Captains and Cannons: A Ship Combat Guide in D&D 5e


Captains and Cannons: a Guide to Ship Combat in Dungeons and Dragons 5th Edition.

This ruleset explains how to run a ship battle in your campaign. Whether you want to fight on lashed-together longships, blast enemies with the cannons of your carrack, or just ram rowboats, this ruleset has everything you need.

Designed to be scalable, flexible, fast, and easy to learn, Captains and Cannons is here to make your naval based campaign come true.


  • Easy to learn rules on how to run ship combat encounters
  • 13 sample ships to use and adapt for your own campaign
  • 6 sample combat encounters, each with their own plot hooks, unique ship, and captains.
  • 4 sample "environmental challenges," complex weather patterns modelled after the complex traps in Xanathar's Guide to Everything.
  • List of ship equipment to upgrade and customise your vessel to fit your way of playing.


Mister Tarrasque: "If you're looking for a simple, yet deep ruleset to run a naval campaign, you should get Captains and Cannons."

JVC Parry: "If you and your group are looking for a realistic way to simulate naval combat in your D&D game that adheres to the basic principles of D&D 5e combat then this is certainly the supplement for you! 4.5/5."

Non Zero Sum Games: "For the cost of a fast-food meal you can have a supplement that you will access time and time again. 4.6/5"

I love the rule book but I want to print it up for my players to have a copy of the rules we are using for the pirate campaign we are doing. Can you add a copy without the brown back ground (printer friendly)?

This was a timely find for me due to a pirate campaign im in but I noticed the catapult doesn't say how many weapon slots it takes?

Jeffrey, could you contact me at my email please? I have a question I'd like to ask you privately sir. Phenominal job with this. My current campaign draws heavily on maritime AND aviation encounters and this unifies my rules. Its actually really close to the homebrew system I haphazardly set up for my players. This is one of my top materials so I would like to interest you in something. Thanks for your time bud amd thanks for the 5 star book.

if you could explain how your navel combat is different than the others thats been released id love to hear about it. there was a review video posted but I cant watch it at this time but I was wondering since others have either done section combats as players control some part of the ship, or normal combat with more actions to take using the ship. Love to hear your take on combat and health and repairs.

Hey there, thanks for the interest.

The main way I would say mine is different is that it doesn't require any one person to take full control of the ship the way that most rules do. I add the Ship phase which is when ships are allowed to move, and this prevents a thing I often saw in other rulesets where players were forced to wait for everyone else to move before they could do their own thing. This makes combat much more dynamic, and easily integrated with regular combat.

In fact my big goal was to have these rules be intuitive and easily integrated with the core rules. Ship health works similar to creature health, they have what are essentially hit dice, and crew members can restore them with crew actions.

Rules Edition(s)
Original electronic
Scanned image
These products were created by scanning an original printed edition. Most older books are in scanned image format because original digital layout files never existed or were no longer available from the publisher.

For PDF download editions, each page has been run through Optical Character Recognition (OCR) software to attempt to decipher the printed text. The result of this OCR process is placed invisibly behind the picture of each scanned page, to allow for text searching. However, any text in a given book set on a graphical background or in handwritten fonts would most likely not be picked up by the OCR software, and is therefore not searchable. Also, a few larger books may be resampled to fit into the system, and may not have this searchable text background.

For printed books, we have performed high-resolution scans of an original hardcopy of the book. We essentially digitally re-master the book. Unfortunately, the resulting quality of these books is not as high. It's the problem of making a copy of a copy. The text is fine for reading, but illustration work starts to run dark, pixellating and/or losing shades of grey. Moiré patterns may develop in photos. We mark clearly which print titles come from scanned image books so that you can make an informed purchase decision about the quality of what you will receive.
Original electronic format
These ebooks were created from the original electronic layout files, and therefore are fully text searchable. Also, their file size tends to be smaller than scanned image books. Most newer books are in the original electronic format. Both download and print editions of such books should be high quality.
