Hi,
It could be some sort of grockel boat - the white upright pole/pipe with a bit of wood at the top with a cable running through it looks way more like some kind of an awning than actual ship's tackle.
To be honest, I'm not sure how any town can be ruled out as the background - there is very little to see. And even as a Sarfend girl, I couldn't rule out my hometown from that little bit of coastline.

(Or has the photo been cropped?)
I know nothing about Freemasons. If they were Freemasons on a jolly together, wouldn't they perhaps all have some sort of identifying item, such as a badge or a scarf or something? Or would they be incognito?

Lovely photo, by the way.
