Sea anglers, charter boat operators, potters and even commercial trawlers... these fishing marks are going to change the way you fish.

We are talking about "Trawl Hitches"

A trawl hitch is a geographic spot on the sea bed, where a commercial trawler's nets have "come fast". The nets have become entangled with an underwater obstruction. The results of this can be expensive, nets to be repaired, time lost at sea. It's not surprising then, that commercial trawler skippers keep their own databases of places they've come fast. So they can make sure they avoid costly damage in future. This data is generally jealously guarded for competitive reasons.

But now we have obtained masses of this data and are ready to publish it in the form of "Fishing Marks", overlaid on standard official charts, running in a Windows chart plotter system "SeaClear".

This will enable you to visit these spots and fish.

WHY ?

Because at these spots round fish congregate, and you can catch them ... find out more:

So... what's this all about ?

The data is derived from a number of vessels and represents years of survey work by commercial fisherman. This data contains uncharted wrecks, reefs and marks where trawlers have come fast on the bottom. These are marks that commercial trawlers avoid as their trawls get snagged and are areas that provided cover and habitat for round fish such as Cod, Haddock, Bass, Pollack, Ling, Whiting, Pout Whiting, Conger and Coalfish. A mark could be a small reef, outcrop of rock, sunken sea container, uncharted wreck, rough ground or some other object on the seabed.

"Whilst there is no guarantee that there are round fish on all of these marks, they do represent the most likely places where round fish can be found"

It is the case that fish will inhabit these marks for a few days and feed around the mark until the local food source is eaten and then the round fish will then move onto the next mark. A good echo sounder/fish finder will indicate if there are round fish on a mark.

It is important to understand that a number of marks may have be visited before fish is found, equally a mark may not have fish on it one day but does the next day as many of these species of fish move from one mark to another depending on the food supply.


Contrary to popular belief that round fish can be found in the lee of a mark this is generally not the case. Round fish swim into the tide and are generally just up tide of the mark when feeding. This is because of their in built survival instinct and the flow of oxygenated water through their gills. After all fish will reach the safety of a wreck or reef by swimming down tide quicker and with less energy expended than swimming up tide to reach safety.


Our database covers the whole of the English Channel from the Isles of Scilly to Dover and extends towards the French coast. We also have data for the north coast of Cornwall, Devon, and South Wales. We have published this data pre-overlaid onto electronic charts as a complete set of Fishing Charts, that will run in tandem with the "For Navigation" Charts for SeaClear DVD or USB.

Each fish icon represents a trawl hitch, notice how they seem to form groupings. These marks have been collected over many years by many sources, and they tend to arrange themeselves into identifiable clusters.




This data is first class data and is currently being used by commercial fisherman including some of the top earning trawlers. Most of the marks are two or more nautical miles from the coast and therefore a reasonable vessel is needed to fish these marks. Without this fishing data your chances of having a good day’s boat fishing are dramatically reduced and this data gives the angler a fighting chance of a good days fishing.

"Fishing Charts for SeaClear 2012" contains all the 400,000+ fishing marks we already have plotted, covering the geographic areas mentioned above... PLUS all the standard "For Nav" charts embedded in the product, covering all UK and Ireland.
