Agreed. Over sea haze, it's much better for everything but lookout to act as if you're in cloud: fly by reference to instruments, just keep alternating between that and a heads-out lookout - which does need a good degree of cockpit discipline, but is perfectly achievable by any reasonably current PPL.
