Aspen C90 Operating Checklists
This Quick Reference checklist is a condensed checklist. It assumes that the operator is experienced
and competent in the safe operation of a power boat of this size, is knowledgeable of boating rules and
regulations, and has read the more detailed Aspen operating notes and the Aspen Owner’s Manual.
These notes do not attempt to anticipate every situation or occasion that may arise, and are not a
substitute for reading the Owner’s Manuals and other informational materials which are located on
the boat, or for exercising reasonable care and good judgment in the handling and operation of the
boat.
