Advice: Structural Problems?

[crazyhorse]

Well Mr DIY JW seems like you sorted another ribsters problems out,I see you got the old grinda out again.

Hows your own Mid engined Rib going?

Did you say were having a bit of a Knees up?

[jwalker]

Hi CH. You've forgotten one of our previous conversations. The engine is at the back. However, bloody slowly is the answer to your question. Everything which could get in the way has got in the way, including 3 weeks redoing the kitchen. Finished the second tank tonight. Got another one to make. My hols start on Friday so I'll be pished that night but it's to be a boating holiday with a difference this year, starting Saturday.
When's the Alloy one due?

JW.

I didn't say that you did, you did.
All I did was hit the quote button at the bottom of your post.

As for the personal jibe

Oh by the way your'e wrong.

[crazyhorse]

Thats the way I also read it Powerboat.

A little bit of a generalisation I think,if we are going to be fair about it.

Maybe down to the exitment of the night Eh?

Seems you got loads of boats,Have you Got any funny charter stories for us?

[Jonny Fuller]

I woudn't want it fixed, I'd want a new boat!
Once it's been cut, ground, and generaly messed about with, it's not the same boat anymore.
It should clearly have had knees in the begining, preferably from near the top of the transom down to, and tying into the longitudinals,(assuming it has any) with the floor fitted 'around' the sructure, not relying only on the floor 'as' the structure!

Morning all,

The RIB is rated to 60HP and although my current engine didn't come with the RIB, 60HP 2/ previously, my current engine is sold with the boat as a standard package on their pricelist.

The manufacture has been very helpfull in the past with other little problems - just hoping they are with this one.

Cheers
Daniel

I was talking about your problem to some mates of mine who are building RIBs (not in the country) and they have the same opinion as Jon Fuller actually.
They said that once the deck is cut it will not be the same original boat again. This should be your VERY LAST resort.
Is their opinion as well as mine that you should ask an expert who is building RIBs and once they look at your boat they will be able to tell you what is ACTUALLY WRONG with it and give you PROPER advise as to what to do next.

With all due respect to all, I think that the majority of people here (except from VERY FEW) are not experts on building RIBs or anything much really and whatever advise you get needs 3ple verification (trust been there, done that and unfortunately got the T-shirt ) but have learned my lesson.

Now would I get into trouble again??

Hi Kitten ,

I made an estimated guess that you weren't too sensitive !!!!

Nice website by the way !

Best wishes,

Stuart

Just here for the Craic (s)! as we say in Ireland !!!

[kitten]

Stuart,
Never been very sensitive or any other word beginning with sense for that matter.
If I was would I have that photo on the website? Trust me you'll know if I ever get the hump.

I just feel that there are too many myths and old wives tales surrounding boat building and in particular repairs, spread mainly by people who have obviously never seen it done right. If the fix is done correctly it may be better than the original, if not it may well be worse.

Things like Jwalkers trick with the masonry nail. Good tip for areas not under too much stress but all those raised fibers and fractured resin will create a resin rich interface, depending on the resin used this may not be such a bad thing But if you are using a brittle resin, then it is a bad thing.

Fairing back the repair for a nice long way is good, but in woven roving once you cut the strands you’ve lost the strength so you also have to overlap, could you tell if there were rovings in a csm sandwich, and if so what sort? The list could go on.

(Jwalker I am not putting down what you say, just using it as an example)
This particular problem is not in need of a repair, it's a fault in need of a cure there is a difference.

Manos, If you get three different people to look at it you will probably get three different answers, all will be best guess because you won’t want them to cut it open to see the extent of the damage if they are not going to sort out the problem. Read any surveyors report and they will have a get out clause about destructive investigation.

JK how about section based on boat services, where members can praise good work and damn the cowboys?
Then people will have half a chance of knowing who they can trust, or who to avoid.

Well said Manos. And you would know a pratt when you saw one, wouldn't you?

Cheeky bug**r.

It's something on my list of future developments for the site. Not sure when it will see the light of day though . . .

In the meantime reports of good or bad service are welcome on the forum. Just make sure that any bad reports are strictly factual and not libellous! The great thing about the forums is that everyone has an automatic right of reply so it shouldn't be too much of a problem

[jwalker]

Kitten, that's ok. As you obviously realised, my reply was not intended to be a step be step guide to the fine detail involved.

I’m taking to the RIB to the manufacturers on Monday so they can have alook. They seem willing to solve the problem at the moment.

Will let you know the outcome of Mondays meeting.

Daniel

[Richard B]

That sounds positive... good luck.

Another interesting thread and varied comments.

Fact. ALL FIBREGLASS BOATS WILL DEVELOP STRESS CRACKS AT SOME TIME OF ITS LIFE.

FACT. THIS IS MORE COMMON ON OUTBOARD MOTORED BOATS BECAUSE OF THE CENTRE OF GRAVITY.

FACT. A BOAT THAT HAS BEEN REPAIRED BY A RESPECTABLE LAMINATER IS OFTEN BETTER THAN NEW BECAUSE HE RECTIFIES THE MANUFACTURS MISTAKES.

AND THE BIGGEST FACT ABOUT CRACKS IS.

There is a RIB going around called the "The Shrink" it is now in the ownership of the new man in charge of Clarence marina.
This boat was built in 1991 and was one of the first Big Ribs ever built. It has been places and done things that is hard to imagine.
It has been sunk on more occasions than I can remember washed up on the shore at Hayling Island. fallen off of trailors, hit things run aground and generaly had a very hard life.
It is covered in stress cracks but is as strucualy sound as the day it was built. Conclusion, buy a boat that has been built right in the first place. Alan P

HHHMMMNNNnnnnn!! The gospel according to Allan Priddy!
Personally I'm not religous, as I think it's all fiction!...I'll just stick wit my 'crackless' boat thanks!

[Alan Priddy]

Perhaps you should consider driving your boat a little harder and see what happens? I wonder what will give in first, the driver or the boat? Alan P
