I agree it's completely about trade, but that's almost synonymous with influence or control. Not an embargo or blockade but certainly a prohibition. Which is plenty annoying in its own right (though lost revenue matters more).

If you want to calculate this using retail prices, you're going to have to work out how much space a ton of raw wool takes up in a cargo hold. A tun of steel will weigh far more than a tun of styrofoam, but take up the same amount of space.

For a single tun lot, the maximum lot value would be 600d. See Maritime Trade 2.

Granted, the system presented in Pilots' Almanac is basic, and not designed to do what you are trying to do.
The following guidelines provide a basic system for maritime trade from the point of view of the captain of a trading vessel. How to make deals and buy/sell cargoes are discussed in sufficient detail for most players. Those who want to immerse themselves in the minutae of international trade from a mercantyler's point of view, will, alas, have to await a planned trade and economic module.

Found on Wikipedia

Tun (unit)
The tun is an English unit of liquid volume (not weight), used for measuring wine, oil or honey. Typically a large vat or vessel, most often holding 252 wine gallons, but occasionally other sizes (e.g. 256, 240 and 208 gallons) were also used.

Tonnage
Not to be confused with Ton.
Tonnage is a measure of the cargo-carrying capacity of a ship. The term derives from the taxation paid on tuns or casks of wine, and was later used in reference to the weight of a ship's cargo. In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship. Tonnage should not be confused with displacement, which refers to the actual weight of the vessel

Ton
Not to be confused with Tonnage or Tonne.
The ton is a unit of measure. It has a long history and has acquired a number of meanings and uses over the years. It is used principally as a unit of mass. Its original use as a measurement of volume has continued in the capacity of cargo ships and in terms such as the freight ton.

It is derived from the tun, the term applied to a cask of the largest size. This could contain a volume between 210 and 256 US gal, which could weigh around 2,000 pounds and occupy some 60 cubic feet of space.


Tun Barrel with Wine
Wine & Barrel, 240 gal = 2400 lbs (10 lbs per gal)
Wine weight, 240 gal x 8.47 = 2032 lbs (8.47 = 1 gal liquid)
Barrel weight, 2400 - 2032 = 368 lbs

Tun of Flour / Dry Goods
Flour : 240 gal x 5 = 1200 lbs (1 gal of flour = 5 lbs)
Tun Barrel with Flour : 368 +1200 =1568 lbs

I think the barrel weight is too high. Does anyone know what the weight of an empty tun barrel is?

Update on the weight of barrels

Barrels with Liquid
------------Liquid gal---Liquid lbs----Empty lbs----Full lbs
-----------------(Lg)-----------(Ll)--------------(El)---
-------------------------------Lg x 8.34-----Ll x .046------Ll + El----H x W---
Tun-----------240------------2001------------388------------2389----42"x 42"
Hogshead-----60-------------504--------------98-------------602
Barrel----------30------------250--------------49-------------299
Keg-------------15------------125--------------24-------------149
Sm Keg---------5--------------42---------------8---------------50


Flour / Dry Goods
Flour : 240 gal x 5 = 1200 lbs (1 gal of flour = 5 lbs)
