Thank you, Brian and Doug,
And, yes, Brian, your hardtop looks exactly what we intent to have, too.
It really looks as if it was part of the boat ever since. Maybe you find some time to show the details.
Particularly I'd be interested in the connection between hardtop an this arch/bow of the doghouse.
It looks as if it was one piece from the windscreen to aft. (We are looking for a way to keep the "sunroof".)
Is it fiber glass/sandwich? And it reaches forward over the windscreen, doesn't it?
We are not in a hurry, but if you found some time to take more photos, it would help us a lot.
No holding tank means: We pump everything over board, as in the old days. (However, this is coming to an end anyway, as they are going to change the laws. Then also old boats will need to have holding tanks).
Here you may find an interesting solution (the text is all Dutch, the pictures, however, are pretty self-explaining I guess)

Below some pics of a different solution (within the "Albin 25 Galleries"
http://www.albin25.eu/mega-picture-gallery on our web site you may find even a few more examples for holding tank installations).

The Eberspacher is a diesel heater.

There is no "cheap" reliable boat heating anyway, and the Eberspacher are maybe even more expensive than others (at least here the main unit - without ductwork - is about 1100 USD without installation etc.), but I like the idea of having something where you turn the switch and it does its job plus no need of an additional type of fuel, like petroleum or so.
A very similar type of heating but fired by propane is also very common here

I think they don't sell Truma in the US or CDN, however, I am very sure there is a similar thing overthere, too.
In our situation, we prefer the diesel-heating, as diesel is easier and more convenient to bunker and to get (at the gas station you won't get propane here).
The space on the starboard side just above the battery compartment was actually designed by Albin for Eberspacher heatings (at least the A25 brochure says so).
