That's exactly what many long-distance cruising folks end up doing. In most cases, the crew is carrying a cruising guide that offers detailed harbor chartlets and even some coastal chartlets as part of the guide, and these guides offer lat/long references
. (Examples are all the Imray & YM European guides, the Pavlidis guides for the Caribbean
, Bauhaus for Panama
and so forth). Once one confirms their accuracy and utility, buying
the few medium or large scale reprints to support passage
making and coastal hops is all one feels is needed for 'paper back-up'
Also, there are times when there is no guide or an older guide but without lat/long references
. When that's happened to us (e.g. when we visited Haiti
and the DR south coast), I just printed up screen-dumps from the NIMA electronic charts I had and then scotch-taped them together. Not very impressive looking, perhaps, but a reliable way to have a paper backup.
If a crew routinely hops around a given region - e.g. cruises the E Caribbean
chain or hops back 'n forth between the ICW
and the Bahamas
- it's easy to overlook how much sheer bulk (and expense) is involved in equipping a boat with both charts and guides for extended cruising
in one new region after the next. (And guides always seem to be preferred over charts because the regional detail, logistics info, etc. is so valuable). So for both these reasons - bulk & expense - it's very common for folks to rely on the guides to supplement that paper chart supply.
