Surprisingly, it takes me under 3/4 an hour from arriving at Wareham to rounding brownsea castle during the summer. It normally takes a little longer getting back (as I'm not quite so eager). No faffing with trailers and slipways.
The weather looks favourable, the tides look reasonable and i will have earned my brownie points on Saturday by taking my missus out ALL day and missing the football :-) .... so .... my plan is to leave Wareham around 8am and get back to Wareham around 8pm.
What do you suggest for the time between?
