When two boats share the same hull type — in this case both the Voyager Marine 1770 Bass 2010 and the Voyager Marine 2070SC 2010 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 2010 at 17,0 ft versus Voyager Marine 2070SC 2010 at 19,9 ft. Weight tells a clearer story for trailering families: the Voyager Marine 1770 Bass 2010 tips the scales at 645 lbs — 530 lbs more than the Voyager Marine 2070SC 2010 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 2070SC 2010 has a 75-hp advantage over the Voyager Marine 1770 Bass 2010'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 2070SC 2010 is rated for 6 passengers, while the Voyager Marine 1770 Bass 2010 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Voyager Marine 2070SC 2010 could be the deciding factor.
Bottom line: Choose the Voyager Marine 2070SC 2010 if your priority is putting more people on the water — it handles 6 passengers and at 19,9 ft it has the deck room to back that rating up comfortably. The Voyager Marine 1770 Bass 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
