Short of taking it to a local weighbridge ( Huntleys ? if they allow it ) on the way past 'no'. If its a problem I can tow a single tmrw...but need to know in advance please
Given the number of people required to lift a galley off the ground, I would estimate that they weigh between 120 and 160 kilos when "dry" and having been out of the water for 24 hours.
The trailer taking into consideration wheels, volume and constituents likely weighs between 250 and 350 kilos.
I would reckon around the 300 mark, which would give you a pay load of approximately 600 kilos dry and when the boats are wet it would likely be nearer 700 kilos.
Tarmac in Harts Farm Way (02392 478543) is a public weighbridge and can do the job tomorrow as long as the guy who is qualified to weigh vehicles is back off sick leave as expected. The cost is about £14 which our treasurer has OK’d.
I think we should do this on the way out tomorrow so let’s all get to the boat park promptly so we can load the boats up and get away asap.
The all up weight is within the unbraked 750 kg limit (for me it is 700kg due to MAM/GVW and insurance combination).
From memory the bare boats plus trailer were weighed at 645kg, by me, a couple of years ago. Oars and clobber don't add significantly to that, unless you are carrying clobber for other boats.
The only likely problem with the braked double trailer is :-
A) if the 3m height restriction is (or looks as if it is) broken. If you are sensible (i.e. no flagpoles sticking out of the top of the boat/trailer!) you won't need the message board in the drivers cab stating the overall height (in case of low bridges, etc.) or the "attendant" with the vehicle (or to have informed the police of the planned journey 2 days in advance).
B) if you don't have the (lit) trailer rear marker board on the back of the boats then you are restricted to max 2.0m overhang beyond the end of the trailer, and for more than 1.0m overhang you should have a warning tell-tale attached to the rear of the boat.
