This CMOR Mapping Chart: Long / Block Island Sound / Marta's Vineyard 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!

When a CMOR card is updated or expanded, we offer owners of the previous version the option to trade in their cards for the new version for $100. You can buy the updated version of your card here on our website.
If you purchased the previous version of your card within 60 days of the update, trade-in is free. Simply select the “Within the last 60 days” option below. You must provide your original order number to verify date of purchase. We’re open 9 a.m. to 5 p.m. Monday through Friday.
Please note customers are responsible for the cost of shipping labels to return CMOR cards for updates.
For South Florida customers, the easiest way to get an update is simply to bring your old card and your original order number into our retail location at 3311 S. Andrews Ave, Suite 11 Ft. Lauderdale FL.
Once you complete checkout, you will need to return your old card to CMOR.
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.
Include the order number from your update purchase on a piece of paper with the card. If possible, print and include your confirmation email.
