Explorer charts are definitely the best. This subject has been discussed umpteen times on this forum. Use the search function.
Check out O- charts https://o-charts.org/shop/en/oernc/4...ts-exumas.html
Navionics charts are not recommended. Actually dangerous in some instances.
S-63 vector charts. Not recommended in this case. Useless and a waste of money
, except for a few commercial
harbors. The have nowhere near the coverage required by cruisers.
For Windows nv-charts is another candidate. While these charts are decent for the Bahamas, they are not quite up to Explorers standard.
