Hi;
I have done many of those vessels as mentioned in the "Lobster Boat" Post. To me any vessel is worth restoring or rescuing. Why? Well, Most times, although the family requesting the work mostly ignored the vessel in question, til it laid in a box terribly broken by some calamity, They suddenly feel it's absence from their environment.
So what to do in these cases? The best work you can. Neither enhancing( Unless they ask) nor doing anything that detracts from the original. This in itself can be a challenge. I did one once that had been built entirely of reeds and reed fibre. It had been badly scorched in a house fire.
First off, where the heck do I get new reeds? A Chair maker in Pine Bluff, Arkansas came to the rescue. A friend of my spouse's, she was told by my wife of my Predicament. She offered dried and green reed material in the sizes needed, and only asked that I let her see the finished product. The Missus had already shown her the scorched remains.
Three months later the ship, fully restored, sat in it's former place of glory, not a line or plank or other part showing any sign of the scorching and crumbling it recieved. I learned some new skills and seeing the faces of the family members when "Mom and Dad's HoneyMoon Ship" was returned home, made the venture priceless.
Sure, I got paid. Most would've looked at it and just thrown it away. These oft ridiculed vessels sometimes pack a heckuva emotional wallop. Don't laugh, just get to work and do your best. You'll be glad you did!
