The Many Types Of Boats That Have Dinghies

A dinghy is a small boat that is often carried or towed by a larger vessel and used as a tender for transfers from larger boats. Dinghies are usually rowed with oars, sailed with a removable mast and boom, or powered by a low-horsepower outboard motor. They are typically under 15 feet long and commonly around eight feet. Dinghies are used for a variety of purposes, including transportation to and from shore, fishing, snorkelling, and diving. When choosing a dinghy, it is important to consider factors such as the number of people who will use it, the frequency of use, the type of water sports activities it will be used for, and the available storage space on the larger vessel. Dinghies can be made of various materials, including wood, fibreglass, rotomolded plastic, and inflatable tubes constructed of PVC or Hypalon. They can also have different types of floors, such as slatted, inflatable, or rigid.

Dinghy storage

Dinghies are a type of small boat, often used as a tender for a larger vessel. They are usually rowboats or have an outboard motor, and some are even rigged for sailing. Dinghies are typically under 15 feet long, with an upper size limit of 20 feet in length.

When it comes to dinghy storage, there are several options to consider:

Davits

Davits are permanently installed at the stern of the boat and are used to store, deploy, and retrieve the dinghy from the water. This is a good option for dinghies that are too heavy to manually lift, but it can be risky when sailing through heavy seas as the dinghy can flood and damage the stern or davits.

On-Deck Storage

Some people choose to tie the dinghy upside down at the bow, stern, or side of the boat. This requires sufficient unused space on the deck and ensures that the dinghy does not interfere with any important pathways.

Swim-Step

Boats with an elevated swim-step can accommodate a dinghy at the stern, as long as it is elevated enough. The dinghy should be tied aerodynamically and tilted to prevent it from filling with water.

Locker Storage

Inflatable dinghies can be deflated and stored in lockers or lazarettes. They are easily deployed and retrieved by hand, making them a convenient option.

Towing

For nearshore journeys in calm conditions, the dinghy can be towed behind the boat. However, high speeds and choppy seas can cause the dinghy to flip, so caution is necessary.

When storing a dinghy, it is important to consider the size and type of dinghy, as well as the available space on the boat. Additionally, ensuring easy access for storage and use, while not reducing drag or restricting access to important areas, is crucial.

Inflatable dinghies should be stored in a clean, dry place, protected from major temperature variations and other damaging factors. The fabric of the buoyancy tube is delicate and can be easily damaged by certain cleaning products. It is recommended to use specific cleaning products designed for inflatable boats.

Dinghy carrying capacity

The weight-carrying capacity of a dinghy is determined by its size. Larger dinghies will generally have a higher weight capacity than smaller ones. The dinghy's weight capacity can be found on a capacity plate, typically placed at the helm or the boat's stern. This plate provides critical boat parameters such as maximum speed, maximum capacity, engine horsepower, and technical details.

If a capacity plate is not available, the maximum weight can be calculated by multiplying the length by the boat's weight and dividing it by 15. This will give a rough estimate of the number of people and the total weight the boat can carry. For example, a boat with dimensions of 18' x 6' can carry seven people with a combined weight of 150 lbs. It is important to note that this is an estimation and not the actual maximum load capacity.

The materials used in the construction of the dinghy also play a role in determining its carrying capacity. Rigid dinghies made of fiberglass or aluminum typically have lower carrying capacities than inflatable dinghies due to their heavier weight. Inflatable dinghies, on the other hand, are made of lightweight materials like PVC or CSE, which offer higher buoyancy and stability. However, they may have issues with air retention, as CSE tubes can lose up to 15% of their air within 24 hours, while PVC tubes lose less than 7%.

When considering dinghy carrying capacity, it is crucial to prioritize safety. Overloading a dinghy beyond its weight limit can lead to dangerous situations and put passengers at risk. Therefore, boat owners should carefully consider the number of passengers and the weight of cargo they plan to carry and choose a dinghy with a suitable carrying capacity.

Additionally, the intended use of the dinghy should be taken into account. If the dinghy will be used for long distances or rough conditions, a rigid dinghy or a Rigid Inflatable Boat (RIB) may be more suitable due to their stability and durability. Inflatable dinghies, on the other hand, are ideal for casual rides and offer the advantage of being lightweight and easy to inflate and deflate.

Dinghy maintenance

Inflatable Dinghy Maintenance

Inflatable dinghies are prone to leaks, so regular inspections are necessary to spot any issues before they become bigger problems. Check the fabric for any signs of wear and tear, and pay close attention to seams, cones, and valves as leaks often appear near labels or fittings. If you find any leaks, a professional repair is usually best. To prevent leaks, apply a UV treatment to your tubes once a month and clean the boat regularly. Avoid using products like 3M 5200, silicone, Flex Seal, roofing tar, or house paint on your dinghy.

Wooden Dinghy Maintenance

Wooden dinghies need to be varnished periodically.

Fibreglass Dinghy Maintenance

Fibreglass dinghies need to be polished and waxed regularly. They are also more susceptible to minor damage to the gelcoat finish, so it's important to repair any damage as soon as possible to prevent water from seeping into the laminate. Sand down the damaged area and apply gelcoat and hardener according to the manufacturer's instructions. If the damage has cut through the laminate, seek professional repair.

Rotomoulded Plastic Dinghy Maintenance

Rotomoulded plastic dinghies are durable and can usually withstand hard knocks, sustaining only minor scratches.

General Dinghy Maintenance

Regardless of the type of dinghy you have, it's important to regularly check the tightness of screws, bolts, and fittings, especially at the transom. Inspect ropes and wires for any signs of wear and tear and replace them if necessary. If you have a sailing dinghy, check the shrouds and forestay for any broken wires. Keep your dinghy clean and consider using a cover to protect it from the elements when it's not in use. Finally, make sure to store your dinghy properly to minimise the need for repairs.

Dinghy materials

Dinghies can be constructed from a variety of materials, with the most common being rigid or inflatable. Rigid dinghies are typically made from wood, fibreglass, aluminium, or marine plywood. Inflatable dinghies are usually made from synthetic materials such as PVC, Hypalon, or neoprene.

Rigid Dinghies

Wooden dinghies are constructed using either traditional or modern techniques and offer a classic look. Fibreglass dinghies are known for their low maintenance, while aluminium dinghies are lightweight and durable. Marine plywood is a lightweight alternative to wood that is treated with a UV-resistant varnish.

Inflatable Dinghies

Inflatable dinghies are made from coated materials, either synthetic rubber or plastic polymers. Synthetic rubber options include Hypalon and neoprene, which are known for their durability and resistance to UV light, chemicals, and extreme temperatures. PVC is a common plastic polymer option that is affordable, lightweight, and easy to clean.

Rigid Inflatable Boats (RIBs)

RIBs combine the benefits of both rigid and inflatable dinghies, offering stability and damage resistance. They are often constructed with a rigid hull made of aluminium or fibreglass, paired with inflatable tubes. RIBs provide excellent speed, handling, and stability, making them a popular choice for cruising sailors.

Dinghy safety

A dinghy is a small boat that is often carried or towed by a larger vessel and used as a tender. Dinghies are usually rowboats or have an outboard motor, and some are rigged for sailing. They are typically under 15 feet long, with an upper size limit of 20 feet in length.

• Ensure you have a personal flotation device for everyone on board. All PFDs (lifejackets) must be a Coast Guard-approved type, and children under 13 must wear a correctly fitted PFD.
• Carry a white all-around light that is visible from all directions.
• If your maximum speed is over seven knots, you are required to have red and green navigation lights (nav lights) at night, paired with the white all-around light.
• Ensure you have a means of making an efficient sound, such as a whistle or an air horn.
• If your dinghy is engine-powered, carry a night visual distress signal, such as Orion handheld flares, if you are motoring between sunset and sunrise.
• Carry a bailer or bilge pump to remove unwanted water from the dinghy.
• Keep a handheld VHF/mobile phone in a waterproof case to stay connected and call for help if needed.
• Always have a dinghy repair kit on board to fix small punctures or tears.
• Keep a fire extinguisher on board if your dinghy has a permanent fuel tank.
• If you plan to go fishing, snorkelling, or diving from the dinghy, ensure you have the necessary safety equipment for those activities.

Dinghy Storage and Handling:

• Consider the storage options for your dinghy. Common options include davits (installed at the stern), on-deck (tied upside down), swim-step (kept at the stern), locker (for inflatable dinghies), or towed behind the boat.
• Choose a storage location that does not reduce drag, restrict access to important areas, or hinder easy access for storage and use.
• If you have a rigid dinghy, ensure you have sufficient space to tie it on the deck or at the back of the boat.
• Inflatable dinghies can be stored in lockers or lazarettes when deflated.
• Consider the carrying capacity of your dinghy. Choose a dinghy that can accommodate the number of people you plan to carry, along with any luggage or recreational gear.
• Be cautious when loading your dinghy beyond its capacity, especially in rough seas.
• If you are towing your dinghy, experiment with the length of the tow rope to find the smoothest pull.

Dinghy Operation:

• Always check your dinghy's inflation levels and ensure there is no water inside before use.
• Ensure the outboard motor is appropriately mounted and test both forward and reverse gears.
• When operating the dinghy alone, clip the emergency motor stop to your clothing. If you fall overboard, the motor will stop.
• Bring the dinghy upwind when returning to your boat for a more controlled approach.
• If there is any surf present, do not attempt to beach your dinghy.
• Use a dinghy anchor if there are large tide changes, waves, or swells present.
• Stay with the dinghy if it capsizes. Do not swim back to shore, as you will be easier to spot with the dinghy.
• Avoid repetitive capsizes as they can be physically draining.
• If someone falls overboard, alert emergency services, keep your eyes on the person in the water, and start your recovery manoeuvre.

Remember to always follow local and regional safety regulations and guidelines, and enjoy your dinghy adventures safely!
