A query.. what did John Goode do to justify having his name put on Portland Plotters? .. never seen that before...

[Sandero]

O use a device which is a two armed affair with a rotating lockable protractor/rule. I mount it with two drop in clevis pins. Like a parallel drafting arm. You rotate and lock the compass rose after registering it to the chart below...

Weems & Plath Chartkit Plotter

weems and plathe....

don't use it anymore... lives inside the nav desk waiting.

No longer sold.... it's retro!

He wrote the article about using them in the May 1997 edition of Yachting Today which included a branded one as a freebie with the magazine. It had both the magazine name and his name on it. (They are very lightweight, bendy plastic)

Hmmmmmmmmmmmmm

Who the hell does this mark guy think he is?! We can't all sail around with gold plated paper charts direct from the admiralty!

This video will explain why and you will never go back

Woh. I am 100% sold.

I love this guy too. Sylvia is an old Cape Cod name and his accent is a dead giveaway. He's a ringer for the Steamship Authority on the Vineyard.

Good google work there - as always - but that *Sailing Today* plotter is an El Cheapo knockoff....

How did his name get onto the ridgeedij plotter in the photo that I linked to?... small print lower left...

I also have one of those Portland Squares aka a Monkton Protractor which was a PBO freebie in the 1980's ( similar to this one ) Seashop - Portland plotter square LG.125mm

Mags used to give out good freebies.... don't get that on the internet

I can't make out what the wording is before his name on that plotter. Can you tell us what it says?

Looks to me like 'tide system devised by John Goode' which sounds like a bit of a stretch to me.... you didn't need to be billy the Boy genius to see that it could be used to do tide vector thingos....
