This has been a fun post to follow, but has anyone considered the phoenomenon Wind Gradient? It's the universal tendency of wind speed to increase with the height above water. Even on a windy day, the friction between air and water is such that the air immediately above the water's surface is barely moving. Within a foot or so of altitude the air speeds up dramatically, but it doesn't reach its maximum velocity until a good 30 feet or so above the water.
If you take this into account, you'll realize that there isn't that much pressure while the mast is in the water and as it raises, the wind's pressure will increase exponentially. I only mention this because it hasn't been brought up as a point here, but it is still a factor in the discussion and doesn't mean that I'd recommend pointing the mast into the wind. 45 degrees is still the way to go.
