Down by the head

A quick glance at the waterline around the bow will tell the informed observer how much fish any boat has at the end of a trip, hence the expression "down by the head". The small white area is the major indicator - on a big trip the CKS would see all of the 'moustache' under the water. Below are typical bows on a number of other netters in the port.
A rather untidy paint job seen here - with no fish on board having landed...
and the same here (well not the paint job which is much more tidy) - of course all hands in the port get to know the look of each vessel on an individual basis so can gauge the volume of the catch on a boat by boat basis...
on the Nova Spero, seen here with none of her usual fleet of nets and gear abaord, much tuna will be needed to put her bow down in the water...
and this boat will need a seriously big trip to hide the 'moustache'

there were a few big mackerel shoaling off the end of the quay this evening.
