Speed & Smarts is a bi-monthly newsletter packed with tips to improve your racing performance. It's written by winning AC tactician David Dellenbaugh, and each issue has 16 pages full of instructional advice on tactics, strategy, speed, boathandling and rules (plus there's no advertising!).
David Dellenbaugh, winning Americas Cup tactician, is the author of Speed & Smarts and Learn The Racing Rules.
Issue 139 is all about drills you can use in your next training session or pre-race warmup. It starts off with practice philosophy and then explains more than 30 exercises you can use for improving the skills of your team. The drills are broken into groups according to how many boats are in your training session (just yourself, 2 or 3+) with a focus on fun and an assumption that you'll be doing these drills without a coach or coachboat.
