Intheboatshed.net reader Erwin van Doeselaar has found a set of plans for the International 12 clinker built racing dinghy online.
They can be found at the Fries Scheepvaart Museum website and can be seen here.
I gather these are considered out of date and that a racing boat could not be built from them, though I’m not clear whether this is because they would not conform to class rules or whether a boat built from them might be too slow to win. However, I must say I find these little boats designed to be fast and fun very appealing – check out that transverse section.
But I’d hate to tip one over!
