When two boats share the same hull type — in this case both the Trophy 1806 DC 2008 and the Trophy 2006 DC 2009 are modified 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 1806 DC 2008 at 18,0 ft versus Trophy 2006 DC 2009 at 20,5 ft. Weight tells a clearer story for trailering families: the Trophy 1806 DC 2008 tips the scales at 2 085 lbs — 1 840 lbs more than the Trophy 2006 DC 2009 at 245 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 200 hp, the Trophy 2006 DC 2009 has a 50-hp advantage over the Trophy 1806 DC 2008's 150-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 2006 DC 2009 carries 75 gallons versus 6 gallons in the Trophy 1806 DC 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Trophy 2006 DC 2009 is rated for 6 passengers, while the Trophy 1806 DC 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Trophy 2006 DC 2009 could be the deciding factor.
Bottom line: Choose the Trophy 2006 DC 2009 if your priority is putting more people on the water — it handles 6 passengers and at 20,5 ft it has the deck room to back that rating up comfortably. The Trophy 1806 DC 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
