Everything is a compromise. Many variables;
how high are the davits
how bouyant is your stern design?
How conservative are you about weather
Are you sailing around the Capes? etc.
If I was sailing the roaring 40's or around the capes etc, then no, I wouldnt have the dink on the davits
. Otherwise I likely would.
You dont have to have a RIB
if that's the compromise you like. They are the workhorse of most cruisers though.
Here's a question: Are you more likely to have to cut away and abandon a RIB
on the davits due to weather
? or more likely to not have a dingy from a defective air floor in Timbuktu ? My guess is the latter!
