The Blue Wave 1900 STL 2011 vs Blue Wave Multi-Species MS-52 2005 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — Blue Wave 1900 STL 2011 at 19,0 ft versus Blue Wave Multi-Species MS-52 2005 at 17,0 ft. Weight tells a clearer story for trailering families: the Blue Wave 1900 STL 2011 tips the scales at 1 395 lbs — 400 lbs more than the Blue Wave Multi-Species MS-52 2005 at 995 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 150 hp, the Blue Wave 1900 STL 2011 has a 35-hp advantage over the Blue Wave Multi-Species MS-52 2005's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Blue Wave 1900 STL 2011 is rated for 7 passengers, while the Blue Wave Multi-Species MS-52 2005 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Blue Wave 1900 STL 2011 could be the deciding factor.
Bottom line: Choose the Blue Wave 1900 STL 2011 if your priority is putting more people on the water — it handles 7 passengers and at 19,0 ft it has the deck room to back that rating up comfortably. The Blue Wave Multi-Species MS-52 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
