Project: Chairs and seating

Seating, other than the dining area type, seems to be a real issue in boats. We have some pretty strict "wants" in this area of the interior construction. Every possible boat seat we have looked at doesn't match any of out criteria. It's hard to believe, but it's true!
Here's a brief rundown of all the problems with seating, and following that, how I solved them. (1) The pilot seat. A very important seat. We always hear about cruisers being kept at sea in stormy weather, only to be taunted by a sore back and shoulders because of an uncomfortable seat. Our "research" has been limited to comparing seats in a car, or seats in a community center. Any type of seat one finds in power boats, that we have sat in or seen, is comfortable for about an hour. After that it's the stand up/sit down routine for the duration. Even padded seats are brutal after short lengths of time. Our "new" car's comfort pales in comparison to our old car, a New Yorker. We can seat and drive across the country for 8-12 hours and feel fine once arriving. The newer car on the other hand becomes a "back-burner" after only 6 hours. Why?? It's all in the padding and support areas we figure. The New Yorker seat is so well arranged, a lot of research obviously went into it. Because the rest of the car was becoming unsafe, and it was on the way to the scrap yard, I thought " why not keep the seat, and use it in the boat??" Happily Gena concurred. So out it went, and into the boat! More on that below.
(2) The Desk chairs Normally, for a desk chair in a boat, one buys a boat seat that swivels, and mounts it to the floor at an appropriate distance. We have seen some nice ones that move forward on a slider 6" long to adjust distance from the desk. The problem with this is the seat is "sticking out" into the gangway, and is always in the way when not in use. As the gangway aft at Gena's desk is only 22", this is a major problem. A special swivel and modification to a standard ( and cheap! ) office chair will solve the problem there. At my desk there is more width, but same problem, especially if something large like a sail is being carried through there. In addition to this, the seat must have a second position because of my keyboard drawer. The seat needs to be back at least 10 more inched for that. An arm that retracts with 3 locking positions is the solution, albeit a complex thing, will allow for all of the above criteria. More on that below!
The Navigation table seat: This seat is particularly challenging. It is at the edge of the aft entry, and must completely fold away, out of the way. I thought of using a stool that snaps in place, but can be removed and stored on a bulkhead, or on a locker. This seems to inconvenient, so a flod-away is the way to go. There should also be a back on it or whoever is sitting in it could fall off backwards and down the steps aft to the floor below. Not good! The back will also be fold away. See below for the design and a cool little video on that.
The pilothouse seating: No boat would be complete without a couple of nice reclining lounge chairs! The original design called for a dining area type set of seats around a coffee table, but we thought that would only be uncomfortable like the ones around the table below. We have purchased a couple of nice recliners from Sears, and I have figured out a way to have them in there despite Genas request for large 2/3 floor area opening hatches.
More to come!
