I can speak of their build quality and their sea keeping. Firstly, if you make a comparison based on the known build quality of motor vehicles, the Bavaria comes out as the VW of the boating world. That is by no means a criticism, since VW are renown for their economical design and reliability. Personally while fitting new Nav instruments, I was impressed with the way that the existing looms were run and they had even left a 'mouse' so that further wires could be run easily along the same route. Clean, simple and functional design throughout - very typical of the Germans
As to sea keeping. IMHO the ultimate test of any boat is how it makes you feel during a bad blow. Heaved-to in the Bay of Biscay, on delivery passage to Gibralter, the boat felt solid and secure, giving the (off watch) crew the confidence to go below for a brew!
