This are excellent. I had been designing one of my own to represent a generic S.A.R. but switched to a Pilot Boat, which sometimes can be used for S.A.R., for close in stuff. You have a great collection going on here. Here's a pic of an S.A.RR./Pilot boat I was working on, but I floundered on the project, though it would not take much to finish it. I planned to have a substantially full interior for it.
