Hi Liz,
I'm not an expert on wooden boats but (most) are very beautiful to see - especially when looked after - they can have a very graceful line that shows the love put into them by the builders.
I recognised quite a few from the link you posted - and of those they are mostly in good condition, but the boat industry over here is in dire trouble after the financial crisis and wooden boats do not fair so well with neglect over their fibreglass cousins.
Shannon Harbour was, for a long time, almost a graveyard for old boats that were either forgotten about or bought as projects by people ill advised on the amount of effort, time and money that is required for renovation and it was a sad place to visit. There has been much effort by Waterways Ireland to clean up the area in the last few years which involved removing most of the 'wrecks' but I am unsure how many were bought to be restored.
