I have a VERY annoying very small leak thought the bathing ladder bolts...
unfortunately there is NO WAY to get to the back of the bolts from the stern to hold the nuts while undoing the bolts and the bolts and the nuts are loose a bit and all my tricks and tries has failed miserably so far to undo the bolts and reseal ... no idea why Jeanneau can mount this nuts without glue then to the hull and do not leave any way to access them - my only option left so far is to drill a holl in the hull to get access - but really do not like the idea...
any ideas will be greatly appreciated ...

That's truly a puzzle since the boarding ladder would be added pretty far along in the assembly process. It's a stretch in the 36i, but they can be reached.
Sorry.

at the stern my little Sun Liberty 34 has a lifeboat garage and the boarding ladder is behind it, I have no idea how someone can manged to get to the nuts and hold them while undo the bolts... with a inspection camera and more then a hour squeezing it through some holes you can get a look at them... but to get a wrench there is mission impossible  I guess if you have some special tool with about 5 angles have done this multiple times before you may be able to do something... |

Frustrating if you can't get at them can you cut a hole in the life raft locker to get at them. On my anchor locker jeanneau have a couple of holes cut with plastic lids siliconed in to get at the cleat nuts wondered if you could do similar in the life raft locker or a small inspection hatch cut into the deck but like you a bit of a last resort although probably the quickest. Hopefully you will have a eureka moment.

Hopefully you will have a eureka moment. That was my idea tpp to cut a small hole in the liferaft locker , it will not be visible and all is good, but the issue is how to seal it as it will be under water from time to time when sailing or at leadst very wet and I do not want to fix a marginal leak and open another one I cannot glass it as do not have acces from the back - the clossing lid should be very flat as the distance between the wall and liferaft is no more then 1/3 inch or less... e.g need to be something very low prifile , very watertight and very prone to failing ( e.g just a cap with sikaflex is not going to do the job) |

Understand about the plastic cap, if it a flat surface a 3mm stainless steel disc with counter sunk self tapers sealed with sika flex 292, could even stick bits of ply on the inside for the self tapers to get more grip. With a good overlap the sika flex will be a strong bond. Hopefully won't be coming of again or if it is go for the sikaflex 291.

Bolts even better just make sure nuts well glassed or your back to square one ............. |

Hi Vasco
Drill out the bolts.
Replace with RIVNUTS (like a BLIND rivet but you can remove the bolt as the nut is crimped underneath.)
Discovered them last year and they are great. [I've replaced some rivets and used rivnuts to fix spreaders, gooseneck, mast mainsail slider gates etc) Perfect for blind fixings where you can only work on one side of a panel/mast etc
They come in various diameter sizes. Stainless steel or aluminium.
Search on UTube for instructions and how to make your own DIY tool to save big money on a commercial tool. I prefer 6mm diameter with hex heads which can be removed over and over again.
Enjoy!

And indeed it works great but in Vasco's case he should dig it into the polyester not the teak because of the forces on the ladder . Fill the drilled hole with epoxy resin , squeeze/bash the (S/S) rivet nut in all the way and tighten it. Screw in a ( clean) bolt a few times to clear the excess of epoxy in the thread and when it has cured get a thread tapping bit through because of the hardened epoxy leftovers .After that sikaflex seals the top part . I sometimes need additional tapping also even when not using epoxy because of reasons of over-tightening the rivet nut . Great tool, I have often used it , much stronger than plain rivets even the S/S ones . Regards |

In the end I’ve made a opening from the liferaft locker siliconed and tighten the bolts and all good the opening is closed with a SS plate with 4 bolts - the nuts inside are welded on a two small rails siliconed to the hull and now all is good |
