Unknown vessel = SILVERBECK

Silverpoint or Silverbeck. Bartram vessel. Not an awful lot between them

Correct SILVERBECK.
Gp

Hi Tanker. i'd be interested to know how you came to favour of Silverbeck? I'm finding it hard to tell them apart from the 2 photos on Woody's site

I have a shot of her by Silver Line in 60s. in an old shipbook.
Gp

probably the easiest way of seperating them is that SILVERPOINT has a much larger forward masthouse than SILVERBECK

Ah! yes. And Silverbeck has no masthouse around the kingposts. I never was any good at spot the difference. Anyway thanks that removes ALL doubt. Silverbeck it must be.
