The Sea Hunt BX 21 Pro 2009 vs Sea Hunt Navigator 19 2007 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 - Sea Hunt BX 21 Pro 2009 at 20,0 ft versus Sea Hunt Navigator 19 2007 at 19,0 ft. Weight tells a clearer story for trailering families: the Sea Hunt BX 21 Pro 2009 tips the scales at 2 050 lbs - 490 lbs more than the Sea Hunt Navigator 19 2007 at 1 560 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 200 hp, the Sea Hunt BX 21 Pro 2009 has a 50-hp advantage over the Sea Hunt Navigator 19 2007's 150-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 58 gal and 58 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sea Hunt BX 21 Pro 2009 is rated for 6 passengers, while the Sea Hunt Navigator 19 2007 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Hunt BX 21 Pro 2009 could be the deciding factor.
Bottom line: Choose the Sea Hunt BX 21 Pro 2009 if your priority is putting more people on the water - it handles 6 passengers and at 20,0 ft it has the deck room to back that rating up comfortably. The Sea Hunt Navigator 19 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
