Both the Blue Water Magnum 2009 and the Blue Water Mirage 2010 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 Magnum 2009 at 19,0 ft versus Blue Water Mirage 2010 at 20,3 ft. Weight tells a clearer story for trailering families: the Blue Water Magnum 2009 tips the scales at 2 860 lbs - 360 lbs more than the Blue Water Mirage 2010 at 2 500 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 2010 has a 95-hp advantage over the Blue Water Magnum 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 Magnum 2009 carries 40 gallons versus 30 gallons in the Blue Water Mirage 2010. 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: Performance buyers should lean toward the Blue Water Mirage 2010 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Blue Water Magnum 2009 with its 225-hp rating is the more economical daily driver.
