About the HALCYON 23
Fin or triple keel models. Triple keel has cast Iron keel with steel plate fins. Fin keel draft: 3.5' Offered with a number of aux. power options.(gas or diesel) Nearly the same is the earlier CRYSTAL 23. Thanks to Halcyon 23 owner Rod Emberton for corrections and additional information.
Designed by Alan Buchanan and built by Offshore Yachts Ltd. (UK), the Halcyon 23 is a compact trailer-sailer with 1000 hulls built in 1967. Its lightweight 3100.0 lb displacement and 22.75 ft LOA define it as a nimble, easily transportable vessel rather than a heavy offshore cruiser.
- Best for:
- This boat suits coastal cruisers and trailer-sailers who prioritize ease of transport and storage over heavy-weather performance. It is ideal for single-handers or couples seeking a manageable, low-draft boat for protected waters and short passages.
- Bluewater capability:
- With a low D/L ratio of 212.66 and a capsize ratio of 2.06, the Halcyon 23 is not designed for serious bluewater cruising but is capable of short offshore passages in favorable conditions.
- Comparables:
- Comparable boats include the O'Day 23 and Pearson 23, which share similar dimensions and trailer-sailer roles from the late 1960s and 1970s. These vessels offer similar masthead sloop rigs and lightweight construction, making them direct competitors in the used market.
