Pitman and
Moody both collected stamps at points in their lives. I don't know if
Moody was still collecting as an adult - he was certainly keen as a child, and sent home interesting stamps to his family.
Blair, Lowe and Moody all dabbled in photography - Blair and Lowe were quite proficient in it, but again I think Moody's interest tapered off a bit.
Lowe enjoyed fishing and shooting his entire life, and I seem to recall
Lightoller had similar interests. Lowe also sketched and did the odd watercolour (perhaps not surprising, as the son of an accomplished artist).
Moody and
Lightoller were quite handy with woodworking tasks - there are one or two examples from Moody's childhood, for example a stamp box he made, and there's a wonderful photo of Lightoller on the
Oceanic exhibiting his boatbuilding skills - skills he later put to good use in his Twickenham boatshed. Lowe built at least one duckpunt in his life, and like Murdoch (and, I think, Lightoller) was quite handy with boatmodelling. Lowe had a workshop in later years that he used for bits of woodwork and similar tasks.
