That fiberglass repair isn't strong enough. Should have been a minimum of 12 layers of fiberglass. Each layer is about 1mm. Charles is a great friend to have willing to help out like that. More sanding and grinding should have been done on the outside. To get down to better fiberglass for better adhesion. There was enough room to bring the glass out 6 times the width and length of the crack. Witch is critical in high stress structural repairs.
I once bought a cheap 34 ft ply & glass cat , taking it out of the water for the first time i had bought two wooden lampposts to rest her on , One of the posts a had borer in , broke in two & went frew the hull , filled with water - It all come right .. Nice post .
I would not get on that boat. Can't patch over a crack. Laying a few sheets over a crack does not "Tie In" the layers of fiberglass. You put a band-aid over a wound. And what happens when you get a band-aid wet?
Just watched your film. Looks like the repair is probably holding up ok. I did not like the use of wood in the repair. Adds little strength and can easily get wet and then rot out. Please check it regularly. The theory of encapsulating in resin is only theory, a tiny pin hole and it just traps water causing rot. What worried me the most was the type of crack . I did not get many close ups but I could not see many fibers in the laminate in the crack .Makes me worry about the low fiberglass content of the hull. The good thing no balsa coring in the lower hull. I built boats in the 80's and balsa coring was all the rage. But now as I look at old boats built in that era ( all I can afford) the balsa rot in decks and hulls is way worse than I would have expected. We used to say coat it in resin what can happen........a lot! And it's a real mess to repair. Foam did not come out much better either. So the extra weight is a pain but solid hulls in old boat is way more reliable if they were built strong enough in the first place. Good luck , I think your fine for coastal cruising ...... Cheers Warren.
Thanks for the information. We do check the area regularly and it is holding up well. ☺ We agree about your assessment about the low fiberglass content in the original structure. Many Gem owners reinforce areas of their boat; flexing during heavy seas is a common problem. We will continue to keep an eye on the patch. Thank you for watching. ☺🐈⛵
@@Rick-tb4so .........Various types of composite honeycomb webbing are available, but I would still go with only solid hull below the water line for strength.
Any time you grind fiberglass put on a mask! Also did they grind the exterior hull after the fiberglass and touch it up then reapply base coat then bottom paint? I did not see it but did the survey not pick that up? Now, I think you guys are going to be fun to watch. I can tell your smart, adventurous with a can do attitude. I really look forward to following your adventure. You guys will do great! Fair winds and GOD bless, JC
Thank you for your kind words, JC! We did find Charles a mask later on in the process. We didn't manage to get the base coat on, but because the hole was right at the bottom of the hull, we figured it wouldn't get too much damage from UV. We plan to haul her out in December to fully sand down and repaint the bottom. As for the survey - the crack happened sometime after the survey (after we took ownership but before we took possession). We had noticed some hull recession but there was definitely no crack. We think perhaps a combination of factors - wrong placement, boat getting fully loaded (including full fuel tanks), and a longer period on the hard may have all contributed to the crack. The good news is that we now feel much more prepared should we need to do a fiberglass repair again. :)
The 1st epoxy bottom coat is in part to keep water from saturating your hull. I am pretty sure you do not have a cored bottom but even with a solid hull the redone damaged area will need to be addressed pretty soon. If not you might create a problem of moisture there. On you tube there are several channels that cover hull damage and repair. ? Oldboat? I think and some others go over the correct procedure. Please if you guys can find the time research "hull bottom fiberglass repair" or words similar. Don Casey would be good to look up too for his thoughts and recommendations in his books and articles. I just want your guys investment to last a long time and to be safe and happy sailors. I have no doubt you guys will get it figured out and fixed and enjoy many, many years of sailing. Look forward to watching you guys get to warmer water! Look out Bahamas here they come. JC
Perfect, thank you so much for this information. Perhaps we'll pull her out sooner rather than later. :) We are also looking forward to warmer water..... can't wait! :D
Good question! When we surveyed the boat, we noticed slight recession of the hull, but no crack. We actually have close up pictures of that exact spot! Our theory on why the crack happened: 1) the original owner had switched hauling companies this past spring and they asked for a different set up with long wooden beams (he was using cinder blocks and plywood previously). 2) We think the new company set down the boat at the wrong place, which caused the hull recession. 3) As the owner prepared the boat for transport, he added more load (including filling the fuel tanks). Our best guess is that the combination of being on the hard for a longer length of time than normal (resting in the wrong spot) + slightly more load caused the hull the crack between our survey and transport day. These things happen. Luckily we were able to address it and as you said - it made the boat stronger than ever. :)
Interesting. I guess these thing happen! Lucky it was noticed before you launched! One boat we purchased had a similar-but-different issue. There was no visible problem, but the surveyor's moisture readings of the hull uncovered a soft spot on the port side. If we had put the boat in the water, water would have quickly seeped through and sunk the boat! We had to cut out the affected area and replace it with new fibreglass. The theory in our case was that the boat had been damaged (perhaps being dropped too hard onto a cradle) and then patched with a very poor repair. Lesson learned: always survey your boat *before* you buy it, no matter how good shape the boat looks to be in! Can't wait to see about your first sails on the new boat!
You're absolutely right! We actually just heard a story of an experienced sailor who purchased the boat without and survey and unfortunately lost his vessel in the maiden sail. Yikes! Glad things turned out OK on your end too. Learning to patch is an important skill and we're happy we got to learn about it with the help with friends (and on land!). We can't wait to be sailing soon either! :) Thanks so much for watching and commenting. :)
I hate to tell you this, but I have real reservations of this 'repair'. The reason I say this is that I have performed quite a few frp repairs in the past. So here's part of my concerns, 1) a guy who does not know how to dress properly and safely for this kind of work is very suspect as to his sanity and experience. 2) at 2:12, it looks like the hull is about 1/2" thick, f not more, that equals ~ 16 layers of bi-axial (cloth) and/or possibly several layers of woven roven (real heavy stuff) depending on the manufacturers original lay up schedule. NOT three layers on the inside and three on the outside, which looked like chop strand mat (the weakest glass). 3) the crack should have been ground to a taper on the outside at minimum ratio of 8/1 if not 12/1 and then progressively filled with the appropriate glass lay up. This is not a quality permanent repair, please, please, please do some research on your own and decide for yourselves. Sorry Charlie...
Thanks for sharing Charlie! We didn't show everything on the video, and the edges were tapered before we started glassing. We appreciate viewers speaking up. It's held up through 18 months through some heavy seas with no blistering or other signs of decay, but we're keeping an eye on it
So we think it happened after survey but before transport. 😐 We actually have pictures of that exact location during the survey and there was no crack.
We used some left over plastic wrap from winterized boats. I'm not sure what' it's called but there were loads of sheets floating around the boat yard.
Sailor, I don’t want to hurt your feelings, but that is not the way to repair fiberglass. What you have done will work for an emergency repair to get you back home. When you get home hire a professional with a shop and good reputation or read and study fiberglass repair. Watch many you-tube videos. Understand their are many people on you tube that don’t have a clue. They slept at a Holiday Inn Express last night!!! Look until you know how to do it. Your boat is a sinking looking for a place to happen.
It was definitely a learning experience. Luckily for us the repair has held solid until now (3 years) and the boat has been through heavy seas and rough weather. What would you have done differently?
these people are so stupid you cannot repair a boat crash like this it will break the same place again once you put in the water and stop running what you need to do is get a brand-new Hall
What would you suggest? The repair is still holding, and has been through heavy seas and rough weather. Please keep in mind that we didn't include 100% of what we did for time efficiency purposes. Thanks for watching!
I grind fiberglass bare chested in swim trunks only sometimes, way too hot for a tyvek suit. The key is to imediately take a shower, then go back to the project. I try not to knock people's repair work. In this case I must comment. Your life is at risk in a boat subject to poor hull repairs. I would take the boat to a boat yard and have someone repair it properly. The repair You performed should not be trusted....sorry. Take care
What would you have done differently? Please keep in mind that we didn't show 100% of our work on this video due to time efficiencies. The repair has held until now and the boat has been through heavy seas and rough weather ☔😊
As Bill writes that is only a temporary repair. Don't sail too far away from the shore. Maybe check out some of the videos with Andy from (Boatworks today) they could give you an idea about how it should have been done. Good luck and stay safe!

Way to go Charles!! Its so awesome to have great talented friends. Love the humour in the video too. Hope that's the last of the surprises.
Im an Aussie just started following you guys, now working my way through your journey, hope the audio improves, cheers.
Thank you for following our journey! I think our audio skills are getting better. 😊

Yup, looks like a guide on how not sort a crack, Kinda horrified that the yard let them put that in the water.
You only used 3 layers of glass? Also did you not grind any of the inside of the crack to expose fresh glass to bind to?
What type of paper was that you put over the epoxy resin?wax paper?
Technically sound repair.

Is there a material that could be used as a core that is 100% water proof ??

I've heard of the Green Flash in Mexico, but I did not know it happened in The Bahamas!
Oh, man, I don't know how you can grind fiberglass bare- chested! Itch-o-rama!!
We've had so many comments about that! Apparently Charles has dragon skin; nothing bothers him. Thanks for watching! 😃⛵🐈
Now that is what I call a hole! Holy smokes, good to have friends with know how!
Yes, we're very grateful for our wonderful friends. It was also nice to learn that we can fix the boat if we needed to in the future
Looks like the fix has made the boat stronger :)
Didn't the survey uncover the crack before you bought the boat?

That isrong ser
How the hell did your surveyor miss that one?
So we think it happened after survey but before transport. 😐 We actually have pictures of that exact location during the survey and there was no crack.
Yep got a new sub here.
Thank you for following our journey 😊
That is easy to fix
It was a great lesson for us 😊
What do you call the covering you used to wrap the fiberglass while it hardened?
We used some left over plastic wrap from winterized boats. I'm not sure what' it's called but there were loads of sheets floating around the boat yard.

Buy a hole with a boat around it......😂⛵️⛵️
Lol pretty much!!
Holy moses what a shitty repair.
