A traditional clinker boat in HO/OO scale. It's not specifically either scale as these boats, when built by hand, vary in size but not so much in proportion, so this can easily be scaled up or down (to a point) and still be a valid boat. If you scale height and width only it might become more of a rowing skiff, and if you scale the overall size it could be a dinghy rather than a full-on boat.
As it stands, the boat is 15' (4.5m) long in 1/87 scale or 13' (4m) in 1/76 scale. I've included some seats, but the seats will change with the size, and you may be better off making some yourself from 0.5mm styrene.
Included in the files is a water base. Real boats float, and when they sit in the water they inevitably displace some. This is a problem with so many model layouts I've seen, where the boats sit 'on' the water rather than 'in' it. The solution is obviously to use a waterline hull model, which is fine on larger boats, but fails when small boats are involved as you can normally see all the way down into the hull. To remedy this, there is a waterline base in the files. The idea behind this is to print it out, and then cut a matching hole into the water on the layout, and glue it in place. You can then apply any paint/silicone/water effects you want in and around it and be assured that the boat will fit nicely and sit at the correct level in the water when you're done.
To paint the model, first spray it a yellow ochre colour, then brush paint it with Van Dijk Brown OIL PAINT (needs to be oil paint). Then rub the oil paint off with tissues and cotton buds, this will leave you with the rich wooden colour in the photos. If you have carefully sanded off the print lines and sanded in a woodgrain texture to the planks, this will show up very nicely at this point. Best to do the oil paint in patches as it soaks in a bit whilst you go.
It could also probably be printed larger, but it's easier to ignore print lines on a smaller scale. I also haven't boolean combined any of the components so if you want to smash it up a bit, it should be possible to delete and cut planks, ribs etc to make a reasonable wrecked boat.
