When two boats share the same hull type — in this case both the Arima Sea Pacer 21 2010 and the Arima SR Explorer 21 2011 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 — Arima Sea Pacer 21 2010 at 21,2 ft versus Arima SR Explorer 21 2011 at 21,2 ft. Weight tells a clearer story for trailering families: the Arima Sea Pacer 21 2010 tips the scales at 215 lbs — 190 lbs more than the Arima SR Explorer 21 2011 at 25 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 Arima SR Explorer 21 2011 tops out at 175 hp. Engine specs for the Arima Sea Pacer 21 2010 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 48 gal and 48 gal — so range won't be a tiebreaker here.

Both boats are rated for 6 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.
