Welcome back, its like riding a bike, you never forget.
The gear these days is better, both boards and sails, but in particular sails. Good second hand gear can be easily found. Boards if looked after and watertight are good for 5 or more years. Sails up to 3 or 4 years, monofilm gets brittle over time. Spend money on a carbon boom (good insurance against breakage - especially in the ocean) as well as at least 75% carbon RDM masts. The FSW board is a good choice. 92l will not float you, so you need to be a proficient water starter. The general rule for a floater is 20l above your body weight. Reasonable second hand board and 2 sails will set you back about $1200 to $1800, New mast, boom, harness lines, mast extension and base about $1600 to $2000 - less if you can find second hand. If you stick with constant curve designed sails and masts (eg Naish, North, Loft, Ka, Ezzy, Sailworks) you can mix and match. The following guide takes the mystery out of this vexing issue.
