Yamaha 23 III
Description
The Yamaha 23 III (also referenced as Y-23 or Y-23 III in some markets, with a related Y-23 II variant) is a compact Japanese-built fiberglass sailboat, likely from the late 1980s to early 1990s era. It aligns with Yamaha's limited sailboat production period (primarily late 1970s–early 1980s for export models, with some domestic/Japanese-market continuation). These were typically affordable, quality-constructed cruisers or daysailers emphasizing solid build and practical use.
