the back of the boom, lift the front of the boom to the ...

Re: New Mac 26 Roller Furling for Main

I did not buy the furler separately. I bought my boat, 2 years old, from the first owner. Furler was installed when new. According to the price sheet from Boating Atlanta, main furling was a $2,990 option. Yikes... Looks like less than $1,500 worth of add-ons to the stock boom, including fab labor. ...

Re: New Mac 26 Roller Furling for Main

I own one of the furling booms. There were a couple of iterations of them. I know at least one other sailor that has one. Did you have a particular question, or just curious if they sold any? They did sell some of them. Basically an add-on to the stock boom. The sailingred furler is behind mast furl...

Re: New Rudder Build for 26S

Cool!

Looking forward to following your prototyping and testing.

If I remember correctly, the standard 26m rudders are approximately 0012 (just an FYI).

Re: New Rudder Build for 26S

You'll be the first boat in your area to sport a humpback whale fin for a rudder :D The study shows some interesting findings. I didn't find one with photos, and that same text though. https://arc.aiaa.org/doi/abs/10.2514/1.28497?journalCode=aiaaj Study was done in a wind tunnel also. Here's one don...

Re: New Rudder Build for 26S

Running downwind is a different animal. I assumed you were having trouble reaching and beating. What sails did you have up? If both main and jib, were you wing on wing? Did you have following or quartering seas? Depending on the conditions, running downwind can be a handful. If you could post a link...

Re: New Rudder Build for 26S

You can look around the net for real rudder design info. This is a fairly detailed article on keel and rudder design. https://www.ericwsponberg.com/wp-content/uploads/keel-and-rudder-design.pdf I would stick with a smooth NACA foil shape and have around 17% max of the rudder area ahead of the pivot ...

Re: Discussion about Traveller's, Heel, and something I am confused about

I am trying to think about where to put a traveller on an X - over the cabin top, or across the sette's aft. Would either location matter wrt sailing performance? Ed To this part of your question, I would say the cabin top location would be better. The traveler would be functional over a considerab...

Re: Discussion about Traveller's, Heel, and something I am confused about

On the bright side, you seem to have a firm grasp on the rest of it. :( Internal vs external forces/moments seems to be snagging you.

Re: Discussion about Traveller's, Heel, and something I am confused about

Well, Tomfoolery covered it in detail above, but basically nope.

The traveler and mainsheet change heel through sail trim/movement of CE; not through moment induced through the connection point.

Sorry :)

Wish you had saved me a beer!

Re: Discussion about Traveller's, Heel, and something I am confused about

Just to clarify the question: Ed, are you wondering if attaching the main sheet at cabin top will increase heel; and conversely, attaching it to the bottom of the keel would reduce heel (absurdity for purpose of illustration). Is your thought that the main sheet pulls on the attachment point creatin...

Re: Rudder Repair

Yeah, crazy leverage forces. Jimmy T's solution looks like the way to go, maybe w/ a truckers hitch to keep it as tight as possible. Now to just figure out how to fix. 8 years of highway bouncing to overcome, or maybe I should move to the coast? 61 deg F, blowing 9 out of the east. You could be sai...
