Both the Blue Water Mirage 2011 and the Blue Water Sportsman 2009 are modified-V 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?
On paper these two are close siblings in the size department - Blue Water Mirage 2011 at 20,3 ft versus Blue Water Sportsman 2009 at 18,0 ft. Weight tells a clearer story for trailering families: the Blue Water Mirage 2011 tips the scales at 2 500 lbs - 150 lbs more than the Blue Water Sportsman 2009 at 2 350 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 320 hp, the Blue Water Mirage 2011 has a 95-hp advantage over the Blue Water Sportsman 2009's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Blue Water Mirage 2011 carries 30 gallons versus 25 gallons in the Blue Water Sportsman 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 7 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: The Blue Water Mirage 2011 at 20,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Blue Water Sportsman 2009 at 18,0 ft wins on trailering ease, likely lower purchase price, and simpler docking - a solid choice for a buyer who wants more boat for less money.
