We had a houseboat on the broadwater last May.We were off North Straddie when another houseboat pulled up next door,like 15 feet away and were gonna stop there.Fortunately son in law is 6'8'' built like a brick one.When they saw him they moved off, about 100m but all afternoon and night there was a constant stream of cans and stubbies floating past,collected by us or a boat further down.We rang their boat hire mob,about the litter and the noise they said thanks but little they could do.
