Dinghy Davits

What dinghy davits are and why they matter

Dinghy davits are the fittings, arms and lifting hardware used to carry, raise and lower a tender from the stern or transom of a sailing boat. They make it possible to carry a dinghy clear of the deck or coachroof, keep the cockpit and deck space unobstructed, and provide a repeatable, safer method for launching and recovering a tender than manual handling over the side.

On many cruising boats a dinghy doubles as essential transport to shore, a platform for fishing or diving and a safety boat in anchorages. How you carry and handle that dinghy affects daily convenience, crew safety, vulnerability to weather and motion, and the loads placed on the boat’s structure. Davits range from simple padeyes and halyard arrangements to powered lifting arms and full gantry systems; the right choice depends on boat type, dinghy size, crew capability and how the boat is used.

What this category includes

• Fixed and folding stern davits — rigid arms mounted on the transom or toerail for supporting a tender.
• Gantry and A-frame systems — taller structures spanning the stern to support heavier tenders or outboards.
• Swing-away or swinging davits — designs that pivot the tender clear of the stern for easier boarding or better prop wash clearance.
• Electric and manual lifting winches integrated with davits — for raising and lowering the dinghy.
• Padeyes, lifting slings, cradles and roller systems supplied as part of davit kits.

This category excludes unrelated lifting gear such as mast-mounted mainsail halyards, general-purpose deck cranes not configured for tenders, and trailer-specific fittings. Accessories like chafe pads, cover supports and locking pins are commonly sold alongside davits but are considered ancillary.

Where and how davits are used aboard a sailing boat

Davits are normally fitted at the stern or transom. They may be permanently installed or removable, and they are used to:

• Store the dinghy clear of the deck while underway.
• Lower or retrieve the dinghy alongside while at anchor or alongside a quay.
• Provide an elevated mount to carry outboard engines above the waterline.
• Free up cockpit or foredeck space that would otherwise be taken by a tender.

Main product types and configurations

Simple padeyes and sling with halyard

How it works: A halyard or dedicated lifting line runs over stern chocks or padeyes and supports the tender with a sling.

• Advantages: Low cost, light weight, removable and easy to stow when not in use.
• Limitations: Labour‑intensive to operate, less controlled recovery in waves, and hard on liners if not used carefully.
• Best for: Small dinghies and boats where weight and simplicity are priorities.

Fixed davit arms

How it works: Rigid arms bolt to the transom or toerail and support the tender on cradles or slings. Some fold when not in use.

• Advantages: Straightforward operation, solid support underway, and quick deployment.
• Limitations: Adds weight and windage behind the boat; transom reinforcement often required.
• Best for: Coastal cruisers carrying modest-sized tenders.

Gantry and A-frame systems

How it works: Taller structures that provide greater clearance for larger tenders and outboards. Often include winches and rollers.

• Advantages: Handle heavier loads, enable cleaner stowage and easier boarding from the stern.
• Limitations: Significant weight and cost, may affect yacht balance and hydrodynamics.
• Best for: Larger cruising yachts or liveaboards carrying heavy rigid dinghies or multiple engines.

Swing-away davits

How it works: Arms that pivot the tender clear to one side for boarding or to reduce exposure to following seas.

• Advantages: Easier access to cockpits, ability to move the tender out of prop wash.
• Limitations: More moving parts and alignment issues; clearance off the side must be checked for marina berths or alongside situations.
• Best for: Boats where stern access and prop clearance are important.

Powered lifting systems

How it works: Electric or hydraulic winches integrated with davits offer powered lift and lowering, sometimes with remote control.

• Advantages: Low physical demand, fast and controlled recovery, useful for single-handed crews.
• Limitations: Requires electrical or hydraulic supply, higher complexity and maintenance, potential single-point failure unless manual backup provided.
• Best for: Cruisers who frequently launch and recover the tender, or those who anticipate lifting heavier tenders.

Decisions that matter before buying

Choosing davits is not just about matching a headline capacity — it’s about the interaction between the boat, tender, crew and intended use. Key factors to evaluate are:

• Boat size, transom structure and hull type: Smaller boats have less margin for weight and windage. Confirm structural reinforcement, backing plates and through‑bolts are suitable for the loads a davit will impose.
• Dinghy size, type and weight: Include motor(s), fuel and typical equipment. Inflatable tenders, RIBs and fibreglass tenders have different hull profiles that influence cradles and slings.
• Crew size and strength: Manual systems suit able crews; powered systems assist small crews or singlehanders but require power and controls.
• Intended use: Day sailing emphasises light, simple solutions; coastal cruising needs dependable, repeatable systems; offshore use raises the importance of secure lashings, and prevention of accidental loss at sea.
• Storage and deck layout: Check clearance when the dinghy is stowed — above the pushpit, interfering with radar, solar panels or swim platforms.
• Power availability and electrical compatibility: Electric winches add convenience but must align with the boat’s electrical system and include adequate circuit protection and cabling.
• Installation access and maintenance: Ability to reach bolts, pivot points and winches for routine checks and repairs while ashore or afloat.

Understanding common specifications and terminology

• Rated load or working load limit: The manufacturer’s stated maximum load the davit can support in normal use. Important, but ensure margin — the real mass includes outboard, fuel and kit.
• Breaking load: The load at which the system will fail. This is typically much higher than the working load and should not be treated as the safe operating limit.
• Reach and clearance: How far the arms extend from the transom and the clearance under the tender when stowed. Essential for avoiding interference with equipment and for boarding geometry.
• Folded profile: The dimensions and projection of the davit when folded; key for marinas and berthing where beam and height constraints matter.
• Power rating and current draw (for electric systems): Helps determine whether the boat’s batteries, alternator and wiring are adequate. Quoted figures can be misleading if measured under ideal conditions.

Always measure your tender fully loaded and the proposed mounting points on the boat before comparing numbers.

Compatibility and installation checks

Before purchase, verify:

• Structural backing and mounting locations on the transom or pushpit. Many installations require backing plates or reinforcement to spread loads into the hull structure.
• Clearance from steering gear, swim platforms, boarding ladders, solar arrays, antennas and stern lazarette lids.
• Electrical supply and cable routing for powered systems; correct circuit protection and manual override provision.
• Whether the design will allow safe recovery in the sea states you expect to encounter — some systems are difficult to use in a seaway.
• Access for servicing winches, pivot bearings and fasteners while on passage or at anchor.

When in doubt, consult a rigger, boatyard or naval architect to assess load paths and structural reinforcement needs. A technically suitable davit can still be a poor choice if it cannot be mounted and operated safely on your specific boat.

Day sailing, coastal cruising and offshore considerations

Day sailing

• Prioritise lightness, simplicity and quick removal for storage ashore or when racing.
• Smaller dinghies and simple sling arrangements are often adequate.

Coastal cruising

• Require durable, repeatable systems that handle frequent launching and retrieval and protect the dinghy under a variety of conditions.
• Powered or well-designed manual davits with secure stowage points suit cruising couples and families.

Offshore and remote cruising

• Place higher value on redundancy, positive locking, corrosion resistance and the ability to lash the tender securely for heavy weather.
• Consider whether the system can be repaired with spares that are likely to be available while cruising offshore.

Trade-offs to expect

• Simplicity versus convenience: Manual slings are simple and light but require physical work. Powered systems are convenient but add complexity and potential electrical dependence.
• Weight versus strength: More robust gantries carry larger tenders but increase stern weight and windage, which affects trim and performance.
• Permanent installation versus portability: Removable systems preserve resale value and reduce drag but may be less rigid under load than a properly bonded permanent installation.
• Features versus maintainability: More moving parts and integrated electronics increase the points of failure and servicing needs.

Maintenance and service life

Routine care extends service life and reduces failure risk:

• Inspect pivot points, shackles, fasteners and welds for corrosion or fatigue.
• Clean salt and grime from bearings and winch gears; lubricate where manufacturer guidance permits.
• Check shackles, slings and webbing for chafe and replace consumables before they fail.
• Test electrical motors and emergency manual overrides; ensure circuit protection is intact.
• Store removable components ashore where possible during long periods of non-use to reduce UV damage.

Consider carrying spare fasteners, a backup lifting line, and basic bearing or winch spares on extended voyages.

Common mistakes and how to avoid them

• Buying by headline capacity alone: If the stated load doesn’t include the outboard, fuel and gear, the davit may be underspecified. Measure actual in-water mass before deciding.
• Ignoring installation dimensions: Not checking folded and deployed clearances can lead to interference with cockpit access or safety equipment.
• Underestimating electrical demands: Fitting an electric winch without checking battery and alternator capacity can produce disappointing performance or tripped circuits.
• Failing to reinforce the transom: Bolting into thin laminate without backing plates can damage the hull and create unsafe load points.
• Choosing excess complexity: Adding powered pivots or remote controls for infrequent use increases maintenance burden with little day‑to‑day benefit.

Before buying — a practical checklist

• Identify the tender’s fully loaded weight (engine, fuel, kit, occupants as appropriate).
• Measure available transom mounting area, folded and deployed clearances, and stern beam constraints.
• Confirm the structural backing and whether reinforcement or professional installation is needed.
• Decide whether manual, assisted or fully powered lifting suits your crew and usage pattern.
• Check electrical supply capacity and wiring routes for powered options.
• Consider access for routine inspection and emergency manual recovery.
• Ask suppliers about spare parts, local service networks and what is included in the kit (slings, cradles, fasteners).

Prioritise choices that match how you use the boat: choose simplicity and removability for occasional use and light tenders; favour robust, securely mounted and serviceable systems for frequent use, heavier tenders or offshore cruising. A well-chosen davit system reduces the daily friction of getting ashore, improves safety around the stern and protects the tender while under way — but only when it is correctly matched to both tender and boat and properly installed.
