Moving anchor roller on a cat

Thinking of leading rode under tramp to the crossbar and deploying from underside. This should allow easier bridle attachment and avoid hull chafe when droping/weighing. Is anyone aware of a bow-roller designed to install under a crossbar? Or is that a custom fabrication.

i believe most bow rollers on cats are custom fabrication

btw : we are very happy with our chain above the tramp, for all sorts of reasons. ease of inspecting anchor swivel / shackle etc is one

cheers,

Likely a custom design and fabrication. If possible two rollers that will hold your anchor securely and high up out of the water. Shouldn’t be too expensive built in aluminium plate.

As pointed out earlier, if you intend to mount an A-frame or bow pole for a screecher, gennaker, asymmetric, etc and assuming you have an aluminium front beam, then the beam will need to be supported against compression from the A-frame/pole by at least a strut from your main beam. Turning the strut into a catwalk will provide several additional benefits.

Depending on the length of the run from the roller assembly to the windlass or cleat or whatever you have back at the main beam, you will need to support the rode to keep it from drooping. This will be particularly important for chain rode. If no catwalk this will be quite difficult.

We have a catwalk and the bow roller is built into and under the catwalk immediately behind our front beam. The chain goes on top of the catwalk and the anchor windlass is also located on the catwalk immediately in front of the main beam. Benefits are easy access to chain and anchor when up, clean front beam with no anchor or chain above, in front or under the beam, anchor rode can be seen through the trampolines from the helm, hard catwalk provides firm footed access to forestay and front beam, we store our passarelle on the catwalk, anchor is held high without interfering with sails or footing.

That’s old school, reinventing the wheel

I didn't know that. Thanks.
