I use quite a long pole, in the fishing rod holder, with a flag 'alpha' on, must be about 6 foot tall, and the flag is quite a large one. I would class it as being very visible.
On monday when I went scuba diving, anchored up, flag up, missus on boat and down I go, to about 10 metres depth. After about 15 minutes, I could hear the drone of an engine, and actually thought to myself, that sounds quite large and very close. When I resurfaced, my missus was furious, as one of the local pleasure ferrys/ sight seeing boats had come past, within about 6 metres of our boat............!
And these are meant to have professional skippers...!
