Yes, I am putting all my boats on 1/8″ plywood bases, and my torpedo markers on posterboard bases as well. First, this cuts down on people handling the models directly, and it also makes movement and turning easier to do. I measure movement from the rear of the base (not the front of the model, as in the rules) and then just use that rear corner as the swing point for the turn. I put my torpedo markers on 10mm x 30mm posterboard bases as having a straight base edge to work with makes it easier to ensure the torps move straight ahead when they move.
My Vospers and US PTs are on 1 5/8″ by 4″ bases; my E-boats are 1 5/8″ x 5 1/4″, and my R-boats and Fairmiles will be on 1 5/8″ x 5 1/2″ bases. I try to leave about 1/2″ all around the model for wave effects and standardize as much as possible. As I move on to larger models the bases sizes will increase as well.
