How to lift 21 Outrage

I found you guys in this web site are great, I have a question and hopefully will find somebody can give me some infor on how to lift the heavy boat.
I need to launch my boat from a small dock in
Point Arena in Northern California, what the harbor does is using a hoist to lift the boat from the pier and lower the boat into the water.
So, the question is, with my Outrage 21 (weight 4500# included full gas tank,motor and gears) can I use the lifting eyes for lifting, I afraid the lifting eyes will be pulled right out of the hull because it's too
Does anybody lift the heavy boat just with the lifting eyes, specically the new boats which tend to be more heavy.

Don't they use a cradle with their hoist?
My experience in putting in with a lift (Avalon, NJ)... the lift has what looks like two big strap swing seats. They slip the straps underthe boat, pull it up and dump it in.
I don't blame you for being concerned, but I do not know if it is a problem or not.

Hello!!! Your inside "eyes" will hold the boat just fine. If you would like I can make you a stainless cable and end "sling". We do it all the time in Sausalito with a davit to raise and lower a boat. Not just Whalers but racing sailboats and the like that weigh twice as much as your boat. The trick is in the hardware and custom sling. You`re pal in El Cerrito, Steve.

If you use slings under the hull, the
owner's manual has words of wisdom. As I
remember (manual is at home), if you do it
right, you are OK, you do it wrong you can
break the hull.
You can lift using the lifting eyes. The

Just curious, but with a lifting sling, what angle does the sling make with respect to the gunwales as measured to the common point of the sling?
Remembering High School Physics, the tension in the sling could easily be twice the weight of the boat if the sling angle was 30-degrees. (Sin[30-degrees]=0.5)

About 30 degrees.

You`re physics are correct but 30 degrees is pushing it. We`ve never had one let go. I will take some photo`s when I am over there and you will see first-hand what I speak. Stevo in El Cerrito.

I have launched my 18' Outrage there before. I borrowed a rope from the guy who runs the crane and tied it off to the two eyes on the stern and the single eye at the bow. Be ready to start and take off immediatly as the surf can be kinda rough. Bring a camera for some cool shots of your whaler hanging out over the Pacific. I sent some pics to Jim but he never posted them. Email me if you want some pics.

I remember those pics. I still have them, and I will try to post them.
I can't explain the exact science of how I select the pics for CETACEA, but sometimes it is a little unscientific....to say the least!
The older pics sometimes are lost in the electronic shuffle. I'll browse through the files again and see if I can find them.

Must be a different place Tom. The davit we use is inside the the Marina and it is always calm(although sometimes the wind kicks up). No surf to speak of. There is also one at Brickyard Cove on the Point Richmond side but I`ve never used this one because I do most of my fishing and boating on the outside. Steve.

Steve, Mihn was talking about Point Arena. Its a town up the coast north of Gualalla. You drive up on a pier and a crane drops you like 50 feet or so into the ocean. Great ling cod fishing there.

Tom- You had mentioned that you may have some pic's of your boat hanging from a crane. I would be interested in seeing them if it's not to much trouble. I love your boat, it's set up great for offshore running. I have purchased a 18 Guardian from our local marine police (stripped) and am in the process of putting it back together. I have 2 davits I mounted to my pier poles that are rated at 1850 lbs. each and was hoping to hang my outrage/guardian from them but wasn't sure how.
It sound like the forward eye inside, and the 2 in the stern (inside) would be able to hold the weight. Does this sound right? My guardian is listed at 1750 lbs. and will have a 150 yamaha on it. I will check with the mfg. of the davits, but my main concern was the eyes on the inside of the hull. Would it be ok to use a spreader bar for the 2 stern eyes? Any input would be greatly appreciated. One last thought, Each davit is rated at 1850 but the stern/motor davit will have more weight. Any way to calculate how much more? Perhaps CPD could shed some light on this. Thanks again, Eric

Thanks Eric. You dont need a spreader bar. Three big ropes work fine. I am going to test my boat with different sizes of nylon chokers one of these days. I have a forklift and several chokers in my companies warehouse to play with. I will post the results when I get it done. Guessing from a little experience I would say two 10' chokers in the back and one 16' choker in the front would be pretty close. Also need three shackles for the eyes. I would use nylon instead of steel chokers for obvious reasons. I'll find the pics and send them to ya.

Tom- You are talking about lifting from one common point like a crane, right? I have 2 davits, one for the stern and one for the bow with a 5 1/2 foot reach from the pier. I take it one rope for the bow and 2 for the stern would work. The bow length is not critical since I can adjust the height with the winch. The same is probably true with the stern. I was thinking of a spreader for the stren that way the tension would be pulling straight up depending upon it's width. There is a thread by Zach with some pics of his whalers that show something like I beleive you are talking about. Thanks for the input and I would still like to see the pics if it's not to much trouble. Eric

Yes I was talking about a hook on a crane. I sent the pics did you get em? . I'm not quite sure I know what a davit is.

Tom- A davit is like a small crane I guess you could say. Check out this site. I have 2 of these mounted to 2 of my pier piling about 20 ft apart each rated at 1850 lbs. Thanks for the pic,s I got em. http://www.davitmaster.com/boatdavits.htm

Ahh, I would love to have the bucks for something like that guys setup. Probably in Florida or somthing too.
