it's not a bad crack as they go It's not structural as such and can be easily fixed. Water ingress into the ply of the transom is your only real problem. that will be worse at the transom cutout tham anywhere else.

I'd be getting a 10 or 12 mm Spade or Forstner bit or a hole saw and drilling a couple of test holes in 10mm incremeneither side of the motor on the transom. If the sawdust is coming out nice and dry then that's lucky for you if it's soggy then go down another 10 mm and so on at least this gives you an idea of the scale of the problem.. I guess it's best to wait till after your communications with seller and manufacturer have ended, but I don't think it's goinfg to be too tricky to fix. the Ali cappinf idea is a good one i think By the way

Basically all my RIB's have had transom problems, i believe it is an oversight by all rib designers and manufacturers, although some say it's the way i drive 'em.

All have been easily repaired, and with no long term adverse effects. This has also always been inexpensive.

Yours is easily repaired, so donít worry too much. It will, however, be an inconvenience.

For a boat builder, this is just a routine job - a bit like a hernia operation, frightening for patient, but routine for surgeon.

Dorian/Jason/Charlie...Mark et al.
What is your view? Can you share it with other RC owners. Do we all have something to worry about?

If its a 2005 build and only used for leisure purposes then surelly the hull is guaranteed for 5 years from manufacture.

I dont know where you guys are coming from, Rogue, et al, , thats a structural defect in my book.... any day of the week ! A 6.5 with a 150 on the back is not overstressed by any margin.

Has the original owner reversed and caught the o/b leg on something underwater though ? might not be the boats fault, and knowing the maker, I doubt it,.. but I wouldn't be going to sea in it, thats for sure, as its very hard to tell the extent of the damage without a full strip down of the back end ,which is a serious work shop job .. dont ask me how I know

we must read different books then!

if the crack went from top to bottom i'd be very concerned, but I see that sort of crack as easy to fix and make stronger

If he can ge recourse from the manufacturer or vendor then right enough but if not and it's down to him to fix I think it's important that he doesn'y get tucked up by the boat repairer. Perish the thought

I dont think our books are that different, since in my case the crack was from top to bottom, its just that you cant really tell without pulling it apart unfortunately

Tapping round about the stiffening knees should highlight some 'boss' areas if this is the case. I note that from the pics, the delamination is to the rear of the transom, where mine was to the front, however from quaoar's photographs it looks like all the damage is to the starboard side due to the effect of the engine offset .. which was exactly the same as mine, and suggests engine overloading of some kind or structural support weakness

*edit* At least the manufacturer has made some sort of representation already though

I have already received a message from someone at Ribcraft. If I had only been located in England I think this could be easily solved. I appreciate the fast response from them

Bigmuz7, the damage seem to cross the entire transom. The last image, is from the left side of the transom. You can see some tiny holes there, in the paint. I do not believe, not that I have much knowledge, that this problem is directly related to the engine. From what specifications I have got, the boat is rated for 125-225 HP engines. Original propeller is included with the addition of a steel propeller. If it was a damage from reversing into something, I think the engine or the propeller would show some damage.

A representative from a company building and repairing boats in Norway is coming over today to take a look at the boat. Paying him for an hour or two is worth the price I think. Hopefully he can give me some more information (and a price for the repair...).


Many thanks for the replies. I have to admit that I was quite shocked when I first saw the crack, and not sure what to do at first. Now things are moving forward.


And a final note...
The seller denies any knowledge of that crack...
So a lesson to be learned - always take a close look at the boat in person before buying second hand, and do it thoroughly

I had some cracks in exactly the same places as yours, turns out that all it was, was the fibreglass coming away from the wooden transom core where the builder (BWM) didn't wrap over the top bonding the two sides together.

Gel coat is a very Hard coating and as such will flex a little but more often than not will crack due to it's hardness. So not always a terribly bad thing.

You are doing the right thing however by getting a professional to look at it. Grinding the top fibreglass back will reveal all they will want to know about the underside.
