Mixed up,
I appreciate that your comments were well intended.
Or perhaps you know more about Nigelisom, than we do? I don't know.
But I don't see anything in his original post to suggest that he was going to try to "pull off" something. In fact he says quite clearly that his trip is Weather Dependent.
There is nothing wrong with a PPL "VFR Only" doing a trip to the Isle of Man. I am VFR only have have do a number of such trips. It's certainly posible to do safely, or as safe as over water flying can be.
The trick to VFR touring, is to make sure you have nothing at all planned for the day after your return (well no meetings etc), and nothing that can't be pushed back for the rest of the week. Important meetings, or approaching deadlines and VFR touring don't really go well together, in my experience. Once you do this, most of the pressure if taken away from you, and an extra day or two at your destination isn't too much of a problem.
