The Underwater Council of British Columbia, a Non Profit Society operating with Volunteers and funded by Donations, has been serving BC Recreational Divers since 1991.


Line Mussels Scraper Project

The line mussels scraper project was initiated by former UCBC Director Scott Mitten in 2013.

Upon his first dive on a UCBC Mooring Buoy Scott noted the incredible build-up of mussels on the mooring line and it's effect on the attitude of the buoy on the surface. If left unchecked, mussels can quickly accumulate and pull the mooring buoy under the surface.

The UCBC Mooring Buoys receive a high volume of use by recreational divers who very conveniently must make a three minute safety stop at 15 feet, exactly where the mussels grow thickest.

It was with this in mind that he designed and built the first prototype of the line scraper mussels remover. 

Mussel scraper on a new line

The scrapers are of a simple design: small sections of PVC pipe that are assembled on a new mooring line before it is installed in the water.

The pipe consists of a handle section extending at a right angle from the mooring line as well as beveled edges on the pipe that enclose the mooring line.


Divers can grasp the handles individually or as a team for pushing through extra thick growth. 

There are three line mussels scrapers installed
on each UCBC Mooring Buoy:

  • 1- Between the surface buoy and the lead weight that keeps the line underwater
  • 2- Between the lead weight and the mid-float
  • 3- Between the mid-float and the bottom connection


Please help us keep our Mooring Buoy Fleet clean and safe.

When diving one of the buoys pull each scraper down along the line on your descent and bring it up for another pass as you ascend. This method ensures that the scrapers are in position for the next group of divers to do their part as well.

If you notice a missing or broken line mussels scraper, This email address is being protected from spambots. You need JavaScript enabled to view it. so we can get it replaced ASAP! 

The UCBC is currently looking for groups such as Dive Clubs or individual divers to help with the maintenance of our Mooring Buoys with the Adopt-a-Mooring-Buoy Project.
