Best source for cruising guides?
It''s my impression that what makes a guide ''best'' is in the eye of the beholder. E.g. some love the C. Young SE USA guides; they love his folksy chatter, his constant (some would say ''relentless'') references to food and restaurants, and his smattering of historical anecdotes. Others find ''real'' cruising info in his guides to be slim while most of the content - for them - is irrelevant and unhelpful.
I''d suggest the answer will likely rest more with you than with what some of us think. Having said that, especially once you leave the USCG/CoE nav aids of the USA, highly reliable, scaled sketch charts or ''chartlets'' (e.g. the Pavlidis guides, which soon will be encompassing most of the Caribbean) are what might be considered a mandatory minimum in any guide''s content. Opinion still varies about whether waypoint info is ''good'' or can lead one astray (e.g. VanZant offers bountiful WPs, not one of which have I been disappointed by, while Pavlidis only offers offlying WPs and feels to offer more is irresponsible on his part). My preference is FOR waypoints, but then I develop alternative ways to verify their accuracy (cross-bearings or soundings, e.g.) when using them. So...lots of room for personal judgement, it seems to me.
