Rope sizes

[stefan_r]

I want to replace the mooring warps on my 46', 20ish ton motorboat as they are getting worn.

I have a feeling that my existing lines are a bit overspecced....what's the forum's recommendations?? - a lot of the sites I have seen (Jimmy Green etc) only seem to be talking sailing boats that I would assume are lighter??

Also what lengths do you recommend for reasonable cruising and [potentially] rafting up?? for a full set of docklines.

Don't really fancy kevlar lines but any suggestions as to material or a decent hardwearing brand....need as light a rope as possible as her indoors does all the throwing!!!!!

Cheers

Not Kevlar.

Kevalr has no stretch to it, thats why rag and stick types use it for halyards.

I reckon you'd want about 18 mm, nylon or polyester, 3 strand is nice and stretchy for warps, octoplait is nicer but more £££s.

Mooring lines about 1.5 times the length of the boat.

......girls, girls, get back, please, one at a time......

I have the same problem with my SWMBO in that she constantly moans about handling rough ropes. For mooring lines I think you need something flexible but hard wearing. Nylon ropes tend to be quite flexible and smoother to handle but I've found they dont wear as well as a polyester rope. On my boat I have 2 multiplait nylon mooring lines bow and stern for SWMBO's mitts and 2 longer polyester lines which are used as shore lines and therefore used much less.
Personally, I like to be able to double lines back on board so that they can be slipped from the boat rather than the shore so I reckon your bow and stern lines want to be at least the length of your boat, say 50' in your case. Obviously, you also need a couple of additional spare ropes for springs but these can be shorter. For the shore lines, again I like to be able to double them back to the boat (especially useful when moored to piles) so mine are about 80' each and SWMBO moans about coiling those as they are heavy. These shore lines are also just about long enough to serve as a towing rope as well. Diameter-wise, I think you're looking at about 18-20mm for your boat but it will depend on the breaking strain of the particular rope you choose and that can vary a lot

I have the same trouble. With SWMBO moaning about carrying big coils of supper thick rope about. Thinking of getting some thinner stuff for overnight and short stops. You just cant get the crew anymore!!

Thats why we take our kids - they think its great to be in charge of the rope.
