Towing

Hi

I need to tow a 21ft Speed boat in my 3.6m SIB

The Sib has a Johnson 2 stoke 1999 15hp engine on it.

The SIB is PVC.

Do you think I should glue on some D-Rings at the back of each tube and attach the speed boat to those?

Thanks

How far are you planning to tow it?
What fixings do you have?

Without knowing all the details, my gut reaction would be eyebolts in the transom

  • The engine on the 21ft speed boat has failed.
  • The boat is located in a tidal river
  • I need to tow it about qtr or half mile closer to the mouth of the river so it can come out of the water
  • I would like something that in future I could use again if the need arises. Chances are it won't.

I have brought some patches as shown in the attachment. If you look at the picture you will see where I plan to attach them (Red squares)

I did think about the transform, but the load combined with the weight of my engine worries me.

Thanks

James

If that's all you want to do, I'd hold it by hand.

Yeh, your probably right. It's actually more like a mile looking at the map lol.
I thought it might be easier as I'll be in the sib and dad will be in the speed boat.

•The boat is located in a tidal river

Wait for the tide to go in the right direction and drift/paddle, use the sib as a safety boat.

Tie the speedboat side to side to the SIB. You want the back of the SIB to be about even or just forward of the back of the speedboat.

Go slow, and test out steering before you need to be accurate about placement - you may need to alternate forward and reverse power to get the speedboat to go where you want. Make sure you have someone on board the speedboat with a boat pole to fend off whatever you don't want to hit.

Towing in tandem is fine for open water, but you can't really steer worth a damn.

Some eye bolts on the transom are very handy things to have. I’d much rather tow with them than patches on tubes. Jky talks sense about an alongside tow. A mile is quite far for that but if you take your time you will get there. Keep your engine completely astern of the broken down boat or you will get no steerage. Going with the tide and wind would obviously help reduce the effort involved too.

If it is a one off, you could try just physically holding it alongside (just with ropes) in calm conditions. I’d rather have some springs though – something like this:
