Just to add to Ray's post, I have a simple test : Will it fit on the back seat of the car ? (although it's an estate car, I'm sure the rest of the rear space will be full of marine 'clutter'.
Getting to the sailing area maybe OK, but you may need assistance if your large transport fails you….just a thought.
As a guide my Pilot Cutter hull is around 42" loa and I'm starting to struggle getting it down from a 6 foot high shelf and it's only part-built (cries of "Weakling" !).
However, if you're young and fit, then happy modelling, well, happy modelling anyway..,
