There are a number of marinas along the Abruzzo coast. Boats can be hired for the day or longer with or without skipper. A couple of the hire companies are shown below, but a visit to the marina is probably the best bet.

Nautal - Private - GetMyBoat - Mautica - Idra II - Contravento Sailing

There are also about 6 sailing clubs along the coast and a list of them can be found here.
