Other traits of my foremast included some difficulty in picking up a mooring single handed. It was hard to see from the cockpit and when you did get close, a gust could easily push the bow away from target. I generally approach from the lee and hoisting the mizzen could possibly mitigate that effect to some extent, but I haven't tried yet. If you are planning on going off-shore, this won't be an issue.
A positive aspect of raked foremast was the ability to sail by the lee. Often on a broad reach, I could keep the foresail on opposite side of main and mizzen. It is interesting and because it is higher up, the sail catches the wind better than on the lees side. All sails are easy to trim and provided the boom is high enough, you have great visibility. I found the foresail can obstruct visibility if on the lee side and depending on the angle, with my main mast positioned quite far forward I often couldn't even see the foresail except by looking up the lee side. It means more stooping and generally upper body movement. It was good for my waistline!
Regarding the MOB situation, as a single-handed skipper I hope never to be in that situation, but looking back to the time I helped out with rescue boats at regattas, we generally approached from the lee and dragged the individual over the windward side. We didn't want the rib to land on the person and we kept him or her well away from the prop. In theory by using the mizzen as a 'wind-vane', one could possibly approach from the lee and remain reasonably settled in the water, avoid landing on top of the person and keep him/her well away from the engine. Nonetheless, using the foremast as a hoist somehow conjures up images of the dangling person frantically trying to avoid banging into the pointy end of the boat, not to mention the anchor(s). That would probably be the case even in a 1 metre swell. If MOB is a concern, maybe get some advice from the coastguard. They must have good gear and pretty efficient ways of doing it.
