Boat ID - Book front cover of John Vigor's "The Seaworthy Offshore Sailboat"

Hello

Does anyone know which boat is pictured on the front cover of John Vigor´s "The Seaworthy Offshore Sailboat" ?

Thank you and All the best (O:

 

For those who have misplaced their copy of Vigor's book, here is the cover photo:

 

With these cluttered side deck?
Not fair, I didn't read the book, and it's certainly a good book , but the covers choice don't give me any incentive to buy this book.
But I suppose I should buy it, been also a book fanatic.
Thank you for mentioning it both of you by the way

 

Thank you ImaginaryNumber for the front cover picture. I tried posting it myself, but obviously it didnt work.

 

- the inside of the book says the front cover is a stock photo so perhaps it´s not an "offshore sailboat" pictured, ( but a messy skipper in a sailboat (O:

 

Yes good point
