Can install a cheap VHS with a Metz antennae on the rail until you have a chance to put an antennae on the masthead for better reception. But the handhelds are limited in range.
The boat looks great. First thing is to sail and then decide what else you might need.
As far as Chartplotters - beware of Garmins pricing strategy these days. Buy a pre-loaded Colorado or 478 unless you are ready to go ahead and install a big unit and then I think Raymarine is better. They don't have a handheld.
Twenty years from now you will be more disappointed by the things y%^&*.....oh never mind. 90% of the people on sailing forums already use that as their signature! I'm not a conformist.
