I was wondering that Duncan , seems a bit strange for anyone to want to built a 106ft "model" just so they can fly r/c aircraft off/on it.

I know there are a few very large manned "models" ( one of the Graff Spee ) in the USA but there's absolutely nothing on this scale.

I wouldn't even contemplate the costs of building a 1/7th scale model of my families old 87ft trawler !!!

To get a 106ft "model" to the required safety levels would require commercial building methods in steel or grp , powered by 2 large marine diesels ( 106ft even lightly built will be over 100t ) of over 400hp just to get anywhere close to 8 knots any faster than say 10knots would need a pair of 650hp engines.

If you want to estimate the cost in fuel well 2 400hp engines at 100% power would be burning 70ltr/15.5 uk gallon per hour at a minimum and a pair of 650hp engines 114ltr/25.2 uk gallon per hour

I'll stick to 1/24th and 1/32nd models thanks
