I'm looking to add two new spring/seats, the helm seat and passenger seat. I found a spring, seems to be set up for boats, at least as advertised. About $550/each. I'm also looking to upgrade the seats from the original to the high grade pilot seats I see on the grady site. My question is has anyone don't this and may offer suggestions of how to have it done? I have not yet asked my GW dealer, Tri State, in Deale MD but I will. I boat on the Chesapeake out of Annapolis in the summer and New Smyrna Beach Florida in the winter. The main issue I have that I don't like of this wonderful boat (we've had it since '88) and it pounds my back, I'm 63 now and need the comfort. I am selling it eventually and going for the GW Dual Console, 33. But until I do this, in about 2 years, I want comfort. thanks for any comments. PJ
