Hmm, well I managed to put an Oscar II prop on it so it somewhat looks the part. From everything I have seen on the Jack it was actually supposed to be quieter than the standard Permit because it had direct drive. Now they did have trouble with the seals on the shafts and drive system so this may have lead to noise later on. My understanding is that the worst part of the whole thing, the direct drive was so heavy it destroyed any efficiency gained by the contra-props and gave the Jack a .3 knot increase in speed over the standard Permit short hull.
