Final answer:
Boats registered in another state may operate in Alaska for up to 90 consecutive days without needing to obtain an AK boat registration.
Step-by-step explanation:
Boats that are already registered in another state may operate in Alaska for up to 90 consecutive days without obtaining an AK boat registration. This allows for tourists or visitors who wish to use their vessels in Alaskan waters for temporary periods a certain flexibility. However, if the boat is to be used in Alaska for a period exceeding 90 days, proper registration within the state is required.
