Yeah, I've messed witht he surprise simulator, and I have no desire for that level of complexity. OTOH, I want the physics, the outcomes, to be realistic. Soo I'm perfectly happy with a slide bar for the speed I'd like the ship to make given the direction I happen to be going. Heck, I'd be fine with an AI Sailing Master. "Mr. Allen, put us 1 cable length from her on the larboard tack" 2 hours later, there we'd be, the computer would do the math
