You mentioned Bothy Flake, which is a great tobacco in my opinion. It's perfect for when I want the occasional latakia flavor but still want to enjoy my beloved VA tobacco at the forefront. Capstan Blue Flake and Salty Dogs are both great tobaccos. PS LNF has probably one of the best quality-to-cost ratios around, especially with a few years of age on it.
Although not marketed as a navy style tobacco, I think Wessex Gold Brick fits in this thread since it's a straight VA plug worthy of a long sea voyage. It's up there with Capstan in terms of quality but it's not always in stock.
