Ok so they're probably ships not boats. Photo taken in Ramsgate harbour.
The apparently old Naval Frigate? is the Grand Turk & was commisisoned by TV for the hornblower series. It was actually built in 1998 in Turkey as an exact replica. Funnily just after I saw her there was a newspaper article about her and she is actually up for sale at 3,000,000 pound.
The other more modern classic little ship I know nothing about except she is quite stunning and is registered in Gibralter. Gossip had it she belonged to a very rich person living somewhere local to Ramsgate. When I did a quick google I discovered a few others had posted similar photos on other sitesand that there is a hotel chain called 'Sans Souci". Coincidence ? I don't know.
Another one of the replica. Notice the modern bow thruster. (Sorry about the underdeveloped picture. New camera, hadn'r read manual.)
