Rib towing behind yacht !!!!

Folks. I am thinking of upgrading from my quicksilver 380hd sib to a proper (ish) rib.

We have a 40ft sailing boat of often tow the sib behind us.

Does anyone have any experience doing the same with a 4.5m ish rib?

This will be for short journeys in the solent.

Thanks

Jon

It'll tow ok but will knock a few knots off your speed.

Yeah .. It wont plane ! so it will be a real drag ... pardon the pun .... last time I did it with a 5.8m it nearly snapped the line onto the bow of the RIB pulling a hull like that faster than a drift takes a whole lot of effort which the yacht will do, .. but after a while you'll wish you'd left it at home or moored somewhere Stick with the SIB ... been there and got the T shirt

The solution is to buy a bigger sailing boat with big enough davits and deck space to store the 4.5M RIB on deck.

I'm very experianced in using these sort of tactics with Mrs Nasher to justify a purchase.

I don't see it being a massive problem, you'll have the engine tilted to reduce drag. You will use a little more diesel but probably nothing to get worried about.

I have towed a 4m rib with a 33 foot yacht and it wasn't a problem, next time your out why don't you borrow a rib and try it out.

Its when he's sailing he'll notice the biggest difference.

We used to tow a 5m rib, and a 4m sib with a 54 foot ketch. (at different times)

Issues with the rib:
Quite heavy (but didn't seem to affect speed too much)
Required a heavy duty tow line, high stretch nylon was the best.
Make sure the tow line is long enough, we had the rib surf in and strike the stern on a couple of occasions in a following sea!

Issues with the sib:
Hard to keep tight enough not to damage due to temp fluctuations.
Very high stress on tow points

Sometimes a drogue is useful when towing to stop the boat overtaking the yacht. Of course this adds a little more drag.

Thank you for all of the replies.

Your advice is well received and from my person experience with the SIB I can relate to a lot of what you are saying.

Utopia solution is to buy a 65' boat with Davits. Whilst the wife agrees she isn't going to sign off 1m for the purchase just now !!!! :-(

I will make up bridle so the load if distributed from yacht and check that the D ring on stem of rib is secure / strong / re-enforce if necessary.

We are very unlikely to be towing in signicant following seas but I have tied a couple of fenders behind the sib in the past and this has helped.

I will let you know how we get on.

Thanks again

Jon

A 54ft Ketch would tow a tank through the water
