My '89 Brendella had the floor re-done & engine rebuilt. The observer seat is missing and we've been using a friggin Tommy Bahama beach chair in it's place. This has been going on far too long! I also could use some detailed pics of the seat construction, or links to a place I could have one built, or even a kit would be amazing. I'm in Yelm, WA on Lake Lawrence, any help would be appreciated. Glad to see you are still making progress with your boat and look forward to hearing about the finish.
