The picture below shows my transom with the boom hardware installed. There are three pieces of hardware on the transom for the boom:
Rigging the Main Sail - After the mast has been secured with the fore and side stays, it is now time to put the boom on. The front of the boom has a hinged "mounting" fitting which is placed into the opening in the mast for the boom and sail slugs. You then slide the boom down to the height that you want it and secure the line attached to the bottom of the boom to the cleat on the lower part of the mast. This prevents the boom from riding up the mast and coming out of the opening.
The foot (bottom) of the main is a bolt rope and is feed into the slot in the top of the boom. It is then secured by a line at the end of the boom.
The luff (front) of the main sail is held to the mast using sail slugs. These are feed into the opening in the mast and pushed up past the opening. I use a "sail stop" to prevent the slugs from coming out of the opening in the mast. I also used a "sail stop" below the boom to keep it from sliding down the mast and hitting the top of the cabin when the main sail is taken down.
In order to be able to secure the sail quickly to the boom after I have dropped the sails, I installed a shock cord to replace my sail ties. I evenly spaced 4 eye straps along the port side of the boom and installed 3 hooks between them on the starboard side of the boom. I then threaded the shock cord through the eye hooks. When I drop the sails, I just get on the starboard side of the boom and pull the shock cord over the sail and secure it to the 3 hooks.
The “eye straps are just stainless steel “U” fasteners. That is, they screw onto the boom on both ends of the “U” fastener and have a raised “U’ shaped middle. that is where the shock cord is threaded. These are on one side of the boom. On the other side of the boom , I installed stainless steel hooks. These are installed in between the “U” fasteners in relation to the other side of the boom and are facing down. Then I threaded the “shock” cord through the “U” fasteners on one side of the mast. I took a long piece of shock cord and knotted it on both ends. When I dropped the main sail, I would “grab” the threaded shock cord on one side of the boom and stretch it over the sail. I would then hook it on the other side of the boom. I did not size the “shock” cord until I dropped the sails and tried my method, to make sure I had enough play to hold the sail in place. Then I knotted both ends and cut off the excess.

Swivel cam cleats Standing Rigging The picture to the left is one of my Spreaders (Stantion) that is used to hold the side
stay away from the mast. It is a 21 inch tube which is 5/8 of an inch in diameter. In the picture you can see the boot on the end to prevent chaffing of the sails.
When I purchased my Genoa, I was not familiar with Genoa tracks, so for simplicity, I installed two additional Swivel cam cleats on my coamings. The following picture shows you my original swivel cam cleats and the additional one I added on each side for the Genoa. The additional swivel cam cleats are 17" from the cabin on each side.
(Note: Measurements are given based on my mast [21 feet 4 inches]. They may vary depending on the length of your mast.)
In the picture to the left, where the stantion is fitted into the base on the mast, the tube is flattened for 2 and 1/2 inches on opposite sides to 1/2 of an inch diameter. This is to allow the stantion to rotate in the base on the mast.
After I removed the boot, in the picture
to the right, you can see the end of the stantion where it holds the side stay. There is a 1/2 inch slot in the end of the stantion and a bolt to hold the side stay in the slot.
The picture to the left is a turnbuckle at
the end of the fore stay. There is a similar
one on each of the side stays.
