Bump & Grind

Well!!! What can I say...

Went to test the BWM Rib I was interested in down Lee-on-Solent this morning.

The owner was backing the RIB and trailer down the slipway to launch when the winch gave way and the RIB slid off and landed the stern hard onto the concrete from about 300mm drop. We then winched the RIB back onto the trailer, backing the car at the same time as to minimise the damage.

Looking at the damage it looks superficial, chips in gel-coat through to glass fibre in places and limited along the edge.

Two questions. Does anybody think the shock will cause structural damage unseen with the naked eye? Judging from the photo enclosed do you think it is just Gel-coat damage?

The test went really well except the launch and got an hour blasting up and down the Solent.

A similar thing happened to me last summer when I launched our club Delta. The winch rachet broke and the boat came off the trailer and made its way down the slipway to the water on its own. Only damage was superficial like yours and we haven't had any other structural related problems since, and the boat is used at least once a week.

The damage is most likely contained in that area - I would get the repairs done before using the boat again to prevent any water getting under the gelcoat which is not the best thing!

Looks like a good cause for a reduction in the asking price .

Seriously though, how many of us use a secondary means of securing the rib to the trailer when launching? I do now after having seen two almost brand new boats try and launch themselves before the owner was ready

It's also amazing at the number of people who actually tow their boats on the road with just the winch strap attached

It may add some extra work during the launch, but I always leave a seperate rope from the boat to the trailer.

I detatch it only when the boat is in the water. I also use it after recovery just in case the winch strap breaks when pulling up the slipway.

If the mooring eye on the Rib gave out then I would stuffed too!!

The guy selling the RIB said that he'd get a new winch and have the repairs done, I suggested that I could re-negotiate the price and have the work done myself.

My concern is really that I've limited experience with RIB's and am worried that there might be a bigger picture lurking under the chips.

I guess that the corner between where the bottom of the hull meets the transom is the strongest part of a boat, isn't it??

Only you know how hard the boat fell onto the slip. Think of the weight involved and then think again about the possible consequences. There may be another BMW around the corner or then again if you buy from a dealer there is some come-back if the thing splits or leaks in the short term. But if this one does become yours, what will you do when it leaks or the crack in the gel coat gets bigger? Find a friendly expert from a dealership, pay him for his advice and take him with you. The guy selling this one only wants to get it sold so think very carefully. At the end of the day the decision is yours...and you will have to live with it!

I agree with Red Fox concerning "only you know how hard it hit the deck" but strictly IMHO it'll not be too serious. Get a discount and have it fixed or do it yourself with some gelcoat filler if confindent.

It looks ok to me and don't forget they get some Hard bangs out in the water. It definitely means a price reduction, I'd be looking at 30 Kwid for the winch and 200 for the gelcoat.

If you need tjhe number of a good surveyor who is in to ribs then send me a PM
I need a little bit of Rhythym and a little bit of Blues

One good thing though hightower you now know how important it is to secure your boat to the trailer and not untie it until its ready to be launched, agree it takes a few moments longer on the slip way but think about the cost in agravation :-) personally i tie mine to the trailer and i've seen other people with a chain clipped onto the bow mooring eye which works just as good.
As for the damaged BWM, have to agree with everyone else that its really up to you as you know how hard it hit the ramp and what the extent of the damage really was, dont be afraid of repairing the gel coat as its easy and if he's willing to come down on the price some what you may have a better bargain than you thought.
