- After any grounding it really is very important to check the internal and external condition of the vessels structure. In this serious failure of the vessels internal matrix that supports the keel if after a grounding you see this sort of damage... do not under any circumstances sail the craft. Seek professional advice and I do hope you have good marine insurance. I travel in many directions around the world to look and advise on this sort of significant hull damage to individuals, boat yards and primarily insurance companies.
Very nice video. It would be interesting to see how a repair like this is done. How do you maintain the alignment and geometry of the boat when you start to cut it, I wonder.
One of the great things about your videos is that they are short and clear. Very informative this one as well. Thanks!
Thanks really appreciate your comments 👍
Appreciate your video clips Ben. Surveying in the southern Caribbean at the moment.....!
I can think of worst places to be!!
These videos are great. Thank you!
Glad you like them! Thankyou
Another interesting day at the ‘office’ again! Quit a destruction indeed. Don’t think I would like to buy this yacht, even after an extensive repair. The corrosion on the keel bolts also were wuit extensive. Hopefully from standing water in the bilge.
Thnx again for s great video!

Many thanks for the comment. Once repaired, many are better and stronger than when first built... the but is as long as its been done properly. Thanks Harry 😊
so informative , thank you
Definitely a boat needing love and repair. Interestingly a surveyor did once comment to me that many US designed and built boats show the convex shape behind the aft edge of the keel, even when they aren’t damaged.
Always interesting, and just highlights whyits so important to have a survey. Cheers
Another fascinating example Ben. You just love making grown men cry don't you! 😂 Still refitting my Contest 33 and will (eventually) give you a call. Frankly, I wouldn't approach anyone else! Cheers, Steve Cottrell
Good to hear from you!! One day we will do something with Tom!!! Haha
@@TheMarineSurveyorNotebookBenSu That's a good idea - I'll put it to him. Maybe time to survey JB ! 😆
is there a specific make you find keel impact damage worse on?
Hi encapsulated keels normally are better.. then solid hull with bonded in frames then it's pretty much open to the level of impact. That said hulls that have a keel root created are often bit stronger than a flush fitted arrangement. Hope that helps
Thanks what’s obvious to you blinds my passion😹
This grounding happened years ago. In all probability it's had numerous incidents. Not worth repair. It's a chop up. The work to repair this properly is enormous. And it hasn't been maintained properly. No professional would touch it.
Interesting video. Is this economical to repair?
This is a good question, generally the beauty of GRP is almost everything is repairable.. its the point of where the value of the vessel sits. A good repair would certainly make her a stronger and stiffer hull if properly undertaken.
This is why a production-constructed yacht has to be lifted every time after a grounding. It looks to me that this one has a bodged repair.
Unfortunately the inner pan and outer hull laminate have separated, the two are put together with just paste. No simple way to rebond without cutting out the internal returns and grp pan...
Yep. That putty paste bond is quite weak. The MAIB say it is their biggest concern about yachts.
Do you think the keel has taken the weight of the boat to cause all that damage
The vessel has certainly had a good grounding at some point. The compression post and localised deck issues are also good indicators. Unfortunately, because the external and internal hulls have only been bonded together with just paste, from the forces applied its quite easily seperated. At that point the hull has lost most of its designed strength. The vessel has been supported ashore as best as possible to prevent further distress.
I do not like these type of double hull constructions, prefer to see laminated ribs and webs. But that's old-fashioned me...
I'm in the same club as you... mines a 40 year old sparkman and Stephens ketch...
What would you expect the repair of such a damage to cost? Do you think repairing such a damage can be lucrative or will the cost be much higher then the value of the boat?
The responsibility of undertaking the repair by someone who is competent is essential, if it was to fail someones life depends upon it being 100% right. Its not a quick way to make money..
I'd walk away.
This boat has been totally neglected, damage notwithstanding, every system must be disgusting and disintegrating.
If that is how the keel-bolts look, how does the engine compartment look? Or the chain locker? Or the mast-step, chainplates and stauntions.
No thanks.
Bolted on keels are a disaster waiting to happen.
Not always.. it all depends on the quality of structure!
