Enchantress Aground

Avoid grounding by not taking chances or shortcuts to get through a rocky or shoal area. Go the long way round–it is only time. Do not rely on the GPS. Stay well off a lee shore. If you must go through a rocky area, or one with coral heads, keep a very close eye on the Forward Looking Sonar and post a lookout high up in the bow, with the sun behind him/her so s/he can visually pick out where the dangers lie.

If we go aground the approach is:

  1. What is the state of the tide? Is it rising or falling, and if so by how much? Is it a spring tide?
  2. If you go aground at the top of a spring tide, you must act very quickly or you could be stuck for a couple of weeks.
  3. If you go aground under power, immediately go hard astern and try to slide back out along the groove the keel made. If this doesn't work, go slow ahead while swinging the rudder back and forth to dig a wider groove, than after a few minutes again go hard astern. If this doesn't work, desist and kedge or sail off as below.
  4. If the tide is rising, you may be able to sail off. In any case, try to get the boat heading towards deep water.
    • If the wind is blowing from the shallow, back the jib to blow the head round, then tighten all sheets to heel the boat and sail off.
    • If the wind is going onto the shallows, gybe hard if you can and then trim the sheets in tight to heel the boat as she rounds up.
  5. A rising tide will likely drive you further into the shallows. If you cannot get off the shoal, then anchor the boat quickly to keep that from happening.
  6. To kedge the boat off, put the primary anchor (or stern anchor, or Fortress aluminium anchor) well out into deep water upwind or uptide with plenty of scope. Then winch in on the anchor windlass. At the same time try to heel the boat. With a big falling tide, this may have to be done FAST.
  7. Reduce the draft of the boat as much as possible:
    • Heel the boat towards the shallows: (a) push out the boom and have crew sit on the end; (b) take a halyard off in the dinghy and haul on it–carefully, this puts a lot of strain on the mast.)
    • Jettison heavy items into the dinghy or overboard and as a last resort  empty the water from the tanks..
  8. If you start to heel, close all portholes and hatches and thruhulls to keep water out of the down side. Do everything possible to make her heel towards the shallows. That way:
    • Water will be less likely to enter the boat as the tide rises.
    • The keel will slide down the bank into deeper water as the tide rises.
  9. To set an anchor from the dinghy:
    • Put the anchor in the bottom of the dinghy along with all of its warp on top of it, making sure the end of the warp is secured tightly to the boat;
    • Let the warp pay out from the dinghy as you go rather than being dragged through the water from the boat.
    • Be careful not to wrap the warp round the dinghy prop.
    • Drop the anchor from the dinghy quickly as soon as you're at the end of the warp.
  10. If you end up drying out, then put fenders, cushions, etc under the bilge to protect it from damage on the rocks. Consider rigging a leg (use the spinnaker pole).
  11. If you go over the side onto mud, always wear a safety line and have someone on board watch you. Walk fast in soft mud and walk on your toes. Take an oar as a walking stick. If you are taking gear with you (anchor, chain, etc) make a sled to drag them (cockpit grating, door, dinghy, etc.)
  12. If you should go aground in heavy surf and it looks like the boat may break up, consider scuttling her to reduce the pounding. Best to do this off a beach. Open all seacocks and remove hoses, open the portholes and hatches. If possible lay anchors to seaward and moor her to shore to hold her square. When the tide leaves her, so will the water inside. As the tide goes out, close the seacocks etc. and prepare to refloat the boat.
