The vacuum bagged hull is made of e glass/ epoxy/foam core composite construction with carbon reinforcements for all chainplate connections, mast collar, keel head area, bottom, hull stiffeners, rudder bearing.
These had once held a turnbuckle to a chainplate but I'd apparently decided they were bent, so I'd replaced them.
A moulded internal grid strengthens the skin and provides the pickup points for the chainplate and keel loads.
"The designers tell us the righting moment of the boat at different angles, and the chainplate width and give us a rig plan and we pick it up from there", explains Graetz.
The hull is a single-skin moulding reinforced by a structural inner moulding which is bonded and laminated to the outer skin and accepts the loads at pressure points such as chainplate tie rods, keel, and rudder.
The chainplates are also composite and fully laminated to the hull so they all have the same mechanical properties and create a single monolithic structure where everything works as one.
The biggest problems are metallic fasteners screwed or bolted through the dielectric shield to attach blocks, winches, stanchions, or chainplates. The differences in conductivity between the dielectric and the metallic fasteners such as screws, bolts, and rivets cause streamers to form at the fasteners and lightning leaders to be attracted to the metal.
This is obtained by using one material only (fiberglass), avoiding filler and silicone in the five key points: 50 mm composite main bulkhead resin bonded to the hull and most importantly of all to the deck; composite chainplates (instead of steel) vacuum bonded with 48 layers of uni--and bidirectional fibres; long tudinal, transverse and side girders are not an inner moulding construction, but are fully laminated and resin bonded to the hull; keel attachment provided with a 50 mm stainless steel AISI 316 mounting flange connected to the hull by means of no.
Don't get close to the shrouds/stays/ chainplates! Go below decks!
Outside shrouds with hull chainplates support the alloy rig, while up front the retractable prodder deploys for an asymmetric kite.
This B&R style design requires wide triangulation, so the three shrouds either side are located outboard on the gunwales with chainplates. This layout, with Genoa track inboard, leaves the deck nicely clear for working crew, though the wooden toerail won't be a comfortable hiking perch.
[] Run an eye over all the stainless steel gear--stanchions, pulpits, transoms, life rails, chainplates and cleats--for signs of wear and rust.
