^^^ It was the latest thing once!

I have 2 kite leashes on my harness, one if for towing stuff that I find on the water. It is best to pick up and carry a twin tip, especially if it has a handle.
If it has no handle I will usually attach my spare kite leash to one footstrap and tow it in slowly, I recently did this with a 1.8M long race board in Jervis Bay, from about 1k out.
If I did not have the spare leash that bard was most likely lost, mind you if I did not have the 15M C4 and a Stella 1.46/46 it was also lost!

The way to tow something in is to keep the speed down, just planing is all it needs.
