Rigid Inflatable Boat Tender – The Ultimate Guide

Why a RIB Tender is Essential for Larger Boats

The tender is often the unsung hero in yachting or commercial shipping. Beyond simple transportation, a well-made tender can handle supply runs, serve as a secondary rescue craft, or provide a quick jaunt to explore shallow bays. RIB tenders, in particular, solve many pain points by delivering:

• Stability in Chop: Inflatable tubes act like outriggers, minimizing roll and ensuring dry rides.
• Lightweight Handling: Launch and retrieve easily—especially crucial if you’re hoisting it aboard or using a davit system.
• Fuel Efficiency & Speed: The rigid hull planes swiftly and uses less fuel for similar distances compared to heavier, all-fiberglass alternatives.
• Space Efficiency: The compact design and inflatable tubes allow for simplified storage on deck or in a garage compartment.

Aluminum vs. Fiberglass Hulls for Tenders

Traditional tenders often rely on fiberglass hulls. However, the aluminum revolution—spearheaded by high-grade alloys like 5083—has redefined what’s possible in small craft:

• Weight Savings: Aluminum hulls are lighter, easing portability and saving deck crane capacity.
• Impact Tolerance: Aluminum can dent rather than crack, making it more forgiving during occasional bumps against docks or the main vessel.
• Corrosion Resistance: With proper coatings and anodes, 5083 aluminum shrugs off saltwater exposure and remains structurally sound for decades.
• Easier Planing & Speed: Less hull weight means quicker acceleration and improved fuel economy—great for short daily runs or extended explorations.

By combining an aluminum hull with modern design techniques, Novelli’s tenders exemplify how a RIB can drastically outlast traditional inflatable dinghies in harsh marine environments.

Foam-Filled Tubes: A Standout Feature

Many RIB tenders still feature air-filled tubes, but foam-filled technology continues to gain traction, especially in demanding conditions:

• Unparalleled Buoyancy: Foam retains its structure even if the outer tube is punctured, preventing deflation and related hazards.
• Reduced Noise & Vibration: Foam dampens water slap, delivering a quieter ride—vital for comfort-conscious yacht owners.
• Zero Inflation Maintenance: No need to check or top off tube pressure; focus on cleaning and checking for surface abrasions only.

Though foam-filling adds to initial costs, the reliability and minimal upkeep can be game-changing, especially if your tender sees frequent daily use.

Size & Capacity Considerations

Not all RIB tenders are created equal, and selecting the right size can significantly affect daily operations:

• Passenger Load: If you frequently ferry multiple guests, you’ll need extra seating or open deck space.
• Storage Constraints: Measure your yacht’s deck, swim platform, or tender garage thoroughly to ensure it accommodates your chosen tender’s length and beam.
• Weight Restrictions: Cranes or davit lifts often have capacity limits. A lighter aluminum RIB tender can be hoisted more easily without over-stressing the system.
• Intended Use: Day trips, diving, or water sports might require additional gear storage, dictating a larger, more robust design.

Novelli’s Approach to RIB Tender Design

Recognizing that a tender can be an owner’s first impression of a larger boat, Novelli invests in both aesthetics and engineering:

• AI-Optimized Hull: Our computational fluid dynamics (CFD) analyses refine each contour for smooth planing, minimal drag, and maximum stability.
• 5083 Aluminum Construction: Resistant to dents and corrosion, it’s the ideal foundation for a tender that sees daily use in salty or brackish waters.
• Foam-Filled Tubes: Eliminates deflation risks, and the quieter ride ensures discreet arrivals at marinas or anchorages.
• 25-Year Hull Warranty: Even though a tender might endure heavy use, we stand by our hulls for the long haul—reflecting confidence in every weld and plate.
• Customization Options: From console positioning to seat fabrics, each Novelli tender can match your yacht’s style or unique functional needs.

Performance & Propulsion

A RIB tender typically pairs with outboard engines. While horsepower requirements vary, even a small tender can reach respectable speeds:

• Compact Models (2.5–3.5m): Often equipped with 5–20 HP outboards—enough for short runs to shore.
• Mid-Size Tenders (4–5.5m): A 25–60 HP engine allows for planing speeds, hauling gear, and moderate water sports.
• Larger Tenders (6m+): May use 70–150 HP or more, turning them into versatile crafts for extended journeys or towing activities.

At Novelli, we guide owners in selecting or retrofitting outboards optimized for both the tender’s hull and the main vessel’s mission—ensuring you strike the right balance of speed, efficiency, and weight.

Handling & Stability

One of the greatest selling points for RIB tenders is how they handle in various sea conditions. This advantage emerges from:

• Inflatable Collar Buoyancy: The tubes maintain stability and reduce rolling, even with multiple people leaning on one side.
• Deep-V or Modified-V Hull Designs: Slices through chop, preventing bow slap and ensuring a smoother, drier ride.
• Foam-Filled Tubes (Novelli Feature): Further dampen impact noise and keep the boat stable if the outer tube is compromised.

These characteristics make RIB tenders safe for family members or guests who may be less experienced with small boats.

Deck Layout & Customizations

While basic tenders keep seating and storage minimal, owners can tailor the layout to specific needs:

• Console Type: Choose between a simple tiller-operated setup or a small center/side console for better steering control and instrumentation.
• Seating Configurations: Bench seats, jockey seats, or modular systems let you prioritize passenger comfort or cargo capacity.
• Storage Compartments: Integrated lockers for life jackets, anchor gear, or personal items keep the deck uncluttered.
• Flooring Material: Non-slip aluminum or synthetic decking for better traction in wet conditions.
• Style & Color: Match the tender’s color scheme to your main vessel for a cohesive, luxurious impression.

Novelli’s design philosophy allows for flexible modifications, from plush seats to minimalist, utility-focused solutions.

Tender Length (m)	Recommended Engine (HP)	Passenger Capacity	Common Uses
2.5–3.0	5–15	2–4	Short hops, light cargo
3.5–4.0	15–30	4–6	General tender duties
4.5–5.0	30–60	6–8	Longer trips, moderate cargo
5.5–6.0	60–100	8–10	Watersports, heavier loads

Maintenance & Care for RIB Tenders

Proper upkeep of a RIB tender ensures reliability, longevity, and a polished appearance:

• Rinsing & Cleaning: Salt, sand, or debris can degrade both tubes and metal surfaces. Rinse thoroughly after each outing.
• Hull Inspection: Regularly check aluminum welds or coatings for signs of wear, especially if the tender endures frequent beach landings.
• Tube Care: For foam-filled, monitor the external tube covering for scuffs or UV damage. Air-filled tubes need periodic pressure checks.
• Engine Servicing: Follow the outboard’s recommended oil changes, spark plug replacements, and flush the cooling system with freshwater.
• Storage & Covering: If left on a swim platform or in a tender garage, use a fitted cover to shield from UV and debris.

Tips for Choosing the Perfect Tender

Every boater’s scenario differs—large yachts need powerful, cargo-friendly tenders, while day cruisers may only require a basic shuttle. A few final pointers:

• Assess Main Vessel Limitations: Consider crane capacity, storage locker size, or deck space when deciding on length and weight.
• Define Primary Usage: Fishing, diving, guest transport, or watersports each influence layout and engine demands.
• Match Aesthetics & Quality: A tender is often the first impression for guests—opting for a well-finished RIB aligns with a premium yachting experience.
• Set a Realistic Budget: Factor in potential upgrades, electronics, or even a repower if you’re buying a secondhand RIB tender.
