I've just had a quotes ( today) for launching a 55ft n/b, off road transport. The quotes are for launching in the Midlands, approx 3 miles apart.
The first , a large marina, did not have it's own crane .They advised me to contact direct the crane company they use - I was quoted £1,800 or if I fitted in with when they wanted to do it £1,200
The second, a much smaller company, has it's own crane on site and quoted £350 + vat.
What a difference .
I 've also been quoted £200 - £250 to have it craned on to the transport. Lifts must be cheaper in Lancashire
