I have actually seen the Satura pictured in the post in person. It's well, ummm unorthodox in many ways. Not sure how it sails but it looks like it may be okay in that regard....still, it's strange in some details.
The pilot house boat would be better if inclement or cold weather would be a significant factor. Also, it is or is approaching the definition of a motorsailer: note larger engine and shallower keel, but it is hard to compare since I didn't notice relative sail areas (I only looked at first page of each listing).
Edit -- Overlooked Saturna's interiorhelm. But the pilot-house boat would seem to have better visibility from its interiorhelm.
