John, I don't think anyone wants to correct you, just guide in the right direction with all good intentions, take your above line for instance you mention total tonnage as gross, whereas if you want to be technically correct then total tonnage is 'Displacement tonnage' which I think has already been mentioned.
As observed earlier there are minimum 22 pages in sequence in Business and Law for the Shipmaster devoted to tonnage, plus other references, then there is further information in 'Chartering and Shipping Terms' which covers other aspects, not to mention 'Handy Guide to Stowage' which covers other aspects of tonnage applied by different countries, it is a minefield for legal and carriage/dues/Customs purposes and it is not something to be learnt in five minutes.
Because people quote Gross and Nett tonnages for Canal passages, there are other things such as 'exempted spaces' which vary from vessel to vessel which have to be taken into consideration when quoting Gross or Nett.
See what you've started Frank!

Re: Tonnage
#20 Doesnt work like that John. Ships and canal authoritys have different agreements as to exempt spaces. A post many moons ago was on Suez canal
exempt spaces and why the forecastle head was cleared out. You would have to have the certificates for such in front of you to understand what were
tolled on and what werent. Would imagine the Panama Canal when it was under US control the old Bale of cotton rule would also be there somewhere.
Way above my head to commit on. JS
See Ivan remembers his shipmasters business. To hire the marine law volume when I started on a correspondence course in 1964 Ivan was 30 pounds for the year and imagine the amount of pages that had. I didn’t want to be a lawyer , so decided to stay at sea and forget the grandeur bits. There were enough sea lawyers as it was on ships. Cheers JS

Re: Tonnage
Even in the world of motorcycles some manufacturers state the weight of model A as dry kerb weight (no oil or fuel ) Honda seem to quote Dry Kerb weight. Where as Yamaha quote wet weight(Oil & Fuel). To me Yamaha are being honest as at least you do not have think about how heavy a bike is. Where as Honda are not being as forth coming as they should be. This was my last bike a 900 Yamaha Tracer 213kg without luggage, with Empty panniers 227 kgs and if panniers are loaded as per weight allowance you are looking at 250kg. May not sound a lot but trying to get the bike upright from the side stand takes some effort.Tracer 1.jpgtracer 2.jpg

Re: Tonnage
John, Ivan, thanks for that.
As a mere catering seaman I only know what I have heard about such things.
I am greatfull that you take the time to enlighten me about such matters.
We can only learn if we are told and believe me when I say you are two of the best educators on site.
Long may you continue.
Happy daze John in Oz.

John it took a steward to teach me that a side plate was the correct term for what I had always called a tea plate. JS

Ain't that the truth! During and shortly after the war having lost our home three times during it we had a motley collection of cutlery and imagine a 16 year old from such era entering the saloon in his ill fitting uniform (you'll grow into it!) and seeing more cutlery laid out on one four setting table than in all the cutlery drawers at home, which one do you use first, luckily mother had taught me the basic rule start on the outside and work inwards. The sea was a learning curve for many in all departments, the benefit being Sunday dinner every day and Christmas dinner once a week, and just to keep in theme with the title, it was a 'ton' of food compared to shore rations.

Re: Tonnage
When you think you have 'Tonnage' sorted out, try 'standards' of timber. Every exporting country has its own standard
