When two boats share the same hull type — in this case both the Lowe R1455 2009 and the Lowe ST195 2009 are modified vee designs with aluminum 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 Lowe ST195 2009 measures 18,0 feet overall (2009), giving it roughly 4,0 additional feet of deck space compared to the Lowe R1455 2009 at 14,0 feet (2009). At 51 lbs and 106 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The power gap is worth calling out. Rated to 115 hp, the Lowe ST195 2009 has a 75-hp advantage over the Lowe R1455 2009's 40-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 Lowe ST195 2009 is rated for 5 passengers, while the Lowe R1455 2009 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Lowe ST195 2009 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The Lowe ST195 2009 comes in at 1 lbs per hp versus 1 lbs per hp for the Lowe R1455 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.
Bottom line: Choose the Lowe ST195 2009 if your priority is putting more people on the water — it handles 5 passengers and at 18,0 ft it has the deck room to back that rating up comfortably. The Lowe R1455 2009 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
