Question 70 Deck General

The correct answer is B) The keel step. The keel step is the part of the boat's structure where the bottom of the mast rests on the keel. This is the proper terminology used in the context of sailboat construction and rigging. The keel step provides a secure foundation for the mast and transfers the weight and forces exerted by the mast down into the keel, which is the main structural backbone of the vessel. The other answer choices are not the correct terminology. The foot keel, keel sole, and heel step refer to different parts of the boat's keel structure, but do not specifically describe the location where the mast is supported.
