sorry for the delay. been off air. I have had our E30 for 3 years. Had to get used to a lot of weather helm which requires reefing the main early. But otherwise its a good sailing craft. Some aspects to be aware of. Ours requires the prop shaft to come out forwards - the rudder skeg is in the way. So if you need to do any work on your bearing, stuffing box etc it can be more complex and $$.
We have found her very comfortable to stay onboard. The berths are a useful size and the layout works. But again, perhaps some have a different layout.
Ours has a wire halyard / wire halyard winch. This is not as easy to use as a rope halyard winch.
Ours has an anchor locker on the foredeck which extends into the forward V berth a lot. I don't like that aspect of the design, but I guess we could change it but instead use the forepeak for storage.
Arthur's yacht below looks like the buy of the decade. Ours was very basic but clean and tidy when bought. Have replaced rigging, foresail and stuffing box.
