That is one thing I really like about the Loose Cannon kits - you get everything you need to build a very decent model right out of the box. Of course, as your skills improve, you're going to be tempted to add things, and try new techniques, and make each model incrementally better than the last.
My first model in 30+ years was the Loose Cannon Victory ship. I thought I was doing really, really good to get the lifeboat falls on in something approaching a halfway decent manner, let alone the PE cargo boom rigging or even a few of the railings.
Now cut to my latest ship, a 1/700 Skywave Liberty ... I made all of the cargo boom rigging with my Waldron punch sets and stretched sprue; added all the watertight and other doors, every bit of railing, firehose racks and life rings (again, made with my Waldron sets); drilled out and added portholes; added styrene strip, sheet and tiny plastic discs to represent the weird 'armor'; and covered the hatches with 20 GMC 2 1/2-ton trucks, 5 Dodge weapons carriers, 4 Jeeps, 5 P-40s and 5 motor launches. Who says modelers don't know how to have fun!
And weebles, PM me if you want me to shoot you a copy of a generic cargo boom rigging diagram. It's wayyyyyyyyyyyy more than I would ever attempt, but it gives you a good general idea.
