great answer.
thanks
hopefully if i put a cover on the boat, it might cut down on some of the air being caught also
and keep at 55
That was exactly my first thought. Put a full cover on the boat to keep as much air as possible from coming up under it. You could even go further and add a deck to the rack, since it looks like the boat sits low enough so there'd be almost no gap. Another thing you could do would be to make an air d@m (really? censoring "d@m"?) on the leading edge of the roof top to help deflect air from between the boat and the top of the cab. Third thing would be to carry the kayak upside down on top of the boat since it doesn't look like you can turn it towards the boat on the side mount.
On edit, x2 on the idea of setting the kayak under the boat, if the seats could be removed to allow it.
