True but they aren't claiming water line length (LWL) only overall length (LOA). Tends to be mainly yachts that commonly state both.
However the LOA stated for trailer boats does seem to vary wildly how they measure this. I.e. Whether outboard pods are included etc. There doesn't seem to be an accepted standard?

I just think there is so much more choice in "tinnies" these days. Sure there are some much nicer boats out there but I think they are still good value. Not many 18month old 7m hardtops with 30hrs on the Honda 150 that you can pick up for about 60k like I did with mine.
They are pretty light which has its pros and cons but they have there place. Not everyone has (or wants) to spend 100-150k on a 7m Ali boat. Not bagging the others -would love something slicker if I had the $ but pretty happy with mine.
