Technically, that was what is known as a trip and stuff - launched up in the air caught the stern on the next wave which flicked the stern up and finally went in nose first - did it in Scotland in a Phantom 18 (I was the navigator) and it happens so fast that you're wet before you have time to think.
The photo published by ADS is a pitchpole by the way!
I have never seen a RIB pitchpole as per the yacht example - IMHO it is impossible as it is the sailpower that induces that - and to trip and stuff a RIB you would need to be travelling 60mph at the very least - probably over 70mph.
Even given that you didn't mean pitchpoling you meant stuffing - it wouldn't happen in a regular leisure boat, and the weight needs to be towards the stern to "balance" the boat for top speed that many people are obsessed by - hence the need for trim tabs or bow tanks for rough weather use. If you have the weight too far forwards on any planing boat it will reduce its top speed considerably and increase the chance of burying the nose in a following sea - which just goes to prove everything is a compromise!
