Airtool, thats a good summary of the different types, but you forgot to include their names.
Straight boom = straight
Straight contour = bend down only
Universal contour = bend down AND back
Quad contour = bend down and quite a bit back/forwards
If Im not mistaken, the quad contour is actually meant for v-drives with aft mounted pylons- I would not want to run one on a direct drive. I have come across very few Straight Contours... most people use either the straight or Universal contour, the latter being more common.
The reason the straight boom is less popular in general is because most boats cant fit them. Direct Drive Correct Crafts (at least the ones prior to the 200) with their short windshields pushed forwards, were among the very few types of boats that could use them. The straight booms are my preference, one reason being that they are very easy to store.
