Hi James. Mine was the first response (since deleted) to your original question.
I think you will be more than pleased with your choice of Andersen 40 ST winches.
Before you fit them you will have to take the drums off so you can through bolt the bases. When you do that you will see how beautifully they are built.
When the Swedes or Norwegians build something, they do it for keeps. A fair bet is that those winches will outlast you and your boat. Indestructable!!
I have a pair of 40 STs and a pair of 28 STs and a pair of 34 ft yachts, a VDS and an S&S. Whichever yacht we decide to keep the Andersens will be on. Cheers Cisco.
