Reference Apps

Boater's Pocket Reference

Boater's Pocket Reference app icon

This app is like having a whole nautical almanac in your pocket. Need to know what a particular sound signal means, how to distinguish a ketch from a yawl, or what's the best way to set an anchor? All this, and more, is displayed in a simple, logical, and easy-to-understand format. Originally published as an 800-page book (the print version is still available), the Boater's Pocket Reference is an indispensable guide that makes interesting reading, even when you're not actually on the water. This is a great app for settling arguments at the marina after a day on the water. Available on the App Store. $4.99.

Boating Suite

Perfect for long-distance cruisers, liveaboards, and boaters who like to know how much fuel is in the tanks — to the very gallon — this is a logging app that turns your iPhone into a digital filing cabinet with built-in spreadsheets. Logs included are trip, fuel, maintenance, expenses, shopping, and to-do; reports can be organized by date and/or information included. Available on the App Store. $4.99 |


Dockwa app icon

This award-winning platform makes it possible to manage your next cruise from one integrated platform. With Dockwa, you can book slips, moorings, and dock space right from your phone or computer. No more reservations via email, phone or VHF radio! Dockwa is driven to simplify the exchange of information between captains and marinas. As an exclusive BoatUS benefit, members can digitally upload their membership within the Dockwa app or online at, allowing discounts at BoatUS participating marinas to be automatically applied prior to checkout. In addition, BoatUS members will have all booking fees waived when arranging dockage at a BoatUS participating marina, when a discount applies. Average savings are $20 per booking. If you do not see a marina on the platform that you like to visit, please let Dockwa know. The app and service is free for marinas, however they must elect to participate. Available on the App Store or Google Play. Free |

Knot Guide

Knot Guide app icon

Let's face it, everyone needs to know how to tie a few basic knots and, unlike grandpa, this app won't get grumpy when you have to practice over and over. With 95 knots, the clear pictures and illustrations make this a great learning resource. You'll find general boating knots such as the bowline and sheet bend plus there are decorative and fishing knots too. Don't know the bight from the working end? The app has that covered with a glossary so you can get to grips with knot terms. Available on the App Store. $1.99 |
