Optimum Dinghy Painter

I've got replace the painter on my dink as the result of a night dinghy cruise where the painter got into the prop (don't ask).

What does anybody think about the optimal type of rope for this? Regular braided polyester like a sheet?

Nylon octoplait?

What do you guys use?

My dink is an 11" Avon RIB with 25 horsepower. I was thinking about 10mm nylon octoplait for stretch. On the other hand, chafe . . .

We only use polypro, because it floats! The standard 3-strand degrades quickly in sunlight. We have a towing bridle made from New England Rope's dual braid - polypro core with a nylon cover. It's 7/16", strong, and it floats.

However, we don't tow very often, so usually we just use a lightweight painter made of Regatta-lite, a 12-plait polypro.

Thanks. I looked at polypropelyne, but since I never tow my dinghy, I didn't think it was a good trade off to get floating in exchange for UV degradation.

Nylon = good for stretch but bad for chafe

Polyster braid on braid = no stretch but better chafe resistance

That's what I'm looking at so far. Unless someone has some other argument for polypropylene

Use floating line ... that means it doesn't get among your prop ... but you have already learnt that lesson ...

I tow an 8ft grp dinghy and have learnt several lessons the hard way ...

1. Use floating line
2. Tow the dinghy with 2 lines ... regardless of whether or not you rig a bridle ... use 2 towing lines
3. Use L O N G towing lines when sailing or motoring downwind or when there is a following sea ... long towing lines keep the dinghy in the next trough behind meaning the dinghy doesn't surf downwave & ram your transome
4. Do not leave gear in or attached to the dinghy whilst under tow ... outboard, bailer, oarlocks & fuel container have all mysteriously vanished at one point or another
5. Beware dinghy filling up with water when it rains
6. Employ effective anti-chafe measures for both towing lines & check frequently for signs of chafe

The NE Ropes' dinghy tow line has a nylon cover, so the polypro isn't exposed to UV. The other polypro ropes are cheap, so you can afford to replace them.

I don't, however, tow at all. I have electric davits. I just need a painter.

Nylon 3 strand, dirt cheap, takes splices nicely.

Are you seriously that worried about chafe? You can always replace it when one strand finally gives.

Probably not. I would be more worried about UV since I leave the painter tied to one davit. Thanks for that; I just ordered some nylon. But octoplait which is nicer to handle than 3 strand.

Octoplait splicing is a bit more involved, but looks nice.

This is what we use both for towing and for stern tieing.

I use 5/8" poly for my dinghy painter as well. It's not as strong as 3-strand, nor does it seem to handle UV as well, but it floats. I'd never consider towing with it as I don't think it has the durability. And I change my painter yearly, using the replaced one as a spare or for other purposes.
