The entrance to the harbour at Portreath. Although, for a north coast port Portreath is fairly sheltered by comparison this does not been it is completely sheltered. There was a moderate swell running this day and it is already starting to look a little hairy. Swells on the North Cornish coast get much, much bigger than this.
Now imagine trying to negotiate that narrow entrance with a fully loaded sailing ship! A frankly terrifying prospect in my opinion!
The two white structures either side of the picture are the Monkey House on the pier and the Pepperpot, a daymark. These were the only navigational aids available in the old days.
