Figure1:

This drawing shows the basic false keels of a plank on bulkhead (POB) ships. These are the most common types of false keels that come with kits. The upper one is a typical one piece keel while the lower one shows the additional components that go to make up this type of keel. The keels are basically identical to one another and the additional components shown in the bottom drawing could if needed be used on the upper keel if required.
