Fuel is a major factor on any trip but with a bit of homework i.e www.petrolprices.com
you can see where to buy the lower priced fuel, the difference between Wisbech and Yarmouth was up to 6p litre which calculated over the trip is £2-£3 pounds !
The Humver used to be a fantastic place to have a day out but now we are banned from ABP property then its worthless even going there.
ABP Goole is still pretty much OK as there are public footpaths running through the port so you can still get 90% of the ships whilst on public proprty.
The Trent and Ouse are still pretty much OK although I would suggest taking a mountain bike with you for Groves Wharf & Neap House as its much quicker than walking 2 miles down the bank.
Grimsby is OK for most ships on Freshney Terminal as they can be taken from the roadway. The ocks are a no go area.
Immingham is like fort knox, no chance of getting in, tankers on the IOT2 and 3 berths can be taken from a road that runs parallel to the riverbank, as can any ships in/out bound but they are at a distance.
Hull is also another no go place, there is a public walkway running parallel to the river where you can photograph anything on the North Gap in King George dock and anything inward/outward.
Same goes with the Alex Docks, there is a public walkway that follows the course of the River Humber and goes across the lock gates.
Same again for the Fish Docks at Hull, there is an overhead walkway which runs above some sheds resulting in ships being able to be photographed for at least 1/3rd of the dock.
Tide wise, a good place used to be off St Andrews quay where the ships used to pass within 200m of you but the swe Skitter channel has opened up and they are much more towards the North Bank now and well out of range so the Humber Bridge is the best option. Im not sure about North Ferriby anymore as I have not been there for a while so perhaps somebody could comment on that option ??
I did hear that ships passing Paull are quite close so that could be another option although I have not been there for 15+ years !
