Keel Fillet

The Dudlex Dix design requires to reinforce the 12 mm thick backbone with 300 g/m² fibreglass fabric over an epoxy fillet on the inside of the hull.
I decided to make my TRÄHOLM  more robust. The thickness of TRÄHOLM's backbone is 20 mm and the fillet is covered with two layers 187 g/m² fibreglass fabric.

 

 

Keel Construction Detail

The hull has been coated with biaxial fibreglass of 600 g/m² weight. Steerboard and portside  coating overlap the keel by about 10 cm. Additionally the keel has been coated with one layer 187 g/m² fabric of 150 mm width and an additional layer 187 g/m² fabric of 75 mm width. Inside of the hull the keel-backbone has been reinforced with an high density epoxy fillet and two layers 187 g/m² fabric.

Satellite View of my Boat

Obviously, the "Google Satellite" flew over my greenhouse ships-yard shortly after turning the hull and has documented the new situation.

Keel Foil Slot

I covered the keel foil slot for the sake of simplicity during glass coating of the hull. Now I reopened it. For this task it was quite convenient that the hull can easily be tilt.

Water In The Boat

Not the boat but the greenhouse roof is leaking. I have scooped about an half liter of water and stretched a tarp over the boat until the roof is repaired.

Successfully Turned Hull

The somewhat expensive preparation has paid off. The turning of the hull was done in 10 minutes and no one came up a sweat. 

Preparations For Turning Over The Hull Finished

I was doing some remaining work on the hull turning device. This Friday it will show whether the device is strong and stiff enough for the task.
