Now, I realise this is a big no-no as far as the RYA are concerned, but it's a technique that I've actually used quite a lot.
I understand the RYA are saying it's dangerous, yet in this article RNLI RIB training - Paul Glatzel
it's clear that the RNLI still use it as a technique.
The boats that I have paced, have all been roughly the same size (within a metre), and we've never had any problems.
Can somebody explain to me, exactly what the danger is... in a bit more detail than "the boat will get sucked around/under". I would like to understand exactly what the two boats will be doing and how they effect each other to create problems.
