Nice looking model. The paint scheme and geometry resembles a scratch built model I started back in the 80's and only recently started to finish based on a 1986 Bayliner 3250 cabin cruiser. Covid has resurrected all those builds that were started and never finished.
Mine is not a true scale model, but it is about 20" long from the bow sprite to the swim platform, balsa construction and was designed from the cover photo and an article in a July 1986 issue of Power Boating Ontario.
After doing a "dryfit on parts", Christmas looks like a good time to finish this one off and maybe do build journals on the many models I have in my drydock (been a recruit for to long). Like yours it is powered with a 540 motor and uses a 32mm prop.
