A tender is not just a “small service boat”: it is the gateway to the sea and an essential tool for comfort and safety on board. Choosing the right tender depends on many factors: hull type, material, weight, load capacity, propulsion, and intended use.

1. Types of Tenders

Rigid Hull (RIB – Rigid Inflatable Boat)

RIBs combine the strength of a rigid hull with the stability of inflatable tubes.Advantages:

  • Greater safety and stability, even in choppy waters.

  • Easier launching and transport due to the rigid hull.

  • Better handling compared to traditional inflatable tenders.

Disadvantages:

  • Heavier weight: requires more space on board and often a crane or davit for lifting.

  • Higher cost than standard inflatable tenders.

Inflatable Tender

Inflatable tenders are lightweight, compact, and easy to handle.Advantages:

  • Minimal storage space needed.

  • Light weight: can be handled manually.

  • More affordable.

Disadvantages:

  • Less stable in rough waters.

  • Care needed to avoid punctures or valve wear.

2. Safety Onboard

Safety is a top priority. Key points include:

  • Stability: tubes should be wide enough to resist waves and side-to-side movement.

  • Load capacity: never exceed the manufacturer’s limit.

  • Essential equipment: life jackets, bilge pumps, ropes, and a small anchor.

  • Rigid hull: offers better protection for the hull and engine in case of impact with submerged objects.

3. Weight and Handling

Weight affects transport, storage, and maneuverability:

  • Small inflatables can be launched by hand.

  • Larger RIBs often require a davit or crane.

  • Consider total weight including fuel, passengers, and equipment.

4. Propulsion

Electric Engines

  • Ideal for short distances, marinas, or low-emission zones.

  • Quiet, easy to use, and low maintenance.

  • Limitation: limited range and lower power than combustion engines.

Gasoline Engines

  • More powerful and suitable for longer distances and open waters.

  • Greater range and speed.

  • Requires more maintenance, fuel storage, and compliance with environmental regulations.

5. Additional Recommendations

  • Ropes and anchors: always carry extra lines and a lightweight anchor for safety.

  • Tube protection: avoid friction against hard surfaces and cover tubes when not in use.

  • Engine maintenance: regularly check oil levels, filters, and the propeller to prevent breakdowns.

Conclusion

Choosing the right tender involves considering usage, safety, weight, and propulsion. RIBs offer superior performance and safety, while inflatables provide lightness and convenience. Electric engines are suitable for calm, short trips, while gasoline engines provide more power and autonomy.

A well-chosen tender enhances comfort and safety, becoming an indispensable companion for every boat owner.
