Hello. Yes, I have a Compromis 909, which I have owned for two years, having lived aboard for the last 18 months. Not sure what specific info you want, but as a summary...
...the Compromis 909 is actually 9.45 metres (mine is 9.65 LOA, as it has a bow roller for anchor). They were built throughout the 1980's, designed by Frans Maas, built in Lelystad, Holland.
...the Compromis 909 has a great amount of interior space for the size of boat. My wife, cat and I have happily lived on board for the last 18 months, loving the centre-cockpit arrangement, which results in a good sized aft cabin.
...despite being a fairly heavy boat, it will produce a good turn of speed, but is a confidence-inspiring vessel that is a joy to handle.
...the manufacturers are renowned for producing strong, stable boats that are well made and long lasting.
Feel free to contact me should you require any further info. We love our Compromis 909 and would heartily recommend them.
