So, have been slightly involved with an old Breton fishing boat. Dates from the 50's? and plank on frame. Had a step for a mast, but was fitted with an early Volvo Penta MD2.
We need to work out the weight to get a road legal trailer. He reckons over 1.5 Tons. Me, rather less.
So, on friday I looked in at the yard were it is currently parked and took off some girth measurments. With a length of 5 mt. That gave me 16 squ mt of planking. 16mm? Call it 20mm. Some type of pine, so used an average density and it worked out at 200kg . Framing and keel + other bits I guessed at double that, So 600kg. Engine is 220kg Stern gear, rudder, other bits?? Likely still under a ton?
Any comments?
