Both the Nautica LC 17 2011 and the Nautica RIB 16 Deluxe 2011 are rigid inflatable designs, both built in fibreglass, so 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?
The power gap is worth calling out. Rated to 115 hp, the Nautica LC 17 2011 has a 25-hp advantage over the Nautica RIB 16 Deluxe 2011's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Nautica LC 17 2011 carries 48 gallons versus 30 gallons in the Nautica RIB 16 Deluxe 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 10 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the Nautica LC 17 2011 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Nautica RIB 16 Deluxe 2011 with its 90-hp rating is the more economical daily driver.
