This Appendix also includes a "Range. Speed, Endurance" Table that allows for the determination of these different parameters in determining possible cruise profiles. Copies of this table are available from the UNOLS Office

There are four line drawings of the deck layouts and machinery profile of the WESTERN FLYER. Copies of these drawings are available from the UNOLS office.
