I only learned about these halfway through my modeling adventures and have only detailed them a few times. There is a great description of all the parts in this area in Volume II, page 78 of Dave Antscherl's
The Fully Framed Model. More detail can be seen in his drawings below. These parts were used to support the bucklers. Blind (solid) bucklers blocked the hawse holes when the ship was at sea, and the riding (two piece) bucklers were used to block the holes around the hawser while moored. Just as an aside,
The Fully Framed Model series volumes, especially I, II, and IV are great teaching books for any ship modeler, be it kit or scratch.
