We had a tiny little wooden cruiser like this on the Thames when I was very young, about 21 feet as I recall so even smaller. The decks and cabin roof used to leek in heavy rain and it had an engine than started on petrol but then switched to paraffin (kerosene), but it got us out on the water and some very fondly remembered family holidays.
The romantic in me says it would be a lovely boat for pottering around Chichester harbour, but the reality is that it's more likely to be an ongoing shore based woodwork project for many years.
I guess the outboard conversion might be more reliable than the
original engine but aesthetic is not.
