When two boats share the same hull type — in this case both the Robalo R220 2011 and the Robalo R247 2010 are modified vee designs with fiberglass 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 — Robalo R220 2011 at 21,5 ft versus Robalo R247 2010 at 24,0 ft. Weight tells a clearer story for trailering families: the Robalo R220 2011 tips the scales at 397 lbs — 392 lbs more than the Robalo R247 2010 at 5 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 400 hp, the Robalo R247 2010 has a 150-hp advantage over the Robalo R220 2011's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Robalo R220 2011 carries 109 gallons versus 15 gallons in the Robalo R247 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 1 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.
