easy trip really we did it again a couple of weeks ago to cherbourg and St vaas on ours andwhiteshoes on his boat 2 hours ish back three hours ish there. Alderney during the summer as per Marks link 3 hours.
not much more really than a trip around the iow 60 miles give or take.
Just make sure you have the right heading or ya might end up going in the wrong direction as happened when on board another boat
will dig out some links later.
BruceH has an aux on his solent 6 hp i think which will push him at 6 kts. Our aux is sea start
and the other boats we go out with.
