I am at the time of life whereby boating could become a reality - i.e. financially and familywise. Could I please have some advice on the realities of running costs, how I can try it out to see if I like it, practicalities of maintenance, obtaining moorings, training I need and so on. I live near the Sharpness-Gloucester canal and would hope to have a boat nearby and be able to do both inland and coastal cruising. The advice I've had so far suggests a moderate sized cruiser between say 27-34 feet, twin diesel for the nominally best of both worlds. Any thoughts?
