South Bay 521F keeps an estimated 64% of its value after 5 years — #3340 of 5780 boats VINdown tracks. See the full curve and the best year to buy.
Per VINdown's modeling, the South Bay 521F retains an estimated 64% of its value after five years, ranking #3340 of 5780 boats we track. That is 2 points above the 62% five-year average for Pontoon in its class, so it holds value better than most rivals.
Most of the loss lands early: the South Bay 521F sheds about 7% of its value in year one alone. From roughly $30,520 it falls to around $19,502 by year five — a five-year loss near $11,018, about $6.04 a day in depreciation.
Because the steepest drop hits around year 4, a lightly-used South Bay 521F bought at 4 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
