BambooBar: Patrick O'Brian's Aubrey/Maturin series. The nautical theme is purely coincidental; they would keep you happy whatever activity you were engaged in.
Chrístõ: Patrick O'Brian's fine literary style would send a bone-weary solo sailor to sleep before they’d read a single paragraph. Much better would be the modern James Bond pastiches by Ian Fleming, Kingsley Amis, Christopher Wood, John Gardner, Raymond Benson, Sebastian Faulks, Jeffery Deaver, William Boyd, Anthony Horowitz, Charlie Higson, Steve Cole, etc. Take your pick!
