Both the Voyager Marine 1570 BSC Bass 2009 and the Voyager Marine Series 4700 - 1247 2009 are flat-bottom designs, both built in aluminium, so 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 1570 BSC Bass 2009 at 15,0 ft versus Voyager Marine Series 4700 - 1247 2009 at 12,0 ft. Weight tells a clearer story for trailering families: the Voyager Marine 1570 BSC Bass 2009 tips the scales at 590 lbs - 500 lbs more than the Voyager Marine Series 4700 - 1247 2009 at 90 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 50 hp, the Voyager Marine 1570 BSC Bass 2009 has a 45-hp advantage over the Voyager Marine Series 4700 - 1247 2009's 5-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

Both boats are rated for 3 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Voyager Marine 1570 BSC Bass 2009 comes in at 12 lbs per hp versus 18 lbs per hp for the Voyager Marine Series 4700 - 1247 2009. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
