Dinghy davits and lifts?
 
We have a 2007 Mariner 40 Sedan that is similar to many of the Mainships. I am looking for options for dinghy placement. Currently, I lift our 10' Mercury light weight dinghy and 15hp Yamaha motor (separately) to the top deck with a Garhauer lift.
That works good, but I would like to be able to launch the dinghy more quickly when we are cruising with daily stops.
I've looked at davits like Forespar, and Kato as well as swim platform mounted like Trick or Hurley.

What is the preferred method used my you Mainship owners?

Thanks,

Weaver davits work well for me. See my avatar at the left. The Weaver davits are a pair of heavy clips, brackets (can't figure the right word, but I wouldn't call them davits) that attach to the back of the swim platform and mate up to a clip/bracket that is glued to the dinghy. They snap in and then you flip the dinghy up.


A real advantage is that when flipped down in the water, they keep the dinghy stable for loading/boarding. Then you just raise the catch lock and you are free.

They also make a device, the Weaver Lever, that the outboard mounts to which lets the outboard swivel and stay vertical as the dinghy swings. Haven't used one myself and I suspect that you need a light outboard and room for everything to clear as it swings up.

See https://www.weaverindustries.com/ for more info.

Another vote for weaver. They will work with you on the phone if you have questions.

Weavers are the best for simplicity and ease of use as long as you don't need access to the platform while the dink is up. Also need to make sure your dinks length does not approach the beam of the boat otherwise you can have issues with wave action against the dink.
They are also not recommended for hard bottom dinks IIRC.

:thumb: Agree - Weaver works well for me - had them on 2 boats now.

Our system is Jatco's Trillogy, side-loading, 125-lb dinghy and 106-lb outboard (+ starting battery), hand winch, no heavy lifting.


Not really visible in avatar, since we take most of the top parts off the swim platform during our fishing month.

I hated my weaver....it made the boat look well...like OCDiver likes to say...:D

I also didn't like the way it utilized the swim platform.

I didn't like that I couldn't store my engine on the boat and didn't want to fund the goofy engine tilt mechanism.

So I made my own for $300...will never look back. Still needs about $200 in mods to raise it a bit and make it even stronger (though it was great on this last 2000 mile trip).

I use the mast/boom with a power winch to raise & lower it...but other methods would be easy to rig too.

Scott, that looks awesome. If you added another cross member could it be used as a swim ladder as well or is it to far off the swim platform?

Too far off...but I have a nice pull down ladder.

What is cool is ...no matter how I approach by dingy...the bow person or just me can grab any portion of it and easily lift it so the dingy with all on board is now surrounded by the tubing...no more trying to snap the weavers when it is less than perfect conditions.

The nice thing is...in an emergency...anyone can cut the lifting rope and it falls a few feet into the water (it is on a pelican...but in an emergency why care)...it stays firmly attached until you release the pelicans holding the dingy to the bar, when ready just push away. Literally seconds if necessary.

There are pins that hold the bar to the transom so the mast/boom can be used elsewhere like lifting the motor on and off, or other things...but I keep it attached to help keep some weight off the total system and it keeps the side to side motion to a minimum.

I have an Roskelly/Olssen which very similar to transom models now made by Nick Jackson. Mounts to the transom instead of the swim platform. The hardest part of the launch/retrieve is getting in and out while hooked up because my dinghy is only 8'6". Easy to use and robust construction.

Scott: Can't quite tell how high the dinghy bottom might be off the water....have a guess? Are the hinge points directly over a support? What material type and diameter? I hate the look of a dinghy bottom for a stern (as on Weaver snap davits) and your approach is still convenient without blocking a waterview from the aft deck.

The bottom is about 2 feet off the water...good enough except for breaking waves astern...but no issues so far in any conditions most loopers would do.

The engine needs to have the lifting bridle changed a bit so I can tilt it...in the down position, some waves do hit it.

I should have told my buddy to bend it to 120 degrees, he just assumed 90 degrees and it does droop a few inches with the weight of the motor on the dingy.

It is 2 inch aluminum tubing and I am not sure what schedule...but small gussets will be perfect. The arms seem strong enough...it is the bends that worry me a bit long term. I am going to have him remove 20 degrees from the bends or just bend the tubing a few inches past the 90 bend . This will raise the dingy nearly a foot which will be perfect. 3 inch tubing would be the ticket for crossing an ocean...or go stainless...but for me the 2 inch will do.

The trick with the angle is having the dingy at a good height to put stuff in and out yet when lowered...be close enough to the swim platform to easilt reach and clip on without having to undo the hanging drops.


The supports are not directly over swim platform supports but with a dingy/motor combo under 200 pounds...didn't see it as an issue...of course the swim platform is critical if through bolting and strength aren't there.

Why dont you like the Kato (island) davits? They will fit your needs exactly.

Wmiii 04-03-2016 07:10 AM

Thanks for the ideas.
I have the Weaver brackets already on my swim platform, but with the weight of my outboard (135lb), I would still need to remove it before hoisting the dink.
I would prefer something that I could leave the motor on and be able to splash and retrieve quickly and easily. We use our swim platform for boarding when at the dock, especially a floating dock. So I would like to be able to remove whatever lift/davit I come up with.

I traveled with a Monk 36 that had a Sea Wise Davit System | Innovative and stylish yacht and boat davits system. You could still use the swim platform. Looks pricey.

mbevins 04-03-2016 08:56 AM

I also owned one of these on my previous boat.
Very easy to use . WWW.dinghycaddy.com

I am in the process of purchasing a boat with this installed. As such, I haven't used it yet myself. The current owner likes it a lot, although as he has the manual version, he says it is a bit of a workout to crack it up. I am considering modifying my Winchrite to use on it.

I liked it because it intrudes very little on the swim step and the outboard is left on, yet is stored vertically.

I had these custom built out of heavy wall tubing and bolted them to the transom . They're not the prettiest but they work . I need to add more blocks to make the lift easier . I think I have around $700 on them .

Russ Borman 04-03-2016 09:06 AM

We use the Weaver davits and love them, doesn't get any simpler. when were under way we pull the dingy all the way up against the transom. at the dock back her off a couple feet and you have full use of the swim platform. my wife loves it because with the dingy there she does not have the feeling of falling in the water. when down and clamped in boarding and loading is very stable. And works just fine with are hard bottom dingy'

Here they are on the boat . I've added better rigging since this pic but still not quite right .
