Duckworth 18 Advantage Sport keeps an estimated 70% of its value after 5 years — #1912 of 5915 boats VINdown tracks. See its full depreciation curve, cost per day, and best model year to buy.
Per VINdown's modeling, the Duckworth 18 Advantage Sport retains an estimated 70% of its value after five years, ranking #1912 of 5915 boats we track. That is 3 points above the 66% five-year average for Bowrider in its class, so it holds value better than most rivals.
Most of the loss lands early: the Duckworth 18 Advantage Sport sheds about 10% of its value in year one alone. From roughly $33,108 it falls to around $23,043 by year five — a five-year loss near $10,065, about $5.52 a day in depreciation.
Because the steepest drop hits around year 2, a lightly-used Duckworth 18 Advantage Sport bought at 2 years old lets the first owner absorb the worst of the depreciation while the curve flattens — usually the value sweet spot.
