Not so much about cruising 
per se, but Arthur Watts (see 
The Art of Arthur Watts for details), father of my friend Simon Watts, wrote one or two books and illustrated a number of others. Additionally, he wrote a few articles for 
The Yachting Monthly prior to World War I about cruising aboard small boats—particularly aboard his boat, 
Mave Rhoe. During that war, he was in command of both a 
Motor Launch (ML) and an ML flotilla during the 
St. George's Day Raid on Zeebrugge and the follow-up raid on Ostend. In a very true sense, it was my interest in Arthur Watts that started me down the general path of research into his contemporaries.
Here is a list of books and articles Arthur wrote or illustrated that I have in my collection (sorted by publication year). You may also read some of what Arthur wrote here.
