When two boats share the same hull type — in this case both the Blue Water Mirage 2010 and the Blue Water Sport Fisher 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 — Blue Water Mirage 2010 at 20,3 ft versus Blue Water Sport Fisher 2009 at 21,0 ft. Weight tells a clearer story for trailering families: the Blue Water Sport Fisher 2009 tips the scales at 365 lbs — 340 lbs less than the Blue Water Mirage 2010 at 25 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.
Both boats share a closely matched power ceiling — 320 hp for the Blue Water Mirage 2010 and 320 hp for the Blue Water Sport Fisher 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 3 gal and 1 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Blue Water Sport Fisher 2009 is rated for 8 passengers, while the Blue Water Mirage 2010 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Blue Water Sport Fisher 2009 could be the deciding factor.
Bottom line: Choose the Blue Water Sport Fisher 2009 if your priority is putting more people on the water — it handles 8 passengers and at 21,0 ft it has the deck room to back that rating up comfortably. The Blue Water Mirage 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.
