This is a specific conversation about Cat scratching posts — ones they'll actually use — ask about yours and get one honest answer for your exact situation.

Living on a sailboat with a cat is a specific kind of challenge — space is tight, everything needs to be stable when the boat moves, and you can't have anything that'll absorb moisture and rot or shed fibres into bilges. The most common reason cats ignore scratching posts is they're too short for a full stretch, too wobbly, or the wrong material — and on a boat those problems get worse fast. Before I point you in a direction: how big is your Russian Blue, does he or she tend to scratch vertically or horizontally, and what's currently taking the damage?
She's a medium-sized female, maybe 4kg. Definitely vertical — she goes for the companionway boards and the nav station edging. Sisal rope on a wooden post is what I've seen her use at friends' houses.

That's really useful. Sisal rope on a vertical post is exactly the right match for her. The companionway and nav station edging make complete sense — she wants a tall, firm surface she can really lean into. At 4kg she needs a post at least 60cm tall, ideally closer to 70cm, so she can get a full stretch. What's your main concern about posts on the boat — is it the base sliding around on a wet or moving deck, the post falling when you're heeled over, or something breaking down in the marine environment?
All three honestly. The base needs to grip a teak or fibreglass sole, it can't tip when we're doing 20 degrees of heel, and I don't want anything that'll go mouldy or rust. Budget is fine, I'd rather buy once.

Understood — buy once is the right call here. I'd go with the Vesper Cat Scratching Post by Zingz & Thingz, but let me be more specific about what actually works in your situation. The most practical option I'd point you to is the PetFusion 3-Sided Vertical Cat Scratching Post — it's 65cm tall, all-sisal, no carpet, no MDF core to swell with moisture, and the three-sided design means it's wider at the base than a standard round post. That wider footprint means it won't tip at 20 degrees of heel the way a skinny post will. You can also add a non-slip mat or bungee it lightly to a stanchion base when you're offshore. No metal parts to rust, no fabric to mould. It's available on Amazon UK and holds up well.
That three-sided design is smart for stability. Does the sisal hold up okay in a humid environment, or will it go rank?
inparticular.ai
Sisal handles humidity better than carpet by a long way — it's a natural fibre that breathes rather than trapping moisture against foam or MDF. In a boat environment it will eventually grey slightly and soften, but it won't go mouldy the way a carpet-covered post does. The main thing to avoid is a hollow cardboard core or an MDF base — the PetFusion uses a solid sisal-wrapped frame, so there's nothing inside to swell or delaminate. If you're doing long offshore passages and it gets properly drenched, let it air on deck rather than below and it'll dry out fine. For an 8-year-old cat who's already been living aboard, she'll take to it quickly once you put it where she's currently scratching.
Perfect. I'll order it. Should I do anything to encourage her to use it rather than the woodwork?
inparticular.ai
Yes — placement first, then scent. Put it right where she's currently scratching the companionway, not off to one side. Russian Blues are particular about where they scratch; they're not going to walk across the boat to use a post when the thing they like is right there. Once she's using it consistently, you can move it a few centimetres at a time. Rub a little dried valerian or silvervine on the sisal — not catnip, Russian Blues are often less responsive to it. And if she goes back to the woodwork in the first few days, don't punish her — just temporarily cover the boards with something smooth like tape-backed plastic sheet so they're less satisfying. She'll switch.
