No one answered me on the performance of the Seafarer 27 with MCM 4.3s so I had to find out myself! I bought the boat and now I am a proud Coronet owner!
To answer myself! At 2800 RPM and clean hull I get 18-20 knots and at 3200 RPM 23-24 knots and the fastest I have gone is 31 knots at 4000 RPM and I have another 4-500 RPM to go!
What a fantastic boat.
Congrats to your boat, Geoff!
My wife and I love this boat. We live on Vancouver Island and it is a marvelous cruising area.
