A small model of a boat, originally built by Messrs. J.W. MacKay, at Newton Boatyard in Ayr, that was rescued from a west coast Scottish beach. Believed to have served as a rental boat in Whiting Bay in the 1970s, this was redrawn from a 3D scan of the real boat. I intend to name this boat 'Shearwater' when it is finally revived into seaworthy state. I've included both the nice 'shipshape' version as well as the rotten upside down version, modelled after how I found it.

This could conceivably be made into a nice RC boat if printed at a larger scale as well. I've included a 1:10 scale hull in three parts which glue together to form a pretty good fibreglass proxy. I suggest using Dichloromethane as a glue for PLA, as it bonds well and doesn't leave a weak spot. It doesn't have the textural issues that a wooden boat would have and can be sanded smooth to look like GRP. To obtain a good GRP texture on the interior, I found that gluing in a layer of fine non-woven garden mesh, then varnishing it down, produces a very realistic chopped-strand effect.
As in my photographs, the woodwork will need to be added by hand afterwards.

To print the 1/10 hull, keep the print speed very low. 40mm/s or below. The drag of the nozzle on the part as it prints will warp the shape and result in some funny curves if you don't. It should print without supports.

As drawn, this boat is 18' (5.5m) long, coming out to 63.5mm at 1:87 scale.

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.

I've also included the original 3D scan, in case it's useful to anybody for whatever reason!
