Quickutz die cuts SAILBOAT, CRAB, LOBSTER, ANCHOR. Die cuts are mated and modified with additional die cuts. Crabs have rolley eyes.
Paper - DCWV Nantucket stack. Anchor and chain is made from a gritty paper (didn't photograph too well).
LARGE blank blue area is for a custom message for each card. I think this design will look better after the messages are added (especially the bottom two).
