A tender is essentially a small boat used in conjunction with a larger vessel, serving as a versatile companion that facilitates transportation, safety, and convenience on the water. It acts as a bridge between the shore and the main boat, allowing passengers and supplies to move back and forth with ease. Beyond its functional role, a tender often embodies the spirit of adventure and exploration, enabling boaters to access shallow waters or secluded spots that the larger craft cannot reach.

In the following sections, we will delve deeper into the various types of tenders, their common uses, and why they are considered indispensable by many boat owners. Whether you’re interested in the practical benefits or the lifestyle elements tied to tenders, this guide will provide a clear and engaging overview to help you navigate this essential aspect of boating.

Types of Tenders and Their Uses

Boat tenders come in various types, each suited to specific purposes and vessel sizes. Choosing the right tender depends on factors such as the size of the main boat, typical water conditions, and intended use. Common types of tenders include:

  • Inflatable Tenders: Lightweight and compact, inflatable tenders are popular for their portability and ease of storage. They are often made from durable materials like Hypalon or PVC and can be easily deflated and packed away. Inflatable tenders are ideal for small to medium-sized boats and calm waters.
  • Rigid Tenders: Constructed from fiberglass, aluminum, or wood, rigid tenders offer more stability and durability. They typically provide better performance in rougher waters and can accommodate larger outboard engines. These are common for yachts and larger boats.
  • Rigid Inflatable Boats (RIBs): Combining features of both rigid and inflatable tenders, RIBs have a solid hull and inflatable tubes around the perimeter. This design provides excellent stability, buoyancy, and speed, making them suitable for a wide range of marine activities.
  • Dinghies: Traditionally small boats, often rowed or powered by a small outboard motor. Dinghies can be inflatable or rigid and are usually used for short trips to shore or as utility boats.
  • Pontoon Tenders: Featuring a flat deck supported by pontoons, these tenders offer spacious and stable platforms. They are less common but useful for leisure activities close to shore.

Each type of tender offers a unique combination of portability, durability, speed, and capacity, influencing the choice based on the owner’s needs.

Key Features to Consider When Selecting a Tender

Selecting an appropriate tender involves evaluating several critical features that impact functionality, safety, and convenience:

  • Size and Capacity: The tender should comfortably accommodate the number of passengers and cargo expected for typical trips, without compromising stability.
  • Weight: Lighter tenders are easier to launch, retrieve, and store aboard the main vessel, especially when using davits or cranes.
  • Material: Durability, maintenance requirements, and resistance to environmental factors vary between materials such as aluminum, fiberglass, and inflatable fabrics.
  • Propulsion: Options include oars, outboard motors, or electric propulsion. The choice affects speed, noise, fuel consumption, and environmental impact.
  • Storage and Stowage: Considerations include how and where the tender will be stored on the main boat—on deck, in a garage, or towed behind.
  • Safety Features: Stability, self-bailing design, grab rails, and non-slip surfaces enhance safety during use.
  • Cost: Budget constraints often influence the balance between features and quality.

Comparison of Common Tender Types

Type Material Weight Capacity Durability Storage Ease Typical Use
Inflatable Hypalon/PVC Light 2-8 persons Moderate High (deflatable) Calm waters, small boats
Rigid Fiberglass Fiberglass Moderate to Heavy 4-10 persons High Moderate Yachts, rougher waters
Rigid Inflatable Boat (RIB) Fiberglass hull with inflatable tubes Moderate 4-12 persons Very High Moderate Versatile, all conditions
Dinghy Wood, fiberglass, or inflatable Light to Moderate 2-6 persons Varies Varies Short trips, utility

Common Methods of Tender Storage and Deployment

Efficient storage and deployment of the tender are essential for convenience and safety on board. Popular methods include:

  • Davits: Mechanical arms attached to the boat’s stern or sides, allowing the tender to be hoisted out of the water and secured on deck or alongside. Davits facilitate quick launch and retrieval, especially for heavier rigid tenders.
  • Tender Garage: Some larger yachts feature dedicated storage compartments, or garages, below deck where the tender is stowed. This protects the tender from the elements and improves deck space usage.
  • Towing: Smaller inflatable or lightweight tenders can be towed behind the main vessel. While simple, this method exposes the tender to wear and may be less secure at higher speeds or in rough seas.
  • Deck Storage: Tenders may be stored on the main deck using cradles or chocks, secured with straps. This is common when davits or garages are not available but requires sufficient deck space.
  • Slide Systems: Hydraulic or manual slides allow tenders to be launched and recovered smoothly from the deck or stern.

Each storage and deployment method has advantages and limitations, depending on vessel size, tender type, and owner preferences.
