Electric winch for hoisting dinghy

I currently hoist my 9ft Caribe RIB aboard using the mast and boom for the steadying sail. I have a small 12 volt ATV winch purchased some years ago from HF, and I'm exploring the possibilities of using it to do the "heavy lifting". My plan so far is to locate the winch in the engine room almost directly below the mast with the hoist cable running in a conduit to deck level. Launching and recovering the dinghy requires the use of two halyards: boom up/down and hook up/down. The electric winch has power-up and power-down but only one drum. The remote control has a convenient plug/receptacle arrangement so it can be removed and stowed away when not in use.

If any forum menbers have done or considered doing something similar, what did you come up with?

Currently using weaver davits...will use same setup to hoist to regular stationary davits...have used it to swing dingy up on dock. Use 4 purchase tackle to hoist boom...

Now it's a lot easier with remote hand switch and winch to do things. Use winch to lower 80 pound 4 stroke onto dingy transom...now a snap.

The Eagle has two 2000 lb electric winches bought from harbor freight, 75 bucks/each with the wire remote up and down. One attached to the mast to raise lower the boom and one on the boom to raise lower the hook. The limiting factor of the lift is not the winch but the holding strength of the mast stays. I designed the new mast so winches could also be used to raise/lower the fish stabilizer arms.

Good info. What size cable did you guys use to get power to the winch.

The 12V car wire winches work fine for an amazing long time .

No repair , just toss it when it finally dies.

OP, the only drawback to your idea is the cable will bunch up on one side or the other of the spool unless you are in the engine room helping it wind in correctly. I've got the winch pictured on my atv and it works great. It gets wet, muddy and abused and keeps working. Good luck

Do the winches you are looking at have brakes to stop them "unwinding" under load? We have 2 winches mounted on our boom. We use this set up to adjust boom height and raise/lower dinghy. estimated weight is about 650lb, using 2,000lb winches.

I use a separate deep cycle battery. Why run cable for some thing you are use on occation. It most used a couple of minutes. I think the wires for the remote is 10.

For our davit, we have #4 wire from the batteries/solenoid (engine room) to the winch. The winch is a Warn DC1200-CF with a 1.3 hp motor that draws about 50-60 amps. The hoist capacity is rated for 1200 lbs. We lift the dinghy every night and the hoist/motor has never failed us.

I suspect there is a difference between a winch designed to pull an ATV and one designed for overhead lifting.

Before you take this plan too far, check the owners manual for the winch to see what it says about overhead lifting. Without a brake or safety device a stripped gear or such could let the load crash to the floor.

Sounds like that could be a problem. Does it bunch to one side when there is a steady load on the cable or only when it is slack?

BTW: Thanks to all who have responded so far; I'm taking it all in!

The Warn DC1200 has an automatic mechanical brake that holds full rated load according to the manufacturer. It is designed as a hoist and is very specific about how it is be mounted.

2000 Lb. Electric ATV/UTV Winch with Automatic Load-Holding Brake
BADLAND WINCHES - item#68146
.......
11. Do not use vehicle to pull on the Wire Rope and "assist" the winch.
12. Use as intended only. Do not lift items vertically or use for aircraft purposes.
13. Prevent entanglement. Do not wear loose clothing or jewelry, as they can be caught in moving parts. Non-skid footwear is recommended. Wear restrictive hair covering to contain long hair.

Larry: Taking into consideration the amp draw of the unit, according to the performance chart you give us the link for, and the length of the cable from engine room to winch, do you have a breaker/on-off or battery switch in the line? Where?

There's an 80 amp breaker between the batteries and the 80 amp continuous duty solenoid and a 10 amp fuse at the winch control solenoids (up/down). There is also a 10 amp breaker at the main panel for the master on/off.

I use a similar winch but a little larger (4000 lb) on a small s/s davit crane.
To save running wires to the Eng room I installed a seperate battery at the base of the crane and mounted a small solar panel over the winch so that the whole kabang is self sufficient.

Darned if that's not the spiffiest solution I've heard of yet. I have a swinging davit that I'm mounting right now, and I sure like the idea of an independent system like yours. My solar panels are only five feet away, and I've got room for a small one just to charge a separate battery. Short wire run....great idea.

Sailor,
Tinnys are mostly the favoured tender down here in Aus. Mine is an Edge Tracker Lite, bare hull weighs 75 kg and it is 3.7 mts ( 12 ft) long and pretty beamy. Goes like stink with a 15 HP on the back.
They can take a battering and not leak, easy to repair with a bit of epoxy in an emergency, don't come apart in the sun and crocodiles find them harder than inflatables to chew. (Inflatables , teething rings for crocs)
The inflatable tubes around the side are on sail trac and are made by a local co called Air O Float.
They make the boat bloody stable and easier to get in and out of when free diving or just snorkeling around.

Shoalwaters,
I think that's the same motor w planetary gears that is my anchor winch/capstan. Very noisy and not recommended for long periods of operation due to heat buildup. Mine seems to have plenty of power though.
