Final answer:
Anchoring from the stern alone is suboptimal because it may cause the boat to position incorrectly, causing discomfort, instability, and potential damage due to weakness in the stern design against wave action. Proper anchoring provides stability and control, especially in rough conditions. A combination of bow and stern anchoring is advised for optimal boat safety and control.
Step-by-step explanation:
Why is it best to avoid anchoring from the stern alone? Anchoring from the stern can be problematic due to several reasons. When a boat is anchored from the stern alone, it may not position itself properly into the wind or current, which can result in increased drag on the anchor and potential instability. Additionally, the shape and design of most boats are intended to cleave through water with the bow leading; the stern is not usually designed to withstand continuous wave action which can cause both discomfort and possible damage to the boat.
In the scenario where wind and wave directions conflict, as per the given text, anchoring solely from the stern can lead to an awkward position, putting excessive strain on the stern, the anchor line, or both. Furthermore, in the case of the oiler having difficulty with a thin oar and the risk of swamping described, anchoring from the stern does not aid in stability or control, which are vital in challenging conditions. It's also more challenging to control the boat's movement and protect against water ingress.
Maintaining a proper anchoring system is essential in a difficult operating environment, and stern anchoring alone does not provide optimal control or security for a boat. A combination of bow and stern anchors, often set in a 'V' configuration, can ensure that the boat faces waves or current correctly, thus minimizing the risk of swamping and providing a stable platform. This is especially important given the relentless nature of the sea, as described in the narrative, where each wave presents a new challenge.
