A boat davit is a lifting and launching system designed for boats that weigh up to 11,000 pounds, such as jet skis, dinghies, and other watercraft. These crane-like devices are used in restricted conditions like no pilings allowed, seawalls only, or the presence of rock bottoms. They consist of one or two stainless steel supports equipped with hoists, and can be attached to sailboats or pontoons.
Boat davits come in various shapes and sizes, suitable for all weights of tender and yacht designs. They work in shallow water locations, narrow restricted locations, rock bottoms, and locations where pilings are not permitted. Boat davits are an economical alternative to standard boat lifts and are easy to install. They are available for seawall, dock, or pile mounts and come in pairs and three different sizes: 50 kg, 100 kg, or 150 kg.
The HMC Davit is a machine-like object used to help people on decks of ships and boats. It is made of aluminum alloy, making it light and resistant to corrosion. The davits come in pairs and come in three different sizes: 50 kg, 100 kg, or 150 kg. Two types of fittings are offered for both straight or angled sterns.
In summary, boat davits are essential lifting devices for boats that weigh up to 11,000 pounds, providing a reliable and efficient solution for handling heavy equipment. They are available in five models, each with a choice of manual, electric, or power pivot options.

What is a rescue davit?
Davit arm systems are commonly used to raise, lower, and suspend personnel performing routine work duties or to facilitate rescues in vertical confined space applications such as vaults, manholes, and pump stations.
Anchor Points. Pre-engineered or custom anchor points for many different applications.
Cable-Based Lifelines. Horizontal and vertical cable lifeline systems, for travel restraint or fall arrest.
Catwalks. Provide safe and easy access to elevated work stations while mitigating fall hazards.
What is a davit arm used for?
What is a davit arm system?. Built from structural aluminum and steel, a davit arm is a crane-like fall protection suspension system used to safely lower and raise workers and/or equipment from heights or in confined spaces, as well as serving as a critical tool for confined space rescue.
Davit arms can be temporary or permanent depending on the work site and job needs.
Why is a davit arm system essential to fall protection?. The davit arm is engineered to provide an offset overhead point for the mounting of a personnel lifting, lowering, or retrieval device and/or a personal fall arrest system.
What is the difference between anchors and davits?
Are roof davits the same as fall protection anchors? No. Roof davits are designed to have the capability of suspending scaffolding or personnel from the anchor to safely work on the face of a building. Rooftop fall protection anchors are designed to protect a worker from falling off the building.
Roof davits and tie-back anchors are used during exterior building maintenance to the exterior façade of a structure, such as window washing, caulking and painting. These anchors are capable of withstanding an ultimate load of 5,000 lbs in any direction per Cal/OSHA Title 8, 3291 to allow for the suspension of scaffolds or Bosun chairs.
Our roof davits are trusted by building owners throughout California. We guide you through every step of the process from initial consultation to engineering and installation, all while ensuring you have the proper test documentation per Cal/OSHA Title 8 requirements.
Buildings 36’ tall or 3 stories are required to have roof davits (tie-backs) unless you can achieve window washing and unscheduled maintenance from ground-based equipment. At 48’ or 4 stories, you must provide them regardless of ground-based equipment capability.
How does a boat davit work?
Pull-Up, Slide-Up Davits. These davit systems offer a low-tech approach to handling the dinghy. The pull- or slide-up davits have two hinged cradle arms mounted onto the swim platform. When you want to get the dinghy aboard, the hinged arms tilt out to the water from the swim platform, and you pull the dinghy sideways onto the cradle arms.
Pull- or slide-up davits work best on boats with wider swim platforms, and allow you to leave the outboard in place.
As the center of weight comes aboard, the hinged arms come back to rest on the swim platform and the dinghy is then secured with straps on the swim platform. The outboard doesn’t have to be removed. These davits can be used on most swim platforms wider than 18 inches and work best if the top of the swim platform is relatively close to the water. If the platform is too high, it can be difficult to manually pull a dinghy aboard. An electric winch can be used to accomplish this on some vessels.
What is the dead man handle on a lifeboat?
Unfortunatly there are lots of different designs of Davit around nowadays……Some are still fitted with a “Deadman’s Handle” type of Brake. This has a lever that has to be lifted to disengage the brake and allow the boat to descend. The lever is fitted with a heavy weight that will pull the brake on if the handle is released.By use of ratchets an Electric motor can hoist the boat up, while the brake will prevent it falling.
Others are Hydraulically operated and the system is designed to “Fail Safe” so that the boat will stop if there is any loss of Hydraulic pressure. Similar to cranes.
A lot of Electric motors on Cranes, windlasses, ER hoists, hatch covers etc are fitted with an electromagnetic Brake. These are spring loaded into the on position. When power is applied to the motor a coil is energised pulling the brake off. This ensures that the motor can only turn under power.
Why is it called a davit?
Etymology. The word davit is derived from Middle English and Old French daviot, which is a diminutive of David; thus it means “little David”, maybe because those small cranes can handle a much bigger lifeboat.

1912, Morgan Robertson, The Wreck of the Titan: Or, Futility:
A solid, pyramid-like hummock of ice, left to starboard as the steamer ascended, and which projected close alongside the upper, or boat-deck, as she fell over, had caught, in succession, every pair of davits to starboard, bending and wrenching them, smashing boats, and snapping tackles and gripes, until, as the ship cleared herself, it capped the pile of wreckage strewing the ice in front of, and around it, with the end and broken stanchions of the bridge.
What is rescue boat davit?
Marine. Usually hydraulic operated slewing or pivoting davits designed for launching and recovery of a fully-manned rescue boat against unfavourable conditions of trim of up to 10 degrees and a list of up to 20 degrees either way.
Usually hydraulic operated slewing or pivoting davits designed for launching and recovery of a fully-mannedrescue boatagainst unfavourable conditions of trim of up to 10 degrees and a list of up to 20 degrees either way.
Slewing out of the rescue boat from its stowed position into launch position is performed by means of accumulated power obtained from a hydraulic power pack. The slewing motion is actuated within the rescue boat by means of a remote control pull wire.
Lowering is done by means of gravity. The lowering motion can be controlled in two ways: either by a remote control pull wire within the rescue boat or by lifting the brake handle of the winch directly. The recovery of the fully-manned rescue boat is accomplished by the electric winch. In case of a power failure or malfunction of the electric system, hoisting can also be done manually by the crank handle of the winch.
What is the primary advantage of a davit?
Today, the various boat davit systems are used for lifting, launching and storing inflatable tenders on motorboats, sailing boats and yachts. A davit or boom allows the dinghy or other heavy load to be manoeuvred without too much effort.
A davit also allows the dinghy to be held at the stern of the boat while underway to conserve space on the boat’s deck.
The different types of davits and load masts. Davits have evolved over time. First, there was the swivel or “coat rack” davit. Then came the oscillating davit, then the gravity davit and finally the most common models we know today.
What is the primary advantage of a davit launched?
What is the primary advantage of a davit-launched liferaft in comparison to an inflatable liferaft? The davit-launched liferaft enables personnel to enter the raft without having to enter the water.
📹 We found the PERFECT DAVITS for our dinghy – Ep. 202 RAN Sailing
This is our last project before we start our summer cruise. We’re going to mount davits on the boat! We are a Swedish couple who …
I very nearly bought a bought in Sweden this last winter that had those same davits… I really liked them – quite simple and lightweight. On that boat, the owner had rigged a common line as a “Y” to each of the davits back to one of the motorized winches so you basically just clipped the dingy on to the tethers with snap clips and pushed a button and up it went slick as cheese. Yours looks like a two person effort at least until it clears the swim platform but that’s no biggie.
The new dinghy and davits system is going to make life so much easier for you moving around with Vera. I vote Vera for the cutest little YouTube baby of the year. She is so sweet. I think she quieted down when you started the motor because she remembered the noises from inside Mama before her birth. Can’t wait to see more of your adventures.
Johan nice job on the Davits! This was a nice upgrade that will serve you well as you start your cruising season. Well done! May the sun shine on your face and the wind be at your back. So enjoy your articles and the drone footage has been outstanding is past articles. Love your website. Malin and Vera you two are so cute. Enjoy your crusing season!
Funny….as you were drilling that first hole, I was wondering if you would need to drill it oversized, fill it with epoxy and then drill the proper size hole. I’ve watched your neighbor (Mads @ Sail Life in Denmark) do that several times on his boat. Then, you answered the question…solid glass, so you don’t need to seal with epoxy. Man, I’ve been perusal too many sailboat articles on YouTube!!!
When you design the arch, maybe it will be an option to raise and lower R2D2 with one pulley system, so you can control it from one point and not have to move between the two davits. That might make it easier and faster to raise and lower the dingy. Like others suggested, don’t hang R2D2 to level, so the rain water can drain out, avoiding an extra load on the davits.
Great job installing the davits, well thought out measure twice drill once it will be much better as you say when you install the arch and lift from there. The two of you seem to work so well together towards a common goal, it’s a real joy to watch your articles, beautifully put together, well done. Congrats on the 100K subscribers.
Nice article guys, really good to see the install, I am installing an anchormatic windlass at the moment, I also know the measuring difficulties . We have been thinking about buying the same davits from båtsystem, but we are also thinking about building davits into the arch later on when we install that also…. tricky decisions. Seems like a great solution though. Cheers from Chris and Tanja in Stockholm
Maybe I’m just overly paranoid but the skinny lines that connect the dinghy to the carabiners make me nervous. Chafing will do a quick job of it. In addition the fact that it just goes through makes me think that there’s nothing preventing the dinghy from tipping over as these lines slip through from side to side.
Hi, I saw Vera wearing a very professional life jacket . Please can you advice the brand and where can I found it? I have a son of 9 months and a small sailing boat and I want bring him with me this summer, hoping that Corona virus will allow us to go out from home . Thanks in advance . Regards Giuseppe
Assuming there’s some way to rig another extra halyard to the masthead, I feel like this setup is crying out for a one-line hoist. Only thing, is you’ll need a cross-bar of some sort added in, to keep your davits from pulling inward toward each other, if you use my idea of a split-pennant/sling raising both davits simultaneously from one halyard. Or maybe if your crossbar was strong enough, you can hoist from one point in the center of that. Yes, either way it means another line from the masthead, but the actual hoisting I think would be faster. And yes, obviously you could also just repurpose your main halyard each time… You won’t usually be departing in the dingy with the sails still up. But re-shackling the main all the time is another problem. Without knowing the exact specifics of every sheeve on your boat, the only other option I’m thinking of, is if there’s a “topping lift” halyard available already rigged (but not often in use). That or whatever else you’re already using to get the dingy on the foredeck. But that’s presumably in front of the mast, and not a good lead for hoisting anything aft.
Congrats on the 100,000 subscribers.. Been following from the beginning and enjoy each episode.. Just curious if you could take a few minuets to show your rigging? The back stay is very interesting and I am very curious how it may differ from other boats. I can see on the sides large pipe like sections on the side stay shrouds.. Why do some boats have these larger sections while others do not?
Congratulations on the 100.000 subs! You’ve deserved it and I hope you’ll reach the next milestone soon. Johan, the davits look great! I thought that if you connected the two towing lines into one, somehow, you could pull the dinghy by just pulling at one rope. Just a question: Would it be possible to remount the steering wheel into the enclosed cockpit, like on SV Delos? It would mean a lot when in bad weather.
Nice job guys; on both the davits and the 100k subs..! I was thinking though, do you think you’d be able to use the Topping Lift (or an equivalent halyard) to haul up the davits/tender using an electric winch..? Also, I was thinking that if you flipped the block-and-tackle arrangement – so that you’re hauling on the davit arm as opposed to the push-it – that you’d get more leverage… what do you think..?
Hi there, thank you for all you send via youtube! I need a platform as well and looking to batsystem, too. And I am wondering, that you don´t install one of the foldable ladder (BA-BKT73, BA-BKT74) to have more space on the platform? What´s wrong with these or which detail could be bad to use? Your ladder can´t be unfold / used, if the dinghy is hanging up and blocking the ladder, isn´t it? So could be a risk, if someone need to get on board quickly? Thank you for your thoughts to the foldable ladders 🙂
A mother and her daughter. No words…. You are not the first: my wife breast fed our daughter in full day time, in front of the main church, with compliments from passers by. It was another era, much, much more easier on people and menthality and hope for a better future: summer 1980, Monfalcone, Italy.
