For the stainless steel rub rail, I decided to use the 1/2" wide, half oval type since at the back of the boat, the edge is not wide enough for a wider strip. It also seemed like it would be a better look on a small boat. However, there doesnt seem to be any ready made end spears available, so I experimented with shaping and forming the end until I got what I wanted. So heres what I came up with: 
1) Cut strip to length by clamping strip in some wood blocks and then in a vice. Cutting with a saws-all with a metal cutting blade.
2) Grinding the end to a rounded shape on the bench grinder.
3) Filing the back side flat to remove grinding burrs and flatten edges.
4) 
Laying strip on vice with end hanging off about 
1/2" and forming (pounding away) with a ball peen hammer until underside was flat.

A spring loaded center punch was used to mark the hole start and avoid wandering. A hole was drilled and then a countersink reamer until the screw head fit.
For the leading end of the splash rail, I made a form to bend the rub strip to fit. Clamping to the form and gently bending the strip by hand the yield point could be felt. With a few gentle bends and being careful not to bend it at the screw holes did the trick. The splash rails took a good part of a day to do, but the result is quite nice, I think.
