Stringers in hull

Next after moulding the hull is to reinforce it with a stringer grid. This is made of foam and will be heavily laminated with fibreglass. The fibre is the real strength forming a box section. You can see how many stringers are there down under the waterline.


In the middle you can see the keel box. The keel will be set in this and bolted in. When the keel is retracted it will swing up into this box. This is why no water comes into the boat from the lifting keel ;-)


Here is a shot from a few days ago crossing from Exuma Islands to Eleuthera - 40 miles of water only 15 feet deep. I went overboard to get film of the boat passing near a coral head (which was about 30 meters diameter) you can see the outline of the keel plate set into the bottom of the boat. The keel is mostly retracted. We like to keep it this way if we are exploring in shallow water. This way it acts as a safety in case we come into shallower water than we meant to. The keel will touch first and we slow down (since the keel weighs 3500 pounds it acts as a brake).



With the keel up and retracted the bottom of the boat is flat in the centre so you can beach and sit flat. Here is a shot from a week ago in the Exumas where we beached Distant Shores on a sandbank. The boat is sitting safely on the keel plate and the prop skeg. Its low tide. There is roughly 3 feet of tide in the Bahamas.
