Hey doug, I have done this trip before but I came up from Seldovia. The only bad part was around the Chugach islands. Some pretty big tides in the area. Try and go for a slack tide if you can. Especially between the mainland and Elizabeth island. I helped a friend bring a 36' Bayliner from Seldovia around this time of the year.
Good luck my friend.
If you can't repair it maybe it shouldn't be on the boat
