We sail in the
Chesapeake Bay on our 34’ sailboat, and sometimes we carry two kayaks on trips of less than 40 nm each way. Before we used to tow them, which was Ok most of the time (during a thunderstorm one was airborne a couple of times for quite a long time).
Docking was a little complicated, and while towing they would eventually bang against each other.
More recently we started to carry them on
deck. We tie them together bow to bow, stern to stern, with bungee cords passing under the grab rails (see bottom left of the picture). In rough
weather we tie them more securely. Any
work around the
mast gets messy, and they block the view from the
cockpit, but the joy of kayaking in places like the Rhode or Wye rivers is worth the trouble.
