Ranger IV Basis of Design 7/18/2022

Ranger IV Basis of Design This document lists the key requirements, assumptions, and regulations that form the basis of the design for Ranger IV.

Overall Design Goals Ranger IV shall be designed to meet all missions performed by Isle Royale National Park (ISRO).

Ranger IV shall be designed to meet USCG, ABS, and other applicable regulations and safety standards.

The service life of Ranger IV shall be 50 years.

The ship shall be designed to ensure the safety and comfort (stability) of passengers. Ranger IV will typically not operate with passengers above Sea State 7 on the Beaufort Scale.

It is anticipated that Ranger IV will be constructed at a Great Lakes shipyard. All major equipment shall be able to be installed, maintained and recertified on the Great Lakes. It is the intent of the National Park Service for the Ranger IV to remain on the Great Lakes throughout the life of the vessel.

Propulsion, electric, lifesaving, and other major components must have service locations on the Great Lakes or within 10-hours’ drive of Houghton, MI within the United States.

Ranger IV Missions Ranger IV must meet a number of missions to support operations at Isle Royale National Park:

• Passenger ferry service for visitors, staff, and families to/from ISRO

• Cargo transport for supplies to/from ISRO, including power boats, hand-loaded boats, passenger baggage, refrigerated/frozen foods, non-perishable foods, general cargo, construction materials, and trash

• Fuel transport to ISRO, including diesel, propane, gasoline, and aviation gas

Operating Location and Season Typical operating season is mid-April through mid-October, approximately 45-50 total roundtrips per year.
