Hi Barbara B.
Thanks for comments.
I don't know where the name coble originated but it looks as though it should be pronounced cobble. I am retired now but I served my apprenticeship as a shipwright and boatbuilder in the late 1950s and early 1960s building wooden inshore trawlers and small boats. It is a dying trade now as most small boats are now fibreglass.
The one I have drawn is of a 24ft in length but there were larger ones. They were open boats with a crew of two or three and mainly went out long lining and potting. They were hardy men and could be at sea for two or three days especially if the were caught out in bad weather and had to sit it out offshore until it was safe enough to beach the boat.
Sorry you were seasick on your fishing trip. I can sympathize with you have suffered the same fate on quite a few occasions.
Kind regards.
Mike
