Per VINdown's modeling, the South Bay 25 Sport SL9 DC retains an estimated 60% of its value after five years, ranking #4763 of 5915 boats we track. That trails the 62% five-year average for Pontoon in its class by 2 points, so it depreciates faster than most rivals.
Most of the loss lands early: the South Bay 25 Sport SL9 DC sheds about 20% of its value in year one alone. From roughly $147,513 it falls to around $88,212 by year five — a five-year loss near $59,301, about $32.49 a day in depreciation.
Because the steepest drop hits around year 2, a lightly-used South Bay 25 Sport SL9 DC bought at 2 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
