When two boats share the same hull type — in this case both the Voyager Marine 1770 Bass Jon 2012 and the Voyager Marine All Welded Jons - SC 2012 are flat designs with aluminum 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 — Voyager Marine 1770 Bass Jon 2012 at 17,0 ft versus Voyager Marine All Welded Jons - SC 2012 at 19,9 ft. Weight tells a clearer story for trailering families: the Voyager Marine 1770 Bass Jon 2012 tips the scales at 645 lbs — 530 lbs more than the Voyager Marine All Welded Jons - SC 2012 at 115 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 135 hp, the Voyager Marine All Welded Jons - SC 2012 has a 75-hp advantage over the Voyager Marine 1770 Bass Jon 2012's 60-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 Voyager Marine All Welded Jons - SC 2012 is rated for 6 passengers, while the Voyager Marine 1770 Bass Jon 2012 caps at 4.

The Voyager Marine 1770 Bass Jon 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
