Tsunami / Sceptre helm seat question

[ScottM]

Alan,
Since it looks like no one knows the original width, you may want to measure from the inside edge of the gunwale to a point towards the center of the boat that you're comfortable with and use that as the max. seat width. If you had the storage boxes like in the newer Sceptres, it would be as easy as making sure the seats didn't extend beyond the boxes.
