Both the Blue Water Shadow 2009 and the Blue Water Sport Fisher 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 Shadow 2009 at 20,0 ft versus Blue Water Sport Fisher 2010 at 21,5 ft. Weight tells a clearer story for trailering families: the Blue Water Sport Fisher 2010 tips the scales at 3 650 lbs - 290 lbs less than the Blue Water Shadow 2009 at 3 360 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 Sport Fisher 2010 has a 50-hp advantage over the Blue Water Shadow 2009's 270-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 Sport Fisher 2010 carries 100 gallons versus 40 gallons in the Blue Water Shadow 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 8 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 Sport Fisher 2010 and its 320-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Blue Water Shadow 2009 with its 270-hp rating is the more economical daily driver.
