My BWM's got cracks all over the place, on the transom, on the chines even a couple up front. I too was a little worried untill I saw my bosses Honda 4 stroke racer, I'm surprised it still floats!

I wouldn't be too concerned if the hull was more than say 4 years old, but how much do you use her? If shes got some hours/miles on the clock you'd expect to have some cracking, wouldn't you?

Peeps are right to tell you to get in touch with the manufacturer, but get a second unbiast opinion from a reputable source first.

Ermm NO! Cracking is a good sign that the thing has not been put together properly in my opinion, especially as there are many boats that go to sea for a hard life and do not end up with these problems even after 5 or 10 years! Those cracks featured in the photos WILL lead to problems down the line if they are not sorted, as the boat is less than a year old it is still under warantee ffrom the builders, they will determine if the boat has been misused, most likely they will fix it as from the photos it looks like structural problems in the lay up. I have seen cracks appear in the same place on a variety of boats and in "my opinion, it always tends to be the cheaper brands" (not exclusively, but more often than not!).

That might well be true of boat construction these days with CAD and modern materials, but when ever more than one type of material is used to make a structure, and is bonded together there is potential for some form of stresses to build up, this is evident in older boat designs like my BWM, but its not falling apart is it! Yes I'd love a crack free hull, but unless I re-design it, it isn't gonna happen.

I bet there are many RIB owners on this forum that have started out or still have older RIB designs that have encountered some form hairline cracks that have formed over time, but RIBs are normally driven hard and having 130-250kgs or more of outboard stuck on the back and going into a F7 headwind is going to stress areas of the hull.

But don't say these RIBs are manufactured wrong......Its just that quality that is expected from a manufacturer has increased to such a level that it's the expected norm to have a RIB that is perfect! Even more so when you have to pay a small fortune to own a new RIB.

Erin, I hope you get your problems sorted by the manufacturer, I'm sure that they'll be only too pleased to help.

I would have thought cracks like this are quite common - gelcoat is a very rigid skin - hence brittle. It does not mean there is a problem with the laminate as such. Bit like putting hammerite over a plastic ruler - as soon as it flexes the paint falls off!!!

As people have said the main problem would be where the water gets to once the outer skin is broken.

I would have to disagree with that, most fibreglass structures flex and Gel coat is designed with integral elasticity which takes this into account. (to a certain point of course).

Yeah anyway, the fact of the matter is that this shouldn't happen on a boat that is so new unless it's had a right bashing, If it was my boat the main concern for me would not be the damage and who's going to repair it but rather what the boats going to look like in 5 years time with the problem continually reocuring , especially if the boat is used for what it was made for i.e bouncing around on the sea.

Thanks for the tremendous response. I was pleasantly surprised to find that Prosport have taken the initiative and have sent me an email before I've even had a chance to contact them about it

So the question now is..... how should it be repaired?

I would first go to Prosport and see what they offer you. I guess they'll want to help in the interests of customer satisfaction, it's only when communications between customer and Manufacturer break down you'll want to take things further. This is where the consulation of an indipendant marine engineer comes into its own, or just a dealer that you trust.

Go and see what they offer, you might be pleasantly surprised, they obviously have someone reading this thread for them to find out your having problems and for them to contact you first, this is a very good sign.

This statement is quite correct......For a newish boat. But don't you think that Gel coat gets harder and brittle with time? This is usually when these hairline cracks/crazing appear.

Jason's offered to come and collect the boat, so I will let him take a look at it and see what he proposes.

Thanks hightower
