Do Hippo's eat Swans?
I dont have much of a weed problem at my local pond its salt water, what is the problem is the expanding Swan population, nasty beggars chase me boats specialy if I sail too close to the young ones. Keeps the local youfs laughing saves them throwing stones.

We did have the pond emptied and cleaned out some time back cos of all the sh1t left by the wildlife (youfs and all), place stank like a teanagers bedroom

kept the holidaymakers away.
The one thing with sailing in salt water is corrosion, every sail is followed by striping down running gear and cleaning the only alternative is to annoy the maggot drowners which is a local sport for the youfs as well
