So...did she move, and did she stay in one piece?
She did, I'm just about to write it up.

Glad to hear that the move went well and you're pleased with the results of your survey.
Look forward to the next instalment!
The Blisters we have are Localised osmosis, there are 2 stringers ( I think that’s what they are called ) that run either side of the hull, they are made of foam covered with fiberglass. It seems the forward section close to the chain locker bulkhead has allowed water to get in to delamination from poor wetting and the all thing was a water tank when we drilled into it. The Hull presents areas of high moisture content at the height of said stringers then goes back to green and acceptable moisture levels. We could actually do spot damage repair but were tempted to strip and renew the whole hull as osmosis WILL set in with old resins. (besides it makes no sense to not do it now)
Why make the job any harder than it is already ? Carry out local repairs on the blisters, dry the hull and epoxy it, job done. As for "osmosis WILL set in with old resins" how do you imagine the millions of boats with "old resins" have survived thus far, generally with little to no osmosis ? Most of those that have exhibited signs of osmosis have been either spot repaired as they show up, or spot repaired and epoxied. Osmosis isn't the pandemic problem you seem to think it is.
Greg & Phil,
Well done. Looking forward to seeing you progress with your boat. Its going to be tuff, but it sounds like your both up for it.

Hmm well Osmosis is something that 100% of boats made of resins old or new have.
Unlike most my fear is not that my boat will sink or break because of osmosis. Its more to do with delamination of some areas and where I am going to go sailing. I intend to sail in Greenland and Svalbard waters and do not wish to have ice crystals forming on the hull.
Osmosis in itself is not a major problem, most wooden boats survive much worse.
It is nevertheless a problem that requires attention and I happen to have all the means to do a complete dry out and address the problem.
I’m afraid I think like a German, If I’m going to do something, I start at the beginning and don’t cut any corners.
What utter nonsense.
As I think you may need to read a bit about a matter which you are pronouncing yourself in some form of authority I saw fit to provide you with some Links to research papers as to allow you to refresh your knowledge of Hydrolysis In GRP and its effects causes and prevention.
One is by Nigel Clegg for the University of Plymouth the other by Thomas J.Rockett, Ph.D. Vincent Rose, Ph.D. U.S Coast Guard Grant #1501.83 Sponsored by American Boat Builders & Repairers Association,Inc.

How do you think planing the gelcoat off with a home made planer will stop ice forming ? My boat was built in 1980 and it would happily withstand Greenland and the Arctic.
I think you’re not taking the time to think that statement through, Moisture Content in GRP WILL freeze under low temps. Nordic countries have huge sheds for boats. Just saying.
But I will indulge you and explain, the “home” made plane (I don’t understand what you mean by that but hey) will remove the old Permeable gelcoat and a new one with better properties will be applied over weave and a few more things. THAT is what stops water ingress not the plane.
Have a riddle for you: What has sails and floats sometimes with a high moisture content trapped inside the hull? and what happens when it freezes?
Not come across a wooden boat with osmosis yet.
Dissing someone should be done in a more REFINED way. You could at least have READ what I wrote. Wooden boats have other problems but I have seen at least 2 with osmosis and helped repair one.
The first had received a deck fiberglass over the wood that was poorly done and developed osmosis. The second had a cockpit door cover made of Fiberglass that even twisted with big blisters.
Wooden boats WITH osmosis. I'm starting to think there is A LOT you have NOT seen.
Sadly, you don't appear to have much of a clue as to what you are doing.
I’m not sure you realize that sometimes it is better not to say anything then be judged by ill thought comments of derogatory form. You may be perceived in a way that may not correspond to the person you are.
Consider this; My next video is about fixing a bulkhead. It will be done with very specialised materials that require in-depth knowledge that is not easy to come by and in some cases take specific training to use. Now should I be able to do something like that would you say it was fair to say that your comment about what I know or not may be perceived as “small minded”?
I wish you well with your boat build, but it's now reached a point where i'm going to bow out of this thread.
Good reply Greg, sadly wasted as he has stomped. Never to return. Absolutely not. Never. Ever. Yeah right
Have missed most of this thread, so I'm coming in at the end to answer the same old whinging comment on how it's not worth doing it yourself. Total rubbish!!! If I couldn't save thousands doing it myself I would never have had a boat. So far I am on my fourth build (and rebuild!) Every boat I built made money, not counting the labour which is hobby time and doesn't count. I used the profits to build up to my biggest boat - a 12 metre steel cruiser built from a set of plates. Total cost when complete £19,000. Later fitted a new engine and aluminium flybridge. Sold her five years ago for just under 70K ! Now rebuilding a 1978 26ft Reinell sports cruiser as I needed to downsize. There are certain rules to successful DIY building: 1. Never buy anything at a chandlery. 2. Find your local commercial suppliers of stainless fastenings, hydraulic fittings, mat and resin, Timber. 3. Give yourself a boating business name and open accounts at marine suppliers as you will be buying in commercial quantities. 4. Don't ever listen to comments that it is not worth doing as those people have never done it or had the nerve or skills to try! You'll love doing this and it may not be the last once you've got the bug.
Suggest you actually read the whole thread, then you might understand why this particular project is a lost cause......cut...... if he wants to go sailing he can buy an up and running boat of the same type now for less than half of the (minimal) material cost of completing his hull and deck.
Not sure why this is seen as a lost cause, nor why there is such apparent antipathy towards a couple of blokes fitting out a project boat for the craic. Even if they blow 2x the amount they could have bought a runner for, so what - it's a hobby and like all hobbies it costs as much as you wish to spend in the way you wish to spend it!
Crack on lads!
