Thanks for the input guys,
and the photos.
Ref the keel.
My plans are.
The laminated boat keel will be hollow, and the drop keel will slot in. It will then have bolts going horizontally through both. I indend to set a nut into the boat keel on the far side. This will be for speed/ease of assembly, and allows for interchangable keel lengths if needed.
I know there will be some drag, but this is not a racing yacht and a boat this beamy has drag
I thought about using the vertical nut, I have one on my other boat (below the waterline no probs) but it is fidly and difficult to get to. Also this part of the boat is where the radio tray will be, so a tube up to the deck may not be straight forward.
I want to keep the ballast weight close to the recommended 4kg. As you say MCR, with 20lbs you need to plan your sailing.
I will be compromising on rigging and detail as I want this boat to be usable daily. Ease of use will be the primary concern with this model.
For example, my keel will be 21-22mm wide, this is 3mm wider than standard. It suits the materials I have and will be extra strong.
- 9mm core
- 6mm sides
- thin layer of glass to sandwich.
