As some of you know, my girlfriend and I have recently bought a Dart 15 and are looking forward to many an afternoon of sailing. The thing is, my dearly beloved has only had experience of the tame Dart 16, which, so far as I've been able to test, can't be pitchpoled... but of course the Dart 15 & 18 are different beasts altogether. So, not wanting to put poor Ola off at the first hurdle, does anyone have any tips on how to avoid the dreaded nose-dive in general non-racing sailing please?
