For boats under ~40' the masthead and stern lights may be replaced with a single all-around light, 1M above the sidelights. So I think a 3 person PWC with an all-around light high enough would meet the regs. Frankly I see a lot of boats, including the McRibs, that don't appear to meet the 1M vertical rule. So long as the all-around light is visible 360 deg at all times I'm sure you wouldn't be written up. As to where and how to mount said light ... the ones I saw had them mounted on a pole just aft of the seat, just where a tow pole would go.

I think the reasoning behind a "seperation" between the Red/Green and the "all around" white light is to lend
Perspective to what the "other boat" sees. It gives a sense of the length of the vessel and the changing
Perspective (angle), gives the "other vessel" an idea what angle/course "Our" boat is steering. The principle is difficult to describe so it that it makes sense.
If there were no seperation rules required between the Red/Green and "all around" White.....then we could put
ALL our lights on the same pole anywhere on the vessel.
