Same boat. Two personalities.
Both are 10 feet of virtually-unsinkable fun. The question is simple: do you want a tiller in your hand or a wheel?
Pick the TL if…
You want hands-on boating at its purest. The tiller puts every move right in your hand. You like an open deck, you might want electric power, and "grab and go" is your whole boating philosophy.
Pick the SC if…
You want to sit at a wheel, face forward, and captain your boat. The console gives it a big-boat feel, and the Mercury 15 package turns it into a proper little runabout.
