In this episode the Osmosis repair on this Contessa 32 continues and is close to being finished by the end. Having peeled and dried the hull in the previous episodes I now lay up a new skin of glass biax cloth over the hull with epoxy resin, I can then fill and fair the hull using my trusted FlexiSander tools using the same resin (thickened as required). I also fit and fair-in the new central log transducer housing and do a lot of sanding, I then do some more sanding and when I’m not sanding I ache…..then I do some more sanding. The end result is a perfectly fair hull, better than new in many ways as I also fair out some defects from the original build.
Stay tuned for the final video in this Osmosis Mini-series as I still need to dry and repair the rudder, refit seacocks and apply both a barrier coat and Coppercoat to the hull.
Note - I am in no way sponsored by FlexiSander but I do like their tools for this sort of job
Note - I am in no way sponsored by Gurit (the epoxy manufacturer) but like their products
Note - If a manufacturer does want to sponsor me or offer products to try out feel free to get in contact :-)
Many thanks to the owner for giving me permission to create this content based on the refit of his boat.

About Me
I run a small business called The Solent Boat Butler and spend my days repairing, maintaining and refitting sailing boats (often Contessa 32’s due to my long experience with them). I'm mostly in the central Solent area of the UK. Being a cruising and racing sailor with many thousands of inshore and offshore sea miles logged I like to think that I bring a great deal of real world experience to my work and help many new (and not so new) boat owners to improve and maintain their boats. When I'm not fixing boats I also provide some own-boat sail training, help owners with deliveries and provide consultancy services to those that are refitting their own boats for cruising or racing.

When restoring cars we will do what they call a rotisserie restoration. It basically puts the vehicle in the optimal position to work on. Seems to me they should be doing this with sailboats to alleviate all this overhead sanding. I can see how everybody starts off very gung ho on perfection and then settles for close enough. It looks exhausting.

The static effect was just amazing! No one had shown this before i guess. Great and very informative video! I don´t know hof much editing work it would mean to you, but do you have the ability to integrate timelapses? I love watching a thourough video like this one, but imho the addition of more dynamic elements would elevate them even more. As a viewer the perception of this vid is you show the boat, explain very interesting things show a some details but the camera is mostly showing the static picture of a boat. Then you cut and explain that you did lots of filling and sanding and explain detailed changes but again in the picture is just the boat. What other channels do and I think adds a lot to the excitement ist putting in timelapses showing the actual work being done. Imho some of the viewers attraction of project channels like yours is watching actual people doing actual manual work. For many people i guess this is a rare sight nowadays. I don´t know how much additional work that would be for you but imho it might add even more to the enjoyment of watchign your great work. Some examples of what I mean might be Acorn to Arabella, Dan Chambers and Expedition Evans. Cheers!

Thanks for the comment, really appreciate the thoughts. I will try to include more timelapse clips on videos as I can do it. The thing for me is that I do youtube vids as a side project to the real work of fixing and refitting boats for a living so try not to spend too much time on it as I have to earn a living in the real world and get my customers boats back on the water ASAP. I will take onboard your thoughts and thank you for taking the time, I can only get better though the advice from others.

@CrewsFarm Год назад

Another very interesting video, George. I don't think my shoulders are built for all that sanding - although I shouldn't need to worry about this for my boat for a while!! For some reason I imagined that you would need a complete layer of fairing compound or whatever (on top of the fiberglass) over the whole hull equivalent to the original layer of gelcoat, and I always wondered how you would achieve an even thickness and how the hull profile would be maintained. Now I know! Quite interesting that you are planning to remove the wet foam in the skeg from inside the boat, because being un-enlightened, I would have cut an access panel in the side of the skeg to get better access and perhaps make it easier to get all the foam out. I would be interested in your reasoning. Have you glassed-in the new GRP stern tube yet, because I've always wondered how you do this? Incidentally, in later glimpses of the neighbouring boat it looks as though the hull is now grey epoxy/primer/antifoul or whatever. Has the coppercoat been replaced?

@RefitandSail Год назад

Hi John, pleased to her you enjoyed the video. I will remove the foam from the top of the skeg as I think it’s going to be easier than cutting an access hatch in the side and then making that good after. Also the new foam will need to be poured in, it expands in place so really needs to be poured from the top rather than the side. The plan is to remove the engine and the bulkhead behind the engine to afford better access to the top of the skeg and I can fit the new seacocks at the same time. Your boat does not have that extra bulkhead after of the engine. I will fit the new stern tube once the foam is all out, it will be bonded at each end and the new foam will also secure it as I will be using epoxy boat which is also a semi structural adhesive (that is often used when building rudders on more modern boats. Boat neighbour in the shed has had a gelshield epoxy coating applied and will get its copper shortly I believe.

@justinstoker3115 Месяц назад

Amazing vodeo series thanks for the insight. When you say material blast is that similar to sandblasting? If so is it just sand or a sand and water mix? Could the same result be achieved with a steong pressure washer like you did with the rudder? Cheers.

@RefitandSail Месяц назад

I think the media used was crushed glass but I leave that to the experts who do it for a living as different media is used on different materials. Needs to me more than a water pressure wash unless you have an immensely powerful pressure washer.

@Manny_Akamotakis 9 месяцев назад

questions: could an extensive media blast be done instead of the peel? was there no gelcoat reapplication? thanks.. Love your work mate

@RefitandSail 9 месяцев назад

Potentially but it would take a very skilled media blasting operatives to get an even removal of material. That’s why boats are normally peeled.

I think I mention the weight of the glass in the video, from memory it’s 300g but may be 350g.

I've drilled out with a Dremel some inspection patches through the Gel coat on my Contessa and now I'm ready to fill them again with International Watertite filler. My question is where around the patches should I paint my undercoat primer ? Should I prime inside the drilled out holes or leave that bare for the Watertite to bond direct ? Will the smeared Watertite bond to paint primer ? Thanks in advance.

@pironiero 5 месяцев назад

why didnt you leaned the boat like 5 degrees on one side to have opposite side free to lay out the glass layers lengthwise?

@RefitandSail 5 месяцев назад

I don’t think that would be particularly safe in a cradle. It would be better maybe to have a cradle that had pads on the hull above the water but that’s not available to me. Also easier to handle smaller lengths of glass

@matthewsellers82 Год назад

Showing my ignorance, with the weight being carried by the keel in a protected environment, why not put the pads above the waterline?

@RefitandSail Год назад

No ignorance at all, the boat is on higher than normal blocks so I could access the bottom of the keel and the arms on the cradle are not long enough to reach up onto the topsides. I agree this would be the ideal solution and I can do it with my own cradle but not possible with the cradle I have to use in this yard. Using two cradles makes it less of a faff but it’s still a faff doing under the cradle pads. Thanks for the comment.

@user-jj7vh2os8j Год назад

Amazing workmanship. I have a Contessa 32 and would like to install an Airmar transducer in the bow similar to what you have done in this video. Did you fiberglass the bronze thru-hull into the hull, or use 3M 4200 so it could be removed at a later date? Did you have any problems with the length of the bronze thru-hull in that location?

@RefitandSail Год назад

It’s bonded in with thickened epoxy and then further reinforcements added internally (epoxy thickened + chopped glass strands).

@user-jj7vh2os8j Год назад

I have just completed the installation of the Airmar transducer in the bow of my Contessa at roughly the same location as in Project Lottie. Very tricky because of the sharp angle of the vee in the bow but fortunately the bronze through hull fitting was long enough. I added about twenty layers of fiberglass cloth inside to create a level mount for the transducer. After drilling the two inch diameter hole I wrapped the bronze through hull with plastic tape, then inserted it as a temporary form. Then I added eleven layers of 1708 biaxial cloth to the outside of the hull on each side of the transducer, beginning with a large piece and with each subsequent piece slightly smaller in area until the final piece just covered the transducer itself. The result was a linear transition which was half an inch thick around the transducer and required very little fairing. Then I removed the bronze through hull, cleaned it up and did a proper installation with 3M4200 so it could be replaced in the distant future if necessary. No leaks. It worked out beautifully, but would not have been possible without your inspiration -- you showed that it was possible. Thanks again.

@nickshipman620 Год назад

Great job really enjoying watching your videos , hope you dont mind me asking but what weight biax did you use? I’m assuming it depends how deep you plain ? and what fairing filler additive have you used , and are you using west system epoxy ? Thanks again

@RefitandSail Год назад

Thanks for the comment. The weight of glass needed to refinish a hull is dependant to a great extent on how much needed to be removed for the drying to be successful, I used one layer of 300g biax on this boat, if I had needed more material I could have used 450g or two layers of 300g. While I have used WEST in the past I am not using it for this job as I believe there are better options. WEST suffers very badly with amine blush when curing and I don’t want to be cleaning that off every time I use it as it’s just a waste of time. I have used Gurit Ampro epoxy for the whole job and am using a mix of West low density filler and Q-cell for the additives because I know it works and while there are premixed epoxy fillers I could use they are more expensive and I want to use the same base epoxy system for the entire repair.

@nickshipman620 Год назад

@@RefitandSail thanks for taking the time to reply I will def look into the gurit ampro epoxy ,also if as you say on a job you might use 2 layers of 300g biax Is there a reason to not just use 1 layer of 600 ? , would that build the same thickness in theory?

@RefitandSail Год назад

@@nickshipman620 no issue with using one layer of 600 other than it will take a bit more effort to wet out (remembering that epoxy likes to be warm and it much much easier to wet out glass with warm epoxy/hull). It would also be physically heavier so getting it to adhere to the epoxy on the hull prior to wetting out may be trickier but doable with a helper I expect.

@superformOG Год назад

George what do you think about glassing both sides at the same time with a single piece of glass so that the join is not on the hull centre seam

@RefitandSail Год назад

Probably hard to achieve both sides at the same time as I use masking tape on the peel ply to help the glass confirm to the tight radius at the lowest point, if doing both sides (on a co32 at least) it would be hard to get the glass to take that tight radius on its own.

@williambailey5405 10 месяцев назад

Is all of this work cost effective versus buying a boat without the problem?

@RefitandSail 10 месяцев назад

Depends on the cost of the boat and what the long terms plans are I guess. Of course it would be nicer to buy a boat without osmotic blistering but unless you wish you spend 300k GBP on a new co32 then you are probably looking to buy one that was built in the 70’s whish is when the majority of them were built. Because these are all old boats now any have a degree of osmotic action/dampness in the hull, many have had this sort of work and some have not (or may not need it if they have spent long periods ashore in that 50 years. I think what I’m saying is if you are buying a 30-50 year old boat you have to expect some of these old-boat issues.

@RefitandSail Год назад

Hi Graham, thanks for the comment, I’d rather not put my pricing in the public domain here as I have agreed with the owner not to discuss pricing in the videos. I’m more expensive than some (but their work is of variable quality in my opinion) but cheaper than others as I’m independent and don’t have the overheads of a larger yard. Every boat is also going to be different in terms of how long it needs to dry, how many seacocks to remove/replace, will some areas need a second peel, what other issues may be found as they have on this boat.

How do y9u apply unthickened epoxy on top of fresh thickened epoxy? The thickened layer doesn't get 'pulled' and disturbed by the top layer of sticky clear epoxy?

@RefitandSail Год назад

As I filmed this a short while ago now I can’t think which bit of the video you are asking about but as long as it’s warm so the epoxy is reasonably liquid (it becomes more viscous when cold) it is possible to carefully roll or paint unthickened epoxy over thickened epoxy without disturbing too much although it would be easier to do it once the first layer has gelled/set up to come extent so it’s firm (if not hard).
