When two boats share the same hull type — in this case both the Robalo R247 2010 and the Robalo R305 2008 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?

Size is the most obvious dividing line here. The Robalo R305 2008 measures 29,0 feet overall (2008), giving it roughly 5,0 additional feet of deck space compared to the Robalo R247 2010 at 24,0 feet (2010). At 5 lbs and 96 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 700 hp, the Robalo R305 2008 has a 300-hp advantage over the Robalo R247 2010's 400-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 R247 2010 carries 15 gallons versus 3 gallons in the Robalo R305 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Robalo R305 2008 is rated for 8 passengers, while the Robalo R247 2010 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Robalo R305 2008 could be the deciding factor.
