I managed to pick up 6 lighthouses on my cruise to Alaska:

Sentinel Island, AK
Point Retreat, AK
Addenbroke Island, BC
Brockton Point, BC
Prospect Point, BC
Triple Island, BC

Its amazing how many lighthouses were on our course and I managed to miss most of them. Most were passed while I was sleeping. The GPS didn't arrive until after we left, but the ship had a channel that showed the coordinates as well as course to date. The photos were all uploaded to
Lighthouse Joe\'s .
