This CMOR Card covers 2000 square miles of continuous, feature-rich bottom in Long, Block, Rhode Island Sound and Martha’s Vineyard. There are hundreds of shipwrecks, thousands of uncharted rocks, and countless ledges and mounds that hold the largest fish! The depths range from 1' to 385' in the deepest hole in the sound.
The coverage starts from Norwalk, CT on the NW corner to Eatons Neck on the SW corner and extends through the sound to east of Block Island.
The Long / Block Island Sound / Martha’s Vineyard CMOR card is the most complex and detailed chart ever created!

Package your card securely. DO NOT USE STANDARD MAIL. In several instances, sorting machines have torn envelopes and cards have been lost. We recommend a stiff mailer like a Priority Mail envelope, a padded envelope, or a small box.
Use a carrier that provides tracking and insurance. We strongly recommend insuring your card for replacement value.
Place your card in a sealed Ziploc-type bag inside the box or mailer.
