Comments on Questions and Answers
Anchors Aweigh!1. According to Eric Hiscock the most common reason an anchor will drag is because scope was inadequate. With 1145 responses in, 80% of quiz takers answered this correctly. I guess you can argue that a properly set anchor should have enough scope. But usually setting an anchor refers to backing down on it to bury it in the bottom. Also a good thing to do.2. In some situations only knowing the water depth will be ok. But to calculate the amount of rode required, you need to know the state of the tide, the amount of freeboard at the bow roller, and whether your depth sounder is adjusted per question 3. Only 38 % got this right.3. Per the ASA take the depth sounder reading, add the amount of freeboard at the bow roller, add the amount your transducer is underwater unless your depth sounder compensates for this, and add the amount the tide will come up (establish your scope at a high-tide depth). Multiply all of that by seven and let out that much rode. 44% got this right.4. Based on all of the protests on this one, I did a little more research. Basically it depends on which expert you read, and they are about evenly split between three and four as a scope for an all chain rode. Only 25% got this right, but in your hearts those of you who answered four will know you had a good answer too.5. All of the given answers are problems with an all chain rode. 85% got this right.6. The first boat in the anchorage sets the protocol. If you have some boats with only one anchor and some with two, the differing swing room requirements will create chaos if the wind shifts. It pays to look closely at the anchoring schemes of boaters in an anchorage before you drop yours. 52% got this correct.7. No tricks here! If you are anchored in tidal waters and there's no wind, tidal currents are very likely to shift your boat's position 180 degrees. In many areas the relative heating and cooling rates of land and water create reversing on and offshore winds during night and day. How do you comepnsate for this in an anchorage? Any of the three answers will work to reduce swing room and keep your anchor from having to reset. Will you be held off a lee shore part of the time? Sure, but if the anchorage is almost landlocked you'll be anchored off a lee shore almost all of the time. No big problem. 58% got this right.8. A sentinel or a kellet is a weight you lower down your anchor rode. It absorbs some of the pull your boat exerts when being blown at anchor, enabling the shank of the anchor to remain in the desirable horizontal position for holding purposes. It also can reduce swing room needs and help keep your rode from fouling on the keel. 57% got this right.9. I figured this question would start an argument. Everybody likes his/her own anchor--at least until it drags one night. Rousmaniere chooses the plow anchor as the best all around. He comments that different anchors are optimized for different bottoms, the fisherman or yachtsmen for example being the best for a rocky bottom. The plow holds well in most conditions and it's weight enables it to bury in grass where lighter anchors might fail to bite. My CQR has worked well for me, but we almost always anchor in mud. Practical Sailor has run some excellent articles on the setting and holding capabilities of different anchor designs in different bottoms. They make for good reading. 44% agreed with Rousmaniere's opinion.10. The best way to break out a stuck anchor is to go over the top of it and pull from the direction opposite to which it is set. Be careful not to foul your rode on the prop! 86% got this right.As always, we hope you had fun and maybe learned something.Gary WyngardenS/V Shibumi H335
