OFFSHORE CHECKLIST
~ preparing for sea ~

by Niki Perryman & Jamie Morrison

You’ve just purchased a new boat, and are planning your first voyage offshore.  There’s always so much to organise when you’re preparing for sea, and that sneaky feeling that you’ve forgotten something important is ever-present.  Here’s a basic checklist we’ve put together for our yacht deliveries, to give the grey matter a helping hand.  You may want to add a few items specific to your own boat.  Good voyaging!
