Alberto Vila of the Tigre City Rowing Club in Argentina made a comment on a previous post containing a link to the website of the builder of their lovely traditional wooden rowing boats, and I think it deserves a post to itself.
Angel M. Gil builds boats in the traditional way, in various local woods and proper rivets. Google Translate adds its own charm to the site, for example one of the woods is described as 'cedar missionary: wood light of pleasant fragrance'. I so much want a boat light of pleasant fragrance.
There are several boatbuilders in the UK who would be capable of making this sort of thing, it's just that sliding seat rowing is now entirely in the hands of the high tech boat industry and are without exception made of plastic. A pity.
