-So you should specify your vessel capacity. Currently you must
-specify the actual mass and volume, as two numbers each with units.
-The system understands the units t (tonnes), kg, l and kl
-(kilolitres). There should be a space between the two limits, and no
-space before the unit.
+So you should specify your vessel capacity. You can enter things
+like:
+
+- sloop
+
- The capacity of a sloop, exactly
+
- 20t 13kl
+
- 20 tonnes (20,000kg), 13 kilolitres (13,000l)
+
- sloop - 100l 100kg
+
- The capacity of a sloop minus 100l, minus 100kg
+
- 2t plus 500kg minus 200kg
+
- 2300kg, with no limit on volume
+
+
+Formally, the capacity is a list of terms, all but the first preceded
+by one of -, minus, +,
+plus. Each term may specify a mass and/or a volume
+(separated by a space), as a number followed (without an intervening
+space) by a unit (t, kg, kl or
+l). The first term may be a ship name or abbrevation
+instead. If the first term specifies only one of mass or volume, all
+the subsequent terms may only adjust that same value.
