6 Metre RIB Boats FAQs
What is the best 6 metre RIB boat in Australia?
The best 6 metre RIB boat in Australia depends on how you plan to use it. A high-quality 6 metre rigid inflatable boat should offer a comfortable amount of seating for at least 8 passengers, a stable deep-V hull, high-quality finishes and a warranty of at least 5 years. Models such as the Grand G580, D600 and G680 are designed for different boating styles, from family cruising to performance and premium entertaining.
Is a 6 metre rigid inflatable boat suitable for offshore boating?
Yes, a well-designed 6 metre rigid inflatable boat can be suitable for offshore boating in appropriate conditions. The combination of a fibreglass deep-V hull and inflatable tubes provides excellent stability, buoyancy and ride comfort, making 6 metre RIBs popular for coastal and offshore use in Australia. The depth of the v-shaped hull will determine just how comfortable and dry the ride is, so be sure to speak to your RIB boat expert for more information on this.
What are the advantages of a 6 metre RIB compared to a fibreglass boat?
A 6 metre RIB offers greater stability at rest, improved safety from inflatable tubes, and a softer ride in choppy conditions compared to many traditional fibreglass boats. Rigid inflatable boats are also typically lighter, easier to handle, and more forgiving when docking, making them ideal for families and experienced boaters alike.
How many people can a 6 metre RIB boat carry?
Most 6 metre RIB boats are rated to carry 10 – 12 people, however depending on the model and layout usually comfortably carry 8 – 10 people. Seating configuration, tube diameter and deck space all influence capacity, so it’s important to choose a 6 metre rigid inflatable boat that suits how you plan to use it.
Are 6 metre RIB boats easy to tow and store?
Yes, one of the key benefits of a 6 metre RIB is ease of ownership. Most 6 metre rigid inflatable boats can be trailered behind a suitable family vehicle without having to deflate the tube. They can also easily be stored at home, and some models can even fit inside a garage where overall headroom height is limited.
What engine size is best for a 6 metre rigid inflatable boat?
The ideal engine size for a 6 metre rigid inflatable boat typically ranges from 115hp to 200hp, depending on hull design, load and intended use. A deeper v hull will perform better with a higher horsepower, while a boat with less deadrise may be overpowered with a high horsepower. Higher horsepower suits water sports and offshore use, while lower horsepower can be ideal for cruising and family boating.
How long does a quality 6 metre RIB boat last?
A high-quality 6 metre RIB built with premium materials and properly maintained can last many years – often up to and exceeding twenty years. European-built rigid inflatable boats with advanced tube fabrics and quality fibreglass construction are known for their durability, longevity and strong resale value.
