I plan to sail/motor to the IOW tomorrow which commits me to motoring/sailing from the IOW to Chi early Sunday morning. I can't go on the evening tide.

There seems to be lightening in the forecast, although they find it hard to predict and it's in and out of the forecast. (Currently out.) Certainly feels thundery right now in Chi.

Boat is a Corribee so not a tall mast but substantially taller than sea, obvs.

As the Clash so wisely queried, "Should I stay or should I go?".

Go. Otherwise you will never go anywhere.
The met office aren't showing any warnings at present and if they do I suspect that it is a low risk of them happening. Then add in the risk of being hit; so 1 million times 1 million makes the drive to the boat more dangerous ....

I hate sailing in thunderstorms.

Apart from the risk of a strike, there is also the risk of other extreme weather which often go with it.

Personally, I would keep a close eye on the forecast.

Get ready to go then check the radar on netweather.tv which should show any rain and they also have the ability to conjure up lightning strike information.

You can then leave - depending on what the situation looks like, put it off for an hour or two (I'm assuming you have a reasonable window) or resign yourself to the fact that you have to stay (or the boat does) until it sorts itself out.

Many years ago I was motor sailing, at night, up the Sound of Jura. 42 ft sloop, steel hull, wood mast, standing rigging not insulated from the hull. A thunderstorm decided to take the same route up the sound and passed over us. We had to drop the mainsail as the wind increased and veered through about 500 degrees, or perhaps the compass card slowly spun around. Boat and mast were the highest points for a mile or so around us. I was standing on the coachroof, stowing the sail and feeling very exposed watching multiple lightning strikes hit the water. We were not struck though the guy on the helm noticed flickering on the backstay (perhaps St Elmo's fire?) but the electronics continued to work. It was not raining much so the strikes were probably further away than I thought: its difficult to judge in the dark.

Isn't it easy to calculate the distance of a lightning strike, regardless of whether it's dark or light? Just a case of applying a simple formula (though I forget what it is) to the time lapse between the flash and the bang? (Due to the huge difference in the speeds of light and sound transmission.)
