Archive: Testing of mobile cleaning tools on hulls of leisure boats

On the background of the contamination of surface waters with antifouling biocides, non-toxic fouling preventions techniques are in the focus of research activities. One option is the cleaning of the hull on hard, non-abrasive coatings which have to be cleaned by the boat owner on demand. LimnoMar finished a research project at the end of 2014 to identify reliable and suitable cleaning techniques for leisure boats. Actually, more than 70% of leisure boats in Germany are at berth in freshwater areas where cleaning is a more realistic alternative than in saltwater (See: http://www.limnomar.de/index.php?PHPSESSID=1dj80nbkifge3og8i91p10spb1&modul=gruppe&grp=2&pid=26 )

In the ongoing project the most promising cleaning techniques, the so called Big Easy cleaner and a modified bagywrinkle will serve as cleaning tools. Participating boat owners will test on their own the efficacy, suitability and handling in different freshwater regions:

Seglerverein Wakenitz, Ratzeburger See
Seglervereinigung Hüde, Dümmer
Vereinigung der Hanseaten im Yachthafen Hasenbüren, Bremen Unterweser
Bootscharter B. Rietz, Zeuthener See, Berlin

The non-toxic, hard, non-abrasive coating was developped by the German paint manufacturer Wohlert, Ritterhude, and placed at the boat owner disposal. The lower water authority of the Schleswig-Holstein is participating in the project regarding legislative aspects of the cleaning activities and the environmental risk of the removed fouling community released in to the water. Each of the respective water authorities are involved in the discussion on the waging of benefits and disadvantages of cleaning instead on use of antifouling biocidal products.

The duration of the project is one year.
