Why Is There A HOLE THE SIZE OF MY HEAD in Our Boat? | Learning the Lines

In this video I continue the repair work on the cracking of the interior laminate of the main hull on our 1991 Corsair F27, Desperado. While prepping for glass, I found out just how nasty a previous "repair" made by the prior owner actually was.
For this video the focus is on the center section under the companionway. The next video will focus on the aft section under the aft cabin bunk.

Learning the Lines is a channel about us, an average couple in our 20's, with big dreams to be sailing the world by the time we're in our 30's. We're not afraid to jump into anything, put in the work, and learn as we go. We started out with Somnium, an O'day 272, moved onto Freebie, an Endeavour 32, and now are focusing on sailboat tours and working full time as teachers while we save up for our next boat.

[@dantoddruns]

I really think you did a good job balancing the detail provided and the pacing of the video. It made it very easy to watch and more importantly we got to see a fair amount of progress in one video. Cheers.

Thank you!

Thanks Carl, I enjoy making the DIY videos.

[@joelbrown4110]

Love the DIY and cant wait for the sailing.

[@sailor7312]

Looking good. Just an a thought. Getting the cuts straighter where you cut the tray out will make installing the new tray easier. A piece of wood as a guide w a router and you make long straight cuts.

[@davidhendrie6935]

Looking good. The balsa stringer looked pretty black around the hole, but you obviously thought it was sound enough. As I thought, you had to remove most of the inner floor, but it was well worth it. Being able to reinstate the laminate in one go was key to doing a thorough repair. If my cat couldn't get into my front garden, I don't know what I'd do! 🤔

[@z_actual]

the taper ratio is 12:1 so I think your good I would have another layer inside and one more around the hole and filler because thats where the strength is for an outside impact and holds the tensile strength, which is glass at its strongest cheers

[@frankpruse19]

Awesomeness!!

[@organicoceans4459]

Wow! How to fix a hole in your boat! Lol! That was Amazing Brother man! Good job!

[@lifeinchrist77]

The best method here is, taper the whole to the outside then fix a piece of Formica on the hull to cover the hole, wax the inside of the Formica, then jell coat it, two coats. Then put two layers of strand matt, put your core on this, using (crystic)then matt over the top of that. When all is cured remove the Formica fill in any holes with the same colour gel coat with a few drops of wax, or just put Sellotape over the parts you have filled, allow to dry, sand with 2000 grit and polish.

[@salomedaniere3618]

I'm not sure what's available in the US (french here) but using vegetal linen (like flax) instead of fiber glass makes the work so much easier and less unpleasant, works a charm and it's quite sustainable. Used it for repairs on our sailboat, and to built a catamaran, it gaves great results.

[@miacondia6032]

Good stuff Jordan, best to buy boats with no holes in it

[@jefflove7791]

Glassing upside down is always lots of fun!

[@fooman2108]

One of the best things I have found to thicken resin is the dust from the fiber-glass you made cleaning it up.....

Did you say "Kevlar"...you are so lucky! I enjoy your videos so I am clicking on the Subscribe Button! God Bless, and wishing you lots of luck with your projects!

[@allynonderdonk7577]

You need to do the bearings on your trailer and address the rust. You should get new tires and also work on the brakes if it has them. Marine trailers are notorious for axle problems, bearing problems, and corrosion issues. Also if the tires are more than five years old replace them and make sure you have a spare available.

[@stashtrey1]

This is the truth. I had an old jet boat in my early 20's (45 now) and spent a summer going to the river. Had a blast until one evening driving home, down a freeway, and the trailer started wobbling....I looked in my rear view mirror just in time to see the wheel about to separate. Terrifying when doing 65mph on a freeway at night. The bearing exploded....I learned right then and there to always grease your bearings!!

[@fooman2108]

@@stashtrey1 I am an OTR trucker and I probably AVERAGE about one boat trailer a DAY during boating 'season' usually with a wheel gone or rotten tire flat.

For sure, trailer work will come soon. I plan on rebuilding/replacing most everything.

[@CajunWolffe]

Yep, I used to live in Galveston-Jamaica Beach and keep my boat there. Every year I was doing something to that trailer. If you live on the coast, you'll understand when I say freaking plastic will rust, metaphorically speaking, of course.

[@LearningtheLines]

One of the best features of these boats!

[@williamfennell8175]

It looks good. No matter what happened, it must be a step in the right direction. Can you provide some info regarding the seams visible in the bilge before and after your repair? Do they indicate individual strips of core material? Are the just locations of the cracks in original laminate? Do they line up with any structural hardware/ stress points like stringers and trailer? When doing surface prep while sanding and looking for good glass, did you ever test the bond strength of glass to core in the cracked areas? Besides the rotted balsa, what type of damage did you find anywhere else in the core? Water penetration, fraying, compression failure, bond failure on either side? How much thicker is the exterior laminate compared to interior? …again, good job.

[@stephenshort839]

That "uncured" epoxy was a good lesson for all DIY glassers. Good job on the repair so far. Are you thinking of another layer of glass on the bottom of the hull to reinforce where it's been bumped on rocks and the trailer?

[@LearningtheLines]

It's possible but I need to be cognizant of adding too much weight.

[@giles-df9yu]

The main lesson is not to attemp a plug the whole thing needed to be cut at an angle to give strength

Hi there : ) What is the name of the beautiful song in your videos? All the best to you!

[@fudogwhisperer3590]

Does the epoxy come with premeasure pumps? The pumps are why I like total boat and west systems.

[@LearningtheLines]

It does, but you have to count them out meaning the pumps all pump the exact same amount. This resin is 2 to 1, so 2 pumps of resin, 1 pump of hardener.

[@garygarnett6469]

Was hoping the hole repair from outside was done a lot slower I have to do the and being the first time great to learn from other peoples mistakes if they made any

[@6800891]

Would be interested in a calculation of cost savings of driveway storage and the labor for these repairs.

[@djmjr77]

For a diy yard you can work in(here in SFL), your looking around 500 per month possibly closer to 1k depending on needs(electricity, haul out, water etc) and location. About 75+ per hour for quality fiberglass repairs. Putting those costs aside the convenience of having the creature comforts of home and just being able to walk outside and do work is in my opinion invaluable.

[@melee401]

As straight forward a lesson on hull material replacement involving coring one could hope for. For some reason I do not see keel balsa coring surrounded with Divincell as having the ability to produce near the issues of hulls cored in full below the water line man. Then you have the builds where the balsa coring was kept above the water line, and for real good reason. All the new balsa matts come with each block treated with sealant. How long that lasts only those who have played it out can tell you. It is a great improvement over the balsa coring used in the 70s. As far as your carpentry skills,,,,,,,,,,,,,,,,,I would take in Aladino on Sailing Magic Carpet and take in some more patience.

[@ianallan2337]

Given the issues this boat has had consider a layer of carbon fiber down the centerline. Not much glass there now from what I see.

[@LearningtheLines]

I am considering doing this. It wouldn't be that much extra work or expense.

[@ianallan2337]

@@LearningtheLines For sure. the stuff is amazing. I had a Kirby30 with a weird spar that once I saw go into a pretzel-like shape on a spinnaker run. We epoxied AND pop-riveted a carbon fiber layup to each side of the spar and absolutely no more worries. At least10 years and mucho abuse.

[@extrameatsammich]

Did that boat get dropped?

[@Jyskall]

I would think the same, dropped or ad some time hit a reef or rock. But it seems that is was standing for years on the trailer not correctly supported and had rain water inside...

[@LearningtheLines]

No, but it did go through Irma on the trailer. Lots of wind and rain.

[@RaiseHull]

@@LearningtheLines Looking at the cracks in the videos before I thought it looked consistent with being banged against the trailer and maybe more. Now the damage makes sense. Outside impacts from the trailer. These boats are relatively light but have lots of windage, not unlikely the boat/trailer combo rolled and came back hard, maybe more than once.

[@Imightberiding]

It's good of you to show your process, inexperience, mistakes, short cuts & general overview of not really knowing what you're doing & painfully obvious lack of craftsmanship. This way potential buyers will know to steer clear of this boat when you put it on the market. If you think your workmanship & repairs are "adequate" then perhaps you should keep it for yourself & enjoy your future trouble free sailing excursions on this boat. *Edit: As a professional carpenter, cabinet maker, general contractor, craftsman & experienced boat builder, I hate the terms: "It's good enough" or "It's close enough" or "I could have done better". Don't take short cuts. Inspect the entire boat/project inside & out before starting anything & just do it right the first time. If you're just trying to turn a quick profit that's one thing. Although I have never thought highly of those who do this but just be honest with yourself. If you were doing this for the long term to keep this boat for you, your wife & child to sail safely in it, would you do the same things you are doing?

I don't understand why the previous owner would accept such a lousy repair? Are you not able to tell if it had cured or something? I just can't see half assing a repair that could literally sink the boat if not done correctly....

Previous owner's health is fading. I don't blame him.

[@breezyjr]

@@LearningtheLines I didn't really mean to assign blame... I just wonder about the repair... could he, or someone else not notice it..? Can you not see it without cutting into it? I understand if it was his health that kept him from noticing it, I'm guessing at a quick glance you wouldn't be able to tell...

[@enduranceG51]

Not trying to be a pain in the ass but Unfortunately your hull repair will fail. I am a marine engineer and a Naval Architect and feel compelled to help you. The exterior glass work should be a minimum of one foot past the edge of the feathered out glass hole. Also your interior glass should have biaxial glass to spread the load forces and go as far as possible up the hull sides. Not sure what the white rectangle is doing, but it should have been removed so your glass work is continuous from edge to edge. Hate to see you go through this and be back at square one or worse yet sunk. So sorry, and best of luck. If you need any help contact me. Tom

[@LearningtheLines]

I understand your concern, but West System marine engineers seem to disagree. www.westsystem.com/the-105-system/reinforcing-materials/determining-laminate-thickness/

[@enduranceG51]

@@LearningtheLines Not at all. I did research for Ciba Geigy. The World's foremost epoxy resin inventor. Our research was on composite bonding between polyester and epoxy compounds. West System, System 3, and all the others used our research and resins as the basis for their epoxy. Simply put. Your reference is for a minor repair in a non-structural fiberglass panel. It's hard to beat 50 years of boat building and aircraft building experience. Just trying to help you out a little.

[@LearningtheLines]

Thanks for the input. I'll consider adding an extra layer on the exterior with more overlap. On the interior they'res plenty of overlap so thats not an issue. It's exactly like you suggested, biaxial 1208 going all the way up as far as it could go on the hull sides.

[@noqnoqrvfitouts7683]

Is there some rule of thumb what gradient the feathered area should be? I would think the thickness of the laminate is a factor , so if you say it needs to be feathered a foot past the edge of the hole will that be less for a thin laminate and more for a thicker laminate ?

[@seancollins9745]

Don't spend more time avoiding the work, than it would take to do the work. Probably faster to cut away the bad glaaa and rebiild it, cut back to the good areas, stop trying to salvage bad glass

[@LearningtheLines]

I respectfully disagree. If there was massive delamination and/or core rot, 100% I'd cut it all out and start fresh but there wasn't. Most of the glass was good and most of the core was good. Every repair is a balancing act to get it right. Do too little and you didn't repair it, but do too much and you're potentially creating days or weeks of completely unnecessary work for yourself. I think I found the balance here. Time will tell.

[@shalaconballard9912]

Balsa was used because its a cheap way to make up a fiberglass hull and make it appear thicker than just using all fiberglass aot of boat builders used the crap and that's all balsa is crap .

Plus he gets a sailboat that he can go out sailing in that is fast and fun and there are no docking, storage or haul out costs. If he does find a way to spend more than $20K on it, that will just be the cost of having fun.
