Hi, Faith - and yes, finding things in Aubrey''s writings was much easier 4 or 5 years and many articles ago!
I believe the hook-up that the Millards put on their boat can be seen at www.
dinghy-tow.com/ You''ll find pictures and a description of all the positives here, so consider this the sales pitch as well as a tutorial. Some of the downsides are that, when taking a slip, you''ll have to raise the dink vertically...and I''ve seen some pretty hairy events when a squall hits a boat with a dink stored in this fashion. (Keep in mind it''s smaller boats which tend to use this method because they are the ones for which davits and on-deck storage options aren''t possible). As I recall, Aubrey also describes an incident on the North Sea where the system failed in some fashion and led to some exciting moments.
In settled conditions and coastal or interisland sailing, this strikes me as a clever approach for the smaller boat. Just when secure stowage becomes critical - offshore or in tough weather - is IMO where the limitations of this system appear.
