You'l be pleased to know that I have abandoned the idea of 'driving' my boat to Brighton now and shall be having it transported by road instead.
However, when I am down there I'll be needing some kind of Nav device I assume...so what would be a good one for coastal trips for an ambitious newbie (hope to go to Channel Isles/France at some point). I'd like it to be removable and non-hard wired if poss.
