When two boats share the same hull type — in this case both the Avon Rover Inflatables Series 2009 and the Avon SE 400 dl 2009 are inflatable rigid designs with inflatable construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
Size is the most obvious dividing line here. The Avon SE 400 dl 2009 measures 13,4 feet overall (2009), giving it roughly 4,9 additional feet of deck space compared to the Avon Rover Inflatables Series 2009 at 8,5 feet (2009). Weight tells a clearer story for trailering families: the Avon SE 400 dl 2009 tips the scales at 641 lbs — 580 lbs less than the Avon Rover Inflatables Series 2009 at 61 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The power gap is worth calling out. Rated to 50 hp, the Avon SE 400 dl 2009 has a 45-hp advantage over the Avon Rover Inflatables Series 2009's 5-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Avon SE 400 dl 2009 is rated for 5 passengers, while the Avon Rover Inflatables Series 2009 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Avon SE 400 dl 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Avon Rover Inflatables Series 2009 comes in at 12 lbs per hp versus 13 lbs per hp for the Avon SE 400 dl 2009. The lower the ratio the more explosive the acceleration — meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
Top speed is rated at 44 mph for the Avon SE 400 dl 2009 and 12 mph for the Avon Rover Inflatables Series 2009.
Bottom line: Choose the Avon SE 400 dl 2009 if your priority is putting more people on the water — it handles 5 passengers and at 13,4 ft it has the deck room to back that rating up comfortably. The Avon Rover Inflatables Series 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
