Being both an insomniac and addicted to a rowing machine, I love my podcasts and can recommend the website 59 degrees north (www.59-north.com/onthewind) as having some excellent sailing podcasts, and ones that are more directed towards offshore cruising.

One of interest is a two part interview with respected rigger Brion Toss, and specifically his opinion on the best place on the boom to mount a preventer, and thoughts on preventers vs boom brakes. This is covered in part 2 which can be found at 24.44 minutes into:
