It is a shame, but size seems to matter when in company with other boats. Even my SansP (which is a whopper compared to most of yours) seems to lose significance when on the pond. Perhaps you should wow with quantity when taking boats down? The total is bigger than the sum of its parts (or whatever the saying is)
Paint,, I think you are a man who uses what is convenient and/or to hand. I must say acrylics are very useable for small areas, easy clean-up and fast drying. A lot of people worry about durability but for the amount of time these things spend in the water this just cant be anything to worry about (obviously you do not have that worry!)
My larger models tend to get the household paint treatment…
