Keel...

You can see that there is a flap of fiberglass... Turtle has jammed a little bar into the flap so it would be really easy to see... not that we needed it! Looking closely, we think that there was some bilge fluid in a void between the steel weight and the fiberglass skin on the keel. When we impacted, the fluid was blown out of the side of the keel.

Also, the first few feet of the keel looks like it was sanded down... We can see the various layers of fiberglass as though they are rings of a tree.

All of this will have to be cut away, back to the steel, allowed to dry out, then glassed over with about 40 layers of new fiberglass and epoxy. Since epoxy generates heat as it cures, we will be able to put on only 4 layers at a time, then wait until it has cured before adding more. The yard is estimating they will be able to add 4 layers, twice a day... so it will take 5 days just to glass it in. Of course the prep work will take a bunch of time before and then everything will have to be faired (made smooth and hydrodynamic), sealed with 6 or more layers of barrier coat (seals the fiberglass to keep the water from entering, then three coats of bottom paint (which discourage barnacles and other creatures from growing on the boat.)
