Our Catalina 36 came with a very rusty danforth anchor. So it’s time to upgrade to a rocna 15 bought on defender.

As soon as the rocna 15 showed up, it was my surprise to realize how big it is. After a lot of research let’s upgrade the bow roller!

Hardware requirement

Equipment requirements

I decided to get the bow roller from catalina direct few other options who could have been a good fit:

Tools requirements

  • Grinder: https://www.amazon.com/gp/product/B00U24VG0W ($99)
  • Sawzaw: https://www.amazon.com/gp/product/B00ODN1CP2 ($85)
  • 15mm wrenches (x2)

Remove legacy bow roller starboard bolt

Not easy to remove (suprised? :)), it looks it has been there for a very long time. Used 2 x 15mm wrenches to get through it.

Cut off the vertical part of the original anchor roller

  • carbide tipped sawzaw blades (x2):
    • https://www.amazon.com/gp/product/B01MQWFQBV ($24 for 2 of them, I needed both)
    • I have been using the 6″, but I have the feeling, it would have been better with a 4″ blade, maybe it would have saved me one blade.
  • grinding wheel
    • https://www.amazon.com/gp/product/B00004RH8I ($7)
    • use to make prettier the rough work generated by the reciprocating saw

Position the anchor roller to find the good fit
