Hey Gemma - no wonder your neighbour has a boat!
The slate chippings obelixx mentioned would be a good option as they're flat and less likely to stick. You could extend the path across to the shed though, so that you're on a firm surface for working between the veg plot and shed. If the whole plot is pretty wet and sticky I think you'll either have to invest in some drainage methods (either the soakaway, or tons of grit mixed in to the whole plot) to improve the other area or plant it up quite heavily with just pathways through it and a small paved or gravelled area for seating/dining.
...and maybe a bucket of water next to the veg plot to stick your feet in when you come out!
