I could go on at length about Scottish racing sailboat designers and yards based on the Clyde, back in the 1920's through 1940's but I'll spare you.
What I WILL do is go backto Ian Oughtred again, for one particularly, incredibly cool project he did. OK, everybody knows about viking longboats. What folks don't think about much are the Viking knarrs....yes, that's where the Class's name comes from. While the Longships were meant to take people the knarrs were merchant ships, designed to carry animals, lumber, grain and so on.
Well, in the Highlands of Scotland, along the north coast, the Longships were observed and a variation on the longship developed. The big, big change here, was that the Highland scots invented a new thing. It was kind of revolutionary.
--> The rudder.
Before that invention, all ships were steered with steering oars. Well, we all know what a royal paint THAT is. The style of ship that was developed was called a birlinn. There are stone carvings of ancient birlinns, but none have survived to this day.
Here is a sixteenth century (1500's, roughly Henry VIII's time) of a birlinn, clearly showing the rudder.
here's an EIGHTH CENTURY carving of a birlinn, on a tombstone again clearly showing the rudder...also the forestay and typing square-rigger yard rigging.
I, personally in a visit to Scotland in 2014, have seen thirteen to fifteenth century gravestones much like these. The sword motif is common, so are the intertwined roses. However, the birlinns are not.... but the fact that a birlinn shows up, prominantly on a gravestone of that age indicates how common, but yet important they were.
Well, Ian Oughtred drew up a lovely skiff for a group called the Gal Gael. Gal Gael is a foundation in Glasgow which aims to take drug addicted, alcohol addicted, and generally troubled Glaswegians, and teach them a trade. Much of the traditional industry of Glasgow is gone and that City has a pretty seedy and violent underbelly. Gal Gael aims to help with that though, primarily woodworking skills, but also other skills. Here's GalGael -

. Well, what Ian designed was the Saint Ayles Skiff, which is a pretty sophisticated, multi-plank boat.
After the enormous Saint Ayles skiff success, there are upwards of 40 of them, now, and rowing clubs all over Scotland use them... Ian took on the project of designing a birlinn.
