1987 Custom 13' Desilva F class Alky race boat

This 1987 Custom DeSilva F-class race boat carries on a storied lineage of high-performance wooden hulls built for competitive outboard racing. The 13-foot hull is powered by a single Mercury 70 hp engine and measures 4.83 feet across the beam. DeSilva boats, designed by Ralph and built by Bill DeSilva, earned their reputation through decades of national championship wins and speed records, becoming the standard for stock outboard racing from the 1930s onward. This example has been actively raced at Lake Winnipesaukee, New Hampshire.

The boat's construction uses marine plywood and Weldwood glue, techniques refined over the brand's evolution to create lightweight, fast hulls capable of handling serious competition speeds. The design reflects the refinements DeSilva introduced throughout the decades—from early 14-inch sides to the later 12-inch configuration that improved performance, along with continuous bottom design changes optimized for racing.

A spare rebuilt Mercury 78 engine is available as an additional component with this purchase.
