Watching someone "
Handle" a single OR twin screw "straight inboard" WELL, in close quarters, can be a Distinct Pleasure when the operator knows what they are doing. When they don't, it can be excruciating to watch.
My experience over the past 40 years, both as a boat owner, and observer, has been that as a general rule, the skipper with the larger boat is much more likely to be competent at handling his boat than one who has a smaller boat, primarily because the smaller boat operator is likely a comparative novice. However, if that smaller boat is a Varnished Mahogany Antique..OR the larger boat is their first
McYacht, then all bets are off.
A sure fire way to identify a novice: ANY Size boat
Underway ...not actually preparing to dock or undock, steaming along with fenders swinging merrily over the side in the spray.
