I tend to drive the Blue Marlin on as well (in a marina - no rips or anything), although by the time the graunching noise started on saturday, it was too late.

I'm beginning to think that maybe the rollers are too loose and can flip over - and I should do them up tight in position while I've got the RIB on the trailer. Also, I don't think it's practical to get almost 2 tonnes of RIB out of the water without getting the bearings wet - I'll just make sure that I pack them with grease and service it regularly. When completely out of the water, on the flat, she's heavy enough that I can't move her backwards or forwards on the rollers. I have to winch her along and back again.

My biggest fear isn't scraping the transom as she comes off - but the outdrive leg. It hangs well below the transom bottom even when cranked up to the trailer position.

In future, I think I'm going to go for the innundation approach, and submerge the trailer and allow the water to take some of the weight of the boat as she comes up on to the rollers. At least that way the chines should ride up on the rollers rather than digging in and damaging the hull.

The trailer is the standard trailer supplied with the boat, so I suspect think it's mostly down to operator error and lack of experience.

I actually do normally drive on but lately I've been winching on it's definitely kinder to the trailer. It also is a definite advatage if you are recovering on a rope cos the boat likes to push the trailer along the slipway

No, I'm recommending that anyone considering launching in this manner looks at Dave's web site as a first step - hence posting the link. I posted it a second time as a literal answer to Nasher's question "Where do we sign up for the course" as I'm sure that Dave Mallett would be happy to combine the dem into one of his courses.

is it something you regularly do with Blue Ice?
I wouldn't even consider this with Blue Ice, as you know

Richard relax, Jono and I will take good care of Blue Ice and you can view the pictures afterwards. I can arrange for Rogue Wave to be on standby to ensure nothing gets broken

It's the Mallet method, Dave Mallet. Dave Mallet from Blackpool. Dave Mallet who runs Wavelength training. It's the Dave Mallet who's not Dave Manning.
Dave Mallet who drives a Humber.

Having said that, I do drive the rib on like that sometimes. Dave Mallet showed me how to do it.

If memory serves me well (which isn't it's normal performance!) our discussion was based on a statement made by you that anybody should be able to do it on any slipway or something like that anyway!

Believe me I would like nothing more than never to buy another set of trailer bearings!
Hi RW
Not one to take offense & agree that it dose not work for all slips & trailers!
Just happens to work for me.
Look for would to meeting you one of these days!
Nick or should I say Nock

There is a big difference between a 6m and a 7.8m RIB (and I don't mean 1.8m!!).

I'm not sure that you could recover a heavy 7.8m RIB in the way that the link shows - I wouldn't fancy trying/doing it anyway.
