I actually used a bait boat that i have since sold, spod would do the job just the same but i have to admit although i will not be getting another boat for rhis country i would concider renting one when i go to france this year purel due to the size of the bed of bait i put out and the time a boat saves you.
Rig wise i was mainly using short hybrid hooklengths size 6 and 8 longshank hooks, with pva bags of pellets but mainly my own stick mix for a bit of extra attraction.
you will have to let me know how you get on!
