love the 420
good boat and surprisingly for a British builder has a spacious engine room
suffers a bit the head sea and outside still looks a nice boat
inside the normal (usally) found wood is not liked much for market value cherry wood is preferred
A good pal of mine had one for about 2 years. Very good sea boat. Most of them had the Volvo tamd63p 370`s and were good for just short of 30 knots. He had 2 years virtually trouble free boating with her apart from the day we came back from lunch in Newhaven and the port shaft came away from the coupling and dissapeared through the stuffing gland with the commensurate ingress of water. Luckily the prop had hooked up on the rudder so a brief swim enabled me to shove it back through the hole and save the carpet. This obviously could happen to any shaft driven boat. On the whole a good solid Flybridge cruiser.
Good boat, owned one for 4 years, only sold as we traded up in size. Took her over to chanel islands many times, sometimes in poor conditions (6/7) for a flybridge cruiser. Nothing broke and took it well. Had some minor problems with the gear selection on the Volvo engines - to do with control adjustment but otherwise had a great time with her. Would I have one again? A big YES.
If your thinking of buying one the Fairline Phanton 40, old style one at about the same money is a good boat too.
The princess maple wood looks old and fades really bad, but general build is as good as it gets.
If its mid nineties check the windows if they are made of SS with an aluminium extrusion inside check for electolosis. The 560 & 360 of the period suffered from such and I should know.
