I have a 1983 Contessa 26, hull #312, that was manufactured late 1983 and shown at the 1984 Toronto Boat Show. The interior in the photos is a similar layout to mine; However, mine originally came with a 2 burner stove that was fixed in place beside the sink.
The format of the HIN is consistent, so I suspect it's a typo. Perhaps #328?
Have you hoisted the sails to check for a sail number?
It looks like a clean little Contessa; Not many frills but simple and clean. I hope you had the decks measured for moisture. In three years of searching for Contessas, I only found mine that had dry decks - even now, I suspect my surveyor missed a few spots.
I'm curious to know about how the two things work;
1. Force 10 Diesel Heater. I've considered this but have been told it's not worth the investment. How does it work for you?
2. The Yanmar 10HP. I may need to repower the boat in a few years. Everyone tells me I should get another 20 years from the original Farymann, but I have my doubts. How does it run? Can it get you to hull speed?
Isn't it illegal to remove the HIN plate?
