Stayed in Bancroft Basin. Rang Steve at Evesham marina, and he's agreed that Curtis will call in on Monday with a new set of batteries since he's over here anyway. Great that this avoids us having to do the return trip to Evesham. Clear from (a) the amount of engine time we need when moored up for a day and (b) the amount of charge they hold and (c) the rate of discharge with very little load, that the batteries really do need to be replaced. But they probably are 6½ years old.
0 miles, 4 hours engine time.
