Notes

The OFFSHORE/EMPIRE 40 was created as a replacement for the RHODES RELIANT in an effort to reduce costs of contruction and design royalties. Although from the same basic molds, the Offshore 40 has iron instead of lead ballast, as well some differences in other construction details. Sold as a sloop or yawl.
