I'm a big fan of the earlier 48 and the 50 is an update.
Interior is very modern = square with light wood and contemporary fabrics.
PYB will sugared with me here but probably not the best 50fter you can buy but the residuals on both the 48 and 50 are quite low comparatively so a lot of boat can be had for a given amount of cash.
I had a 48 for 8 years great boat fully loaded and good use of cabin space, the fly was a bit poor design wise but overall very good boat.
There is one for sale in Mallorca as saw it this week and can be had at a great price good value for money is my view.
