Marine Designs
We have boat plans (both yacht designs, catamaran designs and power designs) for all sizes. From the 12ft Mushulu Dinghy stitch & glue yacht tender to the Oceansky 57 catamaran. We design timber boats, plywood boats, strip plank boats, fibreglass composite boats, steel and aluminum boats to very modern styling for both monohull designs or multihull designs, powerboat or sailboat and in round bilge, multi-chine or radius chine hull forms.
When building, the question most often asked is, what size fillet do I use?
So I thought I'd put this together.
The depth or throat of fillets should be equal to the thickness of the thickest piece of plywood being fastened and should extend outward from the centreline of the joint 1.5 to 2 times it's thickness.
Here I've provided fillet blade radius for various thicknesses in plywood.
As an example:
6mm plywood will require a minimum fillet blade radius of 14mm ( diameter of 28mm- refer diagram above)
Naturally this is to be applied to both sides of the joint to be fastened, and
tabbing to be applied
ie 200 gm cloth or Double Bias.
The above are minimum sizes
I hope this helps
Regards
Mark
