I've got a couple folding padeyes coming, and planned to mount them each side of the companionway, on the backside of f110. I'll put in the appropriate backing and reinforcement of course, but I'm curious what others have done to make their boats hoistable?

..it sounds like those would be good for primary load,,with some lines going fore/aft for balance.
..if part of the lifting bridle attaches to the keel-lift,you'll be taking about 1/4 load from the hull-lift points as well,,which would also be helpful

Yeah, I'm pretty sure the CG is a little behind f110, so a couple strings to the kite blocks for balance, is what I planned.

I have some short slings for lifting the hull here in my shop, but for launching from a hoist I'd need longer ones with an additional pendant or something for the keel, like you said.

I think DBSS did something for hoist launching, I'll go check his pics next.

From DBSS:

The boat is lifted via Two Wichard pad eyes on the main bulkhead just eitehr side of the keelbox. We added some reinforcement to the inside of the bulkhead during the build for this. Lines also go to the kite block fittings.

Not sure from that if he's using f110 or f124...

I believe DBSS is the long cabin short cockpit version. Attachment points were probably at 124. Hopefully I'm not misleading you on this.

Naw, he's a long cockpit jobby, same as me.

It's no biggie either way- it'll just take more tension on the aft lines if attaching to f110 turns out to be too far forward.

...big-time SHOP-ENVY when I see pic's like this

And here's Ron's boat, hoisted by a bridle to the chainplates and some lines aft to the kite blocks. CG looks pretty much mid-keel, whether the keel is attached or not.



From this blog posting.

I use the chain plates (I have 1 spare hole on each side at the moment), which are maybe 2" forward or frame 110 with my 30 degree spreader angle, and the main sheet bridle pad eyes at the stern (spin turning blocks will do the same job). Mine bridle is made of used static climbing rope so it's not what I would call the lightest possible bridle. I've only hoisted sans rig as I ramp launch mostly. I can't find the picture I had of the boat up on the lift. I know it's in that folder somewhere.

Mast raising, sail measuring, and solo boat flipping, super fast like thanks to the time-lapse app I bought for my phone.

Nice video. Also, your roll-over cradle is very clever.

Chad, love the cradle as well. One note is that you do need a 2 car wide driveway . Certainly was a low drama event.

On lifting bridle points, If I was always hoisting the boat to launch it I would change my setup to use 2 points farther aft and then the bow. The boat wants to balance on or about frame 110 so it's not "stable" on the hoist. A wider bridle would allow you to get the lifting point right over the keel and limit the bouncing and pivoting that I've experienced. Last thing you want is your rig bouncing into the lift as you swing the boat around.

It felt a little sketchy as I walked around the transom, since I needed to change from pushing one way to pushing the other, and recognizing that it's really hard to pull on something that's over 8' tall. So I had to be very careful to balance it on edge as I walked around and gently transition from pressure on one side to pressure on the other. It was easy to do, but still elevates the heart rate a little...

I plan to ramp launch mostly, but wanted to have the eyes available to lift the boat when that was appropriate. Turns out the eyes are also good spots to attach the forward end of the foot straps.
