    What is up with those oar locks? Just a pin and a hole to wallow in?

      North Breton tradition. Rocky coastline, large tidal flow and headlands creating inshore chop for working shellfisherman. Sea oarlocks are by tradition here captive to prevent the oars lifting out of the oarlock as the boat heals in waves. The pin is cheap and easily procured, replaced and even floats if wood. Traditionally you put a round pin into a square hole so if it breaks you can still pull it out. Using the hardwood pads attached to the oar shaft reduces wear compared to softwood and leathers/ is replaceable. The twin holes allows you to vary the inboard to outboard ratio for loaded and unloaded rowing gearing, and also to adjust to the fore and aft inter oarlock half beams.

      With a weighted inboard end, when tending crab pots the coukd just let go of the oars and they stay in the boat ready for action. They dont slip in the oarlock like a modern one can.

      The Portland Lerret on the other side of the Channel working a similar tidal eddy off Weymouth used the same system.

      The breton fishermen developed simple but sophisticated boat systems where they could.

      Open oarlocks as we now use are a flat water racing oarlock, not traditionally used on sea boats. The obsession with bronze oarlocks is also misplaced. The iron age followed the bronze age for good reason. Bronze oarlocks are prone to snapping if imperfectly cast. Its a durable but quite weak material in small small boat scantlings.

          On a similar theme,some while ago we had a local small boat builder whose literature stated "no castings are used on our boats".A good casting may have it's place but how many of us can identify a good one?

                            Creizic doesn't compare to Ilur very well, at least to my eye. I had been admiring the design too, right up to the last picture.

                              Huge dif in weight. one about half the other, so it's good you could see the dif.

                                Looks like that last picture was probably taken with a telephoto lens, which will bring the aft boat forward in a way that doesn't do justice to the amount of space between the boats...and therefor distorts the comparison. There's an eye thing going on there that actually makes it less useful for comparison, I think. Can't speak to it on technical terms, maybe someone else can.
