Until we went though the global tsunami in Thailand
, my wife always wanted to anchor
in shallow water
The tsunami taught us that it is much safer to anchor
in deep water
when you are cruising in tsunami high risk areas. If you are anchored in shallow water, when the harbor water empties out, you are sitting on the seabed waiting to get hit by a tsunami wave. The yachts anchored in deep water in Niharn Bay in Phuket, watched the current
go by at 10 to 15 knots as the water sloshed in and out of the bay, and as long as their anchor held, they were in great shape unless they bumped into another anchored yacht as the tsunami water changed directions.
One of the main advantages of a multihull
is being able to tuck up into the shallow water to get away from a crowd of monohulls. In certain situations, that can be a real benefit. But it can also get you in trouble in malaria zones when cruising around the world. Mosquitos don't mind flying out to the shallow areas, whereas those anchored farther offshore
don't have to worry about malaria mosquitos causing a problem at anchor. In Vanuatu
, yachties leave the shore and head
out to their offshore
yachts before the mosquitos come out in the late afternoon and evening.
Mosquitos and tsunamis are at the far ends of the "natural disaster" spectrum, but they can all ruin a cruise
if you anchor in the wrong location.
Where do you feel is the best place to anchor your multihull or monohull?
