D&D 5E – Nautical Adventures – Version 2

Revised rules for conducting a seafaring campaign in D&D. Including rules for Ship-to-Ship Combat.

You can download a free copy here:

This is a major update to my earlier Nautical Adventures supplement. I have changed form a Ship Record Sheet to the Ship Stat Block format as presented in the “Ghost of Saltmarsh” book under its “Of Ships and The Sea” appendix and have streamlined the special officer actions. This has made running ship to ship combat much faster and easier to play.
Everything here is fully comparable with “Ghost of Saltmarsh”. I highly recommend its “TRAVEL AT SEA”, “OCEAN ENVIRONS”, “ENCOUNTERS AT SEA”, “RANDOM SHIPS”, “MYSTERIOUS ISLANDS”, and “UNDERWATER LOCATIONS” sections for use in your nautical adventures.

    As usual I appreciate your efforts and willingness to share your work. Another great contribution Thank you. If you accept a suggestion I would revise the draft of ships. In my opinion they are on the low side especially if we take in account the possible weight of the crew and cargo. May be insted of feet could be yards. The Draft of the barge and raft leave me a little bit puzzled as they shoul be the example of a very low draft.

    Best wishes

      I agree. I can’t now remember where I originally got these numbers, but they have always seamed off to me as well. Can you point me to a reliable web site where I can find more realistic numbers, or perhaps some way to calculate the draft of wooden ships. I must admit complete ignorance on this topis.
      Thank you for your input. I will definitely reevaluate these numbers before I post the next update.
      If there is anyone reading this that can provide me with more accurate draft depths for these ships, please share.

        Hello Ronny, thank you for the kind answer, i am on the same boat as you, no knowledge. I have done a search on crossections images for sail boats and based on that i would propose that the draft could be like 1/3 of the boat’s hull for simple designs an 1/2, again of the hull, for models that have big fore and/or aft castles. I think that the ship’s plans you inserted at the end of your document somewhat confirm this ratio. Now based on the number of of the decks and their simulated height some new numbers can rougly come out. I hope i somewhat contributed.
