When two boats share the same hull type — in this case both the Trophy 1703 CC 2009 and the Trophy 183 CC 2009 are deep vee designs with fiberglass 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?

On paper these two are close siblings in the size department — Trophy 1703 CC 2009 at 17,0 ft versus Trophy 183 CC 2009 at 17,6 ft. Weight tells a clearer story for trailering families: the Trophy 1703 CC 2009 tips the scales at 1 873 lbs — 1 858 lbs more than the Trophy 183 CC 2009 at 15 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 115 hp, the Trophy 1703 CC 2009 has a 25-hp advantage over the Trophy 183 CC 2009'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 Trophy 1703 CC 2009 carries 37 gallons versus 33 gallons in the Trophy 183 CC 2009. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 5 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.

At this size, power-to-weight ratio matters more than outright horsepower. The Trophy 183 CC 2009 comes in at 0 lbs per hp versus 16 lbs per hp for the Trophy 1703 CC 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.
