Lindblatt is very famous,,,and expensive for such high quality,,,i checked today ,5 march 2007, and the 12 day from near Seattle up the Inside Passage is per person double from $6890-8560,,, or $10330 for a single cabin. They take 62 guests in 31 outside cabins on their( 2) small ship(s), and it does not say how old these ships are or any pertinent ships log history. You can ask. Very reputable company that my folks have used.
AdventureSmith's yacht the Catalyst II is 19 days from near Seattle to Juneau all up and around the Inside Passage for less than about $6400. And that is with a private single cabin! On about a 12 cabin small yacht that use to be the official research vessel for the Univ. of Wa. Am sooo looking forward to this first cruise up the Inside !! AdventureSmithExplorations ,that was featured in a recent National Geographic magazine article on a similar NW trip, phone number is 800.728.2875 and ask for Todd. Please tell him 'dg' sent you , and i may get a beer out of this,,,
Happy trails !
