If the OP goes down this route - make sure to get a locking carabiner. With the right forces on the rope, a carabiner can unclip itself

Nto over thinking it. Just want to get the right stuff. Am familiar with mooring a boat, knots etc, but never kitted a boat before as always used someone elses.

What is confusing is that on the web the strength (i.e. diamaeter) of rope is generally by length of boat, and I guess they mean a yacht. As a RIB is a lot lighter than a yacht, I guess you can go for thinner, less bulky rope.

So, what diameter rope for a 6.5m RIB?

My list so far for my 6.5m RIB is:

1off x 7m for Painter = 7m
2off x 7m for Springs = 14m
2off x 3.5m for Bow & Stern = 7m
2off x 15m for towing, quay walls etc. = 30m

Total length is 58m. So might as well get a 100m reel of Nylon and use the rest for anchor line and spare. Cheap at 57 from Mooring Ropes from Boat Gear Direct

Grateful for for the view on this approach on here. Ta.
Apologies if I came across rude when suggesting you were over thinking it.

I think that your numbers and lengths are good but think the line is too thin. Not strength wise but for ease of handling.

I would go a lot thicker for the painter and probably 14 or 16 mm for the mooring lines.

I would agree that you could use floating line for the anchor and it will make no real world difference.

Yes you can get much expensive ropes for particular purposes that will "perform" better but for general stuff like this, I don't see the point TBH.

Taking a full turn around the eye on the mooring buoy prevents the rope rubbing and cuts out a lot of the wear. For overnight stops on visitor moorings I've never felt the need for anything more sophisticated.

If you're leaving a boat long term on a swinging mooring it's obviously different. I'm not keen on carabiners or snap links for mooring though.

I saw someone do the same thing off of Brhyer on the Fived moorings....it's VERY fast flowing
and By morning the 3/4" Rope was half way worn through!
I'd rather not take the chance myself.

you must be a nervous sailor!

Some interesting points - I'll add a locking caribiner to my kit list. You could use a shackle but there is faff involved which means you won't do it.

The thought of my RIB floating away in a 4knt + Springer whilst moored overnight in Tresco sound .....and straight out into the Atlantic
(for the sake of a 20 shackle!) would make anyone with half a Brain a Tad nervous
Been there a few times now though
