hoist launch C-26

Has anyone set up, or has a C26 configured to launch from a hoist?
Our harbor has a crane that makes launches really easy. I sail with a friend a lot that has an Olson 30 that we launch with it all the time.
The crane has a 2.5 ton limit, and I think the C-26 might be close to that.

On my C-26, there is a ring attached to a board on the aft portion of the dining table/keel pocket, and that board has about 20 screws securing it. It looks really strong, but I don't think it would be strong enough to hold the weight of the boat. Anyone know what it might be used for?


Thanks

When I had the J-24 the whole fleet was drysailed and launched with a crane BUT the J24 had a purposebuilt lifting eye attached to the keel inside the bilge..... I think that is the best way to safely lift..with a lifting eye attached to very solid keel bolts. I can't think of any other single point on the chrysler that would be strong enough to hold her from above.



At my yard they lift with slings and a travel lift BUT I have seen a fitting ( like a huge "H" bracket with slings hanging down ) for a crane that allows the crane to lift with slings. I could imagine you could fashion your sling with strong lifting straps and chains that all collect in the center with a single bridle and provide a single lifting eye for the crane...

If you have the fixed keel ( like I do) buying a trailer and floating her off with a ramp is a very hard thing...I am not sure how much water we would need at a ramp to float off a fixed keel. So I use the travel lift at great expense.

I also think we ( c-26) are heavier than 2.5 tons....

I have considered a harness. My boat is currently hanging in my driveway in a harness of chain wraped with blankets. here is a pic: Image
I am in the process of completely redesigning my trailer. (I am considering posting the process here).


Routing a harness for regular use would be a pain. I would prefer to attach to the keel bolts, but I don't even know how to get to them. On the Olson 30 that I mentioned, a loop of 1" thick rope is attached to the keel bolts. The Olson 30 has a displacement of 3600lbs.
One nice thing about the C26 is that it has such a large hatch, so running cables or rope down inside should be easy.

Has anyone ever had thier C26 weighed?

Dry the displacement is 5000. I figure you can add another 750 for provisions.

WOW! how did you lift that!

I would love info on mod'ng a trailer for a C26 ( although I have the fixed keel) .. I see you have triple axles!

Also I think the swing keel is heavier than the fixed keel but these are very heavy ( and strong) hulls.

I couldn't advise you on fitting a lifting eye but I would think the strongest part of the boat is where the keel is attached, that is very heavy and represents most of the mass you will need to hoist.

I probably should start another thread for this, but...

I lifted the boat the easy way. I used a neumatic 10 ton jack and lifted both the trailer and the boat to the desired level, slung the chains underneath the hull, then lowered the trailer back down.
It took a couple of hours, since I would alternate lifting the front up about a foot, and block it, then do the same to the back. The process would work with a couple of 5 ton floor jacks too, one on each side lifting together.

hmmm.... got me thinking... I have to replace the bearings in my rudder shaft...the conventional way is to dig a deep hole....back breaking ... and I am not sure the yard would be happy about a big hole ( they would love for me to rent their travel lift for this work at god knows what an hour)....but... if I lift her transom by jacking up the rear of her wood cradle....and tilting her ever so slightly forward....I wonder.... ( I really do need a trailer )

I like all those adjustment points on the trailer...hey..how'd ya get the topsides so shiny?

Nice Boat

Hi. My C-26 is a 1979 swing keel, that has not been in the water over 16 years. So I am no expert on C-26's. But I would never try to lift the boat with a singal hook up. Two straps, or lonch of your trailer. Is your boat a swing keel?

Yes, my c26 is a swing keel, as seen in the pics.

This all may be a mute point, since the weight of the boat appears to exceed that of the lift at my habor.

Most of the boats using the lift have a single attachment point, though the Olson 30 has a few additional attachment points, but they are for balance, rather then supporting any weight.

My boat came with it's shiny coat.

Nice shiny coat for sure...

curious, if you get a chance I would love to know the width of your white cove stripe and the width of your white boot ( waterline) stripe.. I have never seen the proportions look so "right" -- thanks

NYC -

The upper stripe is the easy one: 1" all the way around, except at the bow, where the extreme angle makes it 1 1/4".

The water line changes drastically as you go around. At the very bow, its 3 1/2", but as you go back, it tapers to as little as 2 7/8". Amidship it's 3 1/4", but as the line goes under the stern, it gets as wide as 11 3/8".

I suppose that you could use 3 1/4" as your baseline and work your way forward and back from amidship, and use some sort of square to keep it consistent as see from the side.
