Why Choose a 12 Foot Alutender?

The Alutender series is renowned for its RIB-style (Rigid Inflatable Boat) design, which combines a solid aluminum hull with inflatable tubes that provide extra stability and buoyancy. The 12 foot Alutender is the smallest in the lineup, but it punches well above its weight in terms of performance, versatility, and ease of construction.

Perfect Size for Various Activities

Compact and Lightweight: At 12 feet, the boat is easy to tow, launch, and store, even for those who lack large trailers or storage spaces.
Capacity: Despite its size, the Alutender comfortably seats 3 to 4 people, making it suitable for family outings or small groups.
Multi-Purpose: Whether you want a fishing tender, a utility boat, or a simple leisure craft, this size provides ample flexibility.

Aluminum Durability and Maintenance Benefits

Aluminum boats like the 12 foot Alutender offer several advantages over traditional materials such as fiberglass or wood:

Corrosion Resistance: Properly treated aluminum resists rust and saltwater corrosion, extending the lifespan of your boat.
Lightweight Construction: Easier to transport and launch compared to heavier alternatives.
Low Maintenance: Unlike wood, aluminum does not rot or require frequent painting or varnishing.
Durability: Aluminum can withstand impacts and abrasions that would cause damage to other hull materials.
