As the owner of a similar size motor sailer (have a look at my gallery) my first thought would be to say that it may not make much headway to windward but would be fine with the wind on the beam. Other failing of motor sailers is their reluctance to come about, its not the first time i have had to use the engine to get me out of irons.
Howsoever that said and bearing in mind, my hull is more motorboat than yacht, the reviews I have read on the Cox Master Mariner indicate a strong following and many stating that they sail pretty well. I have noticed however that there is another Cox 22 motor sailer which does look a bit more motor boaty under the water line.
The great advantage of this type of boat is the dual steering position. Here is a link to a web site.
I very nearly bought one of these a couple of years ago. Impressive little boat, seem very well built and safe feeling.
My missus didn't like it :-(
Ended up with my current Colvic Watson, that was offered at a knockdown price. Missus likes it a bit
I think the tacking issue is common in light airs on many wheelhouse style motorsailers. Below F3 Rhoda Rose likes the engin ticking over to push her through the wind. F4 and above she is fine though
Hi Graham. I am the owner of Jackdaw a Cox Master Mariner and live in Fowey Cornwall. My boat is in the yard at present and l have to prepare it ready for launch in early April. It needs a good wash down and antifouling ready for the season. Get in touch and l can show you round.

I am the owner of Jackdaw which is moored at the Gridirons pontoon on the Fowey River. I met the owner of Dilemma before Christmas, he has renamed the boat Agnes and this is now up for sale. It is a nice example of a Master Mariner built by Priorycraft I think with round portholes.
