Add floats, 50/50 charity arrangements with the RNLI. (Add some MRT type charity funding, if any hills in the area) One or two more bases, every few miles around UK. Leave the dodgy 240 mile out to sea jobs and the night over water hover stuff to the big boys and girls.
Three o' clock. Target sighted!
