Suppose you have a satellite phone and excellent GPS— is it reasonable to avoid large bad storms and big ships in a sailboat? Let’s say you are pretty good at sailing. Would you need something bigger than 20’ to confidently avoid danger beyond your keel dappling around on the open ocean. (and you can provision and stay out of port for a month no problem.) No time tables but several places you want to get to eventually.
(it seems possible to me but ima harbor and sound baby)

@futurebird with AIS it is somewhat easier to avoid big ships (and oil rigs and wind farms), even in tight channels.
@th @futurebird Now available in waterproof, floating, handheld, too. https://www.landfallnavigation.com/icom-vhf-marine-transceiver-with-dsc-and-ais-m49d.html . AIS is part of DSC (digital selective calling) which is built on top of marine VHF, so you can point at a triangle and call them. No marine charts (with those shipping lanes) on this model tho.
