This is to the best of my knowledge the last, most up-to-date version of the mod.
Let me know if it does not work

Since the GOG release of SeaDogs, I've gotten many requests for the mods. Much easier to upload them to the cloud than resurrect my old site. You can find them here:

The last two versions of the mods are there: 

SD111ALL.exe (50MB) 

Version 1.11, released in May 2003, 29 mods total, 10K+ downloads. Pretty stable. 

SD112ALL.exe (100MB) 

Version 1.12, released in August 2004, 31 mods total (+ many improvements to the 29 mods from Ver 1.11), about 1K downloads. If too many of the big campaigns in this version are installed at the same time, the game can "overload" at around 40 hours and quests will stop updating (click the Help button on the Master Status Screen of the Installer for tips on which mods to combine to avoid this problem). 

P.S. One of the old mods, Orzel's "no-sailing-against-the-wind" mod, was hard-coded by him with a check for the original game CD. Email me at ghighnote@hotmail.com, and I'll send you back the single file that you need to copy into the game to get this one to work (this should preserve the spirit in which his mod was copy-protected). 

Enjoy your return to the Archipelago!
