The shroud stanchions in later 8m Catalacs are identical to those on the 9m. They have abot a 1ft footprint fore and aft on the deck
, which attaches through the deck
to angle brackets in the saloon
and the forward cabins. These angle brackets take the load from the shroud and the deck, and transfer it to the ply/grp bulkhead that forms the front end of the saloon
The actual shroud stanchion is designed so that the pivot point of the main shroud is about 1" lower than the pivot point on the tabernacle. Thus when lowering the mast, you slack off the rigging
screw, but leave the shroud rigged, and it acts as a stabiliser for the mast as it is raised/lowered.
The shroud stanchion has another fitting at the aft end, and this is on the deck. This where the aft baby stay goes.
The shroud stanchion has one more connector. This is at the forward end of the stanchion, and is located vertically at the same height as the hole in the bottom of the mast (which is used for the mast lowering device - basically a long scaffolding pole with a spike at one end, and connector positions at the other) These connectors are used for stays that go from the shroud stanchion to the forward end of the mast lowering device, and thus stabilise this pole.
The spinnaker halyard
and at least one other hallyard are connected to the top of the mast lowering device. The main sheets
are fitted block to block on the underneath of the device, and secured to the large anchoring
cleat on the foredeck. With these secured, you can follow the instructions on Rick's site for mast lowering.
If that is not clear ask for further details.
