One comment, I would be very careful to join a convoy. I would be really painful to have to run at 2-3 two knots for 500 miles because we are all staying with a towed vessel. I think that would end my wife's open ocean cruising with me. To have to do this because a owner has not taken the time, money or does not have the right vessel would really be frustrating. One of the reasons I did the NAR is because Nordhavn set high standards for the boat design equipment, and inspected every vessel before departure. I think one of the reasons was because they were going to have to do the towing.
