Daisy, I sail in a part of Canada
with many canals. Both air draft
are a going concern for us.
Yesterday I had to push my 4'8" keel
through significant mud to get into dock
, and today I am sitting with a bit of a list, in mud at another dock
I was chit chatting with the skipper
of the only other sailboat in the moorage and discovered that he is sitting clear of the bottom in a 35' sailboat.
His boat is a Tanzer 10.5 swing keel
. The boat is a centre cockpit
and would be very tight to pass through 8'9" with a mast
, but if he stowed it to the side of his cockpit
, I think he could make it.
A Tanzer 10.5 in the UK would be a rare find indeed but boats like you are looking for do exist.
If I can recommend a course of action with regards to operating in very shallow water
, I find a powerful engine
and serious prop help to get you through the mud.
You must absolutely be able to clear the cill of the lock if you are to be succesful. There is no powering through concrete.
