No experienced sailor wishes to be in a storm. It is potentially damaging to the boat and a great physical and mental strain for skipper and crew. And it is by no means unreasonable to assume that something could go wrong. When someone at the bar tells glamorous stories of sailing in wild seas, much of it can be attributed to the beer and a vivid imagination! In reality, we are talking about hard work, major discomfort and danger. On a crazily pitching and heaving boat, normal tasks become tough struggles. Lungeing for a hold somewhere; fighting against the wildly flapping sailcloth; fumbling with a knot which suddenly will not tie; cursing cold fingers and that horrible icy wetness creeping down your neck.
Into one's thoughts creep anxiety and even fear: Does the helmsman see the huge wave piling up behind us? Watch out! Wow, those leeward shrouds are whipping about; I hope the crosstrees can take the strain! Have they ever been as loose as this before? Just pray that the mast is OK. Then there's the desperate desire to check the position when you've only done it a few moments ago - have we still got plenty of sea to leeward? I can't go below to check now...
Routine helps. With plenty of experience under your belt, you'll be less likely to get worried about a storm and stay much calmer. Still, it is unlikely that you'll ever get blase about heavy weather — big seas can always command respect.
