Looks great Mike. Having the livewell up front will be very convenient and greatly improve your ride in the chop. As long as the hatch seals up tight and the water doesnt slosh the baits will know no different.
When using dense foam like that, do you have to super beef up the layers of fiberglass on each side of it in order to retain the same strength characteristics as lumber cored transom? I like the idea of using divinycel or etc, but not at the cost of having to add umpteen more layers of fiberglass laminations. I may be completely wrong, as I'm just guessing you'd need thicker glass installed to retain the same strength for dynamic twisting and whatnot. I'd like to know more about this.
Nice build, I love seeing an all hand laid boat come together. Although, if building that size and doing an open lay up... I’d have a resin gun to do the wet out with. 👍👍

That is closed cell polyurethane foam. Polystyrene foam melts on contact with polyester resin. Again you can't use CSM Fibreglass with epoxy resin so it's highly likely to be polyurethane foam
Hi, I have Campion Explorer 622 WA and would like to remove old stringers and put some new ones. But I dont know how to remove the upper part of the boat from the hull. And I dont know the exact measures for stringers. Any advice?
The forward bait tank. Won't the bait get pounded in the bow with rough sea's bruising them up or killing them more than a stern tank? I know everything is a compromise just asking.
Fantastic series. Wood used to be a weak point (rot)..Now with no wood anywhere the aluminum gas tank and lack of access to it seems to be the failure point now for most built today. How are your guys bedding the tanks?
After the skin layer of glass against the gel coat, the 17 and 18 glass. How many layers of each are put on top of each other? Is there an overall thickness that the hull has to be?
Capt. Mike at the end of the video it showed you hitting a laminated fiberglass (Stringer?) Compared to hitting wood with a hammer, been there done that, yes it shows its strength but it also shows the lack of flexibility, that is going to be apparent on the ride, I would suggest putting a rubber runner mat on the floor, your back and legs and butt will thank you for it, Just Sayin Happy Boating
This wet layup technique would be fine if they paused every few layers and vacuum bagged the mold, but this wet layup with no vacuum bag is going to have voids and extra weight and extra resin which makes the part weaker than it would be if it had the proper amount of resin. VACUUM BAGGING ISNT HARD, at the minimum a peel ply layer could be applied without the vacuum bag to at least prepare the surface for the next bonding. They didnt fully prepare the cured fiberglass surface when they used that angle grinder, they barely touched 1/3 of the surface area.... so the next layer of resin and fiberglass will only bond to the areas that have been sanded, the areas that were not touched by the back and fourth pattern will not be bonded properly. This whole process is filled with flaws and reminds me of doing fiberglass work in highschool in my driveway. Im not saying this wont work, but its not optimized or as strong as it could be with a few professional methods that dont cost much money, and would actually save time in labor when it comes to not having to sand the whole thing before bonding another layer because you use a peel ply that puts a rough bonding surface texture into the resin.
marc jordan this is not the way any professional composite team would make any composite part, and the fact that this part cost 6 figures makes my skin crawl. I’m posting my criticism not to be a dick but to educate the buyer who might want to purchase a boat made in this way. This is missing steps that will make this part heavier and weaker. this might be designed into the hull so it’s overly strong to compensate for this method, but that means it’s far heavier than it needs to be. regardless if a composite hood or fender that cost hundreds of dollars can be made properly with vacuum bag, or infusion methods, than this 6 figure boat can be made properly and still make plenty of money. It’s sad. This is practically theft!
It appears to be Poly Isocyanuarate It typically has a 2# density and in this case its used to form the stringer, the strength comes from the glass,, Its a very smart way to do this task, The Poly Iso foam with tolerate the Styrene from the resin
Hello, I am thinking to have a small sauna in the after cabin of my glass fiber sailboat? May this project go well if I investering in a proper isolation? Or is that just an insane idea?
Yeah. LOL. Working on my boat, too. It's a 1994 MAKO 191. Putting hydraulic steering on it. I am not too fond of bragging even though this guy seems like a decent soul.
Not judging, I have never glassed a boat, but from experience making performance car parts out of fiberglass and carbon fiber, that looks to be way too much resin. It adds weight and is more prone to fracturing.
@@rclakeman7453 fiberglass is not brown nor does it have creases in it, plus when cutting with jig saw it tears jus like cardboard and very low dust other then some foam pieces..
@@fixingtogofishing What they're using could be cardboard I suppose but all the polyiso roof decking I've seen is in fact a craft paper color fiberglass facer. If I could post a picture I'd show some.
Looks like 2” or 2.6” high density polyiso foam board used in the roofing industry it has paper backing look up Firestone John Manville Carlisle . I can tell you this this as a roofer for over 30 years this foam ever gets wet it expands and becomes mold . Very cheap way to make a so called stringer . Without cavasil even glueing the board down to hull leaving air gaps unreal shit work this guy getting ripped off and I’ve never seen or heard of a stringer being over 2 foot high these boxes are not stringers stay away from this builder and the roofing board for use in a boat .
First congrats on the boat build, I was excited to see "no wood" very disappointing to see no coosa boards either...I know you did your homework for long time what part did you missed ? Yes the boat will be very light, nothing to compare to a real build from full fiberglass. wonder what size waves do they rate those boats ? And I hope the transom core will be from coosa board.
Coosa is too heavy to use for stringers, it will be used in the transom I'm sure. The foam is just there as a form for the fiberglass to make the stringers it really serves no purpose after the stringers are done so they want it to be as light as possible, and closed-cell.
So in.your response you understand the foam has no structural purpose so all it is is the layers of fiberglass on on two sides, well those layers in there at that hight would not serve as structural Stringer eventually will fail, that's my whole point very weak and cheap way to build something that is suppose to last years for happy customers. Boat Builders know that Coosa board is much better choice but very pricey and maybe going to be a tough sale... that's all it is about the money.
@@slinky8559 Your comment really makes no sense, you kind of made my point and just repeated what I said... I'll say it again, the foam isn't structural and really serves no purpose after the stringers are built, so tell me again why you would waste probably $6,000 plus on Coosa board that isn't structural and is heavier than foam?
The stringer material is mostly in compression and at that height with the chosen FG materials the stringers are perfectly fine. Coosa is just a FG reinforced version of the same PU foam they used at a little hight density. Coosa is a great product but will still fail if not properly glassed. Personally, I would have chosen something like divinycell h80 or another pvc based foam over the polyurethane but that would double the cost of the stringers. Many builders use hollow fiberglass stringers made from chop strand then foam fill once glassed to the hull.
Everyone want to be shocked, find out what the materials cost for a boat build and what you are then charged for that new boat. I do fiberglass for a living. Yep, you'll be pissed.
So let's look at some details since you are in the industry. What did the NA charge for the design? What does a mold of this size and type cost? What are the layup/fabricators making an hour in S FL? How many labor hours in a boat of this type start to finish? Lastly, what are the materials costs?
Looks great Mike. Having the livewell up front will be very convenient and greatly improve your ride in the chop. As long as the hatch seals up tight and the water doesnt slosh the baits will know no different.
Excellent build, cant wait to see it finished. Did they tell you or do you know what the actual stringer foam coring product material is?
Looks like divinycell
roofing foam

@Bobby Pablo yea, have been using Flixzone} for since december myself =)
Going to love your bait and water coming out of front baitwell when wave hits or your front is up
Nice build, what kind of foam are they using for the stringers?
Extruded polystyrene foam. Also known as xps foam if im not mistaken
That is closed cell polyurethane foam. Polystyrene foam melts on contact with polyester resin. Again you can't use CSM Fibreglass with epoxy resin so it's highly likely to be polyurethane foam
@@gsizzla6734 any idea on the foam density?
looks like the same stuff as roofing insulation for flat roofs
@@gsizzla6734 BS, I use epoxy with CSM all the time without issues.
Hi, I have Campion Explorer 622 WA and would like to remove old stringers and put some new ones. But I dont know how to remove the upper part of the boat from the hull.
And I dont know the exact measures for stringers. Any advice?
Capt Mike, what kind of transducer are you going to use? Glass in a through hull or transom mount?
I wonder if those stringers are laying directly on the hull?
Mike, how do the cut the stringers down to a uniform height and get it even so the floor will be flat? Thanks
What foam is that you are using
Dude, I'm so excited for you! This will be an awesome boat!
The forward bait tank. Won't the bait get pounded in the bow with rough sea's bruising them up or killing them more than a stern tank? I know everything is a compromise just asking.
Hopefully, it will be a pressurized bait well.

I was cringing a little..... I read the owner reply to somone and seemed to be reasonably cool about taking criticism.
Can't wait to see!
What did you use to glue the foam board stringers together and to the hull before fiberglassing? (The dark stuff)
just tabbed in with some glass and resin, once it kicks off the panels won't move. Similar to an "L Bracket" sort of
Awesome boat you’re putting together Captain Mike
That’s definitely a boat worth building, I can’t wait to see how it comes out !!!
Thanks for uploading this build process 👍.

Sweet boat build I'm redoing a 23 sratos from the hull up
How many layers of fiberglass was on the initial fell coat to hull lay up?
why 1 coat red resin and now white resin?
Awesome 👏
Weight of dry hull only? Expected miles per gallon with single 300 outboard?
Total layers for boat hull, please?? breakdown of amount and type
Hey..What material is the stringers made out of?
Air compressor the glass right into your body,ouch otherwise great video
This is great stuff!
Amazing series
what fiber board are they using for the stringers, is the construction fiberglass insulation board for roof insulation
Poly Isocyanuarate aka roof insulation
Hi what type of foam was used on the stringer and where can I buy it from
Did you ever find out I’m interested as well
No wood used in boat building these days is like when businesses state that they have flat screen tv's.
There’s cardboard tho...

Anyone know what type of foam boards they use to fabricate the stringers?

Amazing what a great looking boat. Even naked
This place needs a CNC
I can't believe they're using a handsaw!?!?.........I mean I know they're "hand built" but geeez
At least some electric scissors
Yep, thats what i was thinking. A cnc waterjet cutter would make that so much easier and precise.
@@andrewh.8848 wouldn't want to use water on foam you intend to fiberglass anytime soon, a large cnc router setup would be perfect
Or at least some wood templates with a flush trim router.. very inefficient processes they have. Dont even use a gun to spray the resin..
Biutiful,good👍👍
I didn't hear it mentioned nor read it in the comments but, why the $27?
Hul #27 they built
Is no one gna mention the cardboard paper on the out side the foam? What do experts think of this?
it;s actually not cardboard it's fiberglass
