Mike is correct, special production of only 25 Silver Anniversary Edition B-31s. Bertram discontinued the production of the 31 after the 1981 year model, so they had a continuous run for 20 years. Then they offered the limited edition model in 1986 to celebrate the 25th anniversary of the boat that put Bertram Yacht on the map.......and what a run it was!
I don't know what 3208 stands for, I was told that she still has the original gas motors. Maybe 320 hp.
It is very very rare to find a boat with inboard gas motors in Greece, and I think in Europe too.
Gas is for outboards (mostly inflatables) and some in/out ones.
I would think that Gert would know the boat. Gert's 31 is gas powered. He took me for a spin on his boat a little over a month ago. What a beautiful boat and boat yard he has over there. Thanks Gert for the amazing hospitality. I was wondering how the beignets turned out.... We didn't drink any clears, but Gert has a great bar with a keg of local brew on tap. I don't recommend trying to go beer for beer with him. For those of you that have not seen Gert in person, he's about 6 foot 7 inches tall.
I don't think the boat spent anytime in Amsterdam; I was told that she is owned by a shipowner who registered her in the Netherlands for fiscal reasons.
By the way, please tell your brother that after the summer is over I will be able to give him all the details he wishes to know on my solar panel/refrigerator installation; I know how the system behaves now, but after a few weeks' hard use I will know more details on consumptions etc. Thanx.
