Title: Ballast weight
Post by: Lord Nelson on September 11, 2014, 08:17:00 PM

HMS Volcano from Marks Model Bits. Length 95cm. Beam 17 cm.Can anyone please give me a ballpark figure for the all up weight of this completed model, I am particularly interested to know how much ballast would be needed. I appreciate an accurate estimate is not possible.

Thanks, Terry

The hull I am considering is Paddle tug HMS Volcano (renamed HMS Volatile in 1919). I was hoping that the basic hull dimensions given would be enough info to answer my query. PD's I bow to your superior knowledge, and only ask for a rough estimate.

Lordly greetings.

Hi Terry

Dromedary class tugs displaced about 700 tons and were 144' BP, so as your model is 1:48 scale we could try the cube rule.  Assuming the hull is to scale (which should be a reasonable assumption from a John R Haynes mould) she should displace 700 * 1000 /(48*48*48) kg, so somewhere between 6 and 6.5 kg seems reasonable.  Probably toward the lower end if you are planning on a freshwater boat.

All the best
Brian

Thanks Brian, exactly what I needed to know.
