When two boats share the same hull type — in this case both the Palm Beach Pontoons 220 CastMaster SE 2011 and the Palm Beach Pontoons Echelon 260 2013 are pontoon 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?

Size is the most obvious dividing line here. The Palm Beach Pontoons Echelon 260 2013 measures 26,3 feet overall (2013), giving it roughly 4,3 additional feet of deck space compared to the Palm Beach Pontoons 220 CastMaster SE 2011 at 22,0 feet (2011). At 158 lbs and 232 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 175 hp, the Palm Beach Pontoons Echelon 260 2013 has a 60-hp advantage over the Palm Beach Pontoons 220 CastMaster SE 2011's 115-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 Palm Beach Pontoons Echelon 260 2013 is rated for 16 passengers, while the Palm Beach Pontoons 220 CastMaster SE 2011 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Palm Beach Pontoons Echelon 260 2013 could be the deciding factor.

Both are 2-tube and 2-tube pontoon designs respectively. Tube diameter and gauge affect stability and load capacity — more so than most buyers realize when comparing on paper.
