US 21
Description
The US 21 (also known as the US Yachts US 21) is a lightweight, trailerable fractional sloop daysailer/weekender built by US Yachts / Bayliner (part of the Buccaneer/US Yachts family) in the early 1980s. It was developed as an affordable, fun performance-oriented pocket boat with a small cuddy cabin. Production was relatively short-lived; the design later evolved into the Triton 21 after Pearson acquired the tooling.

Sailrite does its best to publish accurate dimensions, but we often find it worthwhile to have our customers measure their boats carefully before we produce kits for them.
