I am currently at Stanilands Thorne. On a trailer for blacking is a 30 year old narrowboat, the owner built it 30 years ago and employed a novel way of underwater protection.
He applied red lead to it then a coat of home made pitch to which he stuck 2 x 1 roofing felt tiles he then covered these with 2 coats of his pitch. He pulls it out ever 7 years to replace the tiles, the boat is only 4 mm plate and when stripped it still had no pitting!! he also paints the baseplate of the boat as well, it might seem hard work but as the old gent says it works the hull is perfik

Peter,I tend to agree with the old man, particularly about coating the base plate. Commercial boats were made to last a number of years and were worked hard. Leisure boats spend the majority of their time at a mooring, they do say two weeks work a year. Now I doubt a base plate coating would be removed by a say 5 weeks cruising a year. Even a lot of CCers only cruise one day in 14 days that is about 24 days a year, I suspect that a well applied baseplate coating would last two years and reduce the deterioration. If one thinks about the old commercial boats or hirer boats today they probably cruise 150/200 days a year, so maybe it would not help them. tin hat on
