One big issue to watch for on IP''s are the rudders. IP''s actually have a post hung spade rudder with a fairly lightly built strap to prevent warps from getting to the rudder. In talking to yard owners, these rudders seem to be quite vulnerable as they are close to the depth of the keel where a more normal spade rudder is normally considerably shallower in depth than the keel.
They seem to be at their best in a pretty narrow range of windspeeds (14 to 20 knots of windspeed) In lighter air the IPs have a lot of wetted surface and a pretty small amount of sail area relative to their drag. In winds heavier than 20 knots, the large drag of these boats rears its head again, requiring the carrying of more sail area than the stability of the boat seems to warrant.
