Bill, I would install a metal backing plate under the deck , so structurally I am not too concerned. It is that the tube is sleeved (allowing for height adjustment)and attachment points under the seat may combine to allow a degree of movement that concerns me. My seat now only has a slight curvature built in for adjusting to heel ,you may have the same seat. The chair I am looking at has side bolsters that mimics that somewhat. Since we are generally on auto pilot , I could swivel the seat seat towards windward and have a 15 degree recline,might be pretty comfortable while still be able to monitor gauges. My main concern is that it may look a bit big and movement,that would bother me.

Thanks,

Pat

Pat,

The concern I’d have about sitting in a typical pedestal seat is not rough seas, but rather heeling. There are many very comfortable helm seat built for high end motor yachts, but they all assume that the boat is basically flat. I have not yet seen a pedestal seat I’d want to sit in when heeled at 15 degrees.

The other issue around a pedestal is structural. The deck in that area might need strengthening to support a single point of attachment of a pedestal. Note for example, the way the nav station seat pedestal is built into the boat.
