Seahawk 4 Boat Floor DIY

Seahawk 4 Inflatable Boat Floor DIY. In this video I show you how to make a DIY boat floor for an inflatable boat. The boat that I am making the floor for is an Intex Seahawk 4. My DIY boat floor is made from OSB “plywood” and is covered with indoor outdoor carpet.
This Seahawk 4 boat floor build can be made in a few hours. My boat floor design is a two piece carpeted design that uses no staples. I used 3M Super 77 Adhesive to glue the carpet to the boat floor.
Project Supply List:
1- 4x8 sheet 19/32 OSB “Plywood”
1- 6x8 Roll Indoor-outdoor carpet
2- Cans 3M Super 77 Adhesive
4- swimming pool noodles
1- 28”x24” Piece dry erase board
4- 1/2” plywood clips

I really like how this floor turned out for this inflatable boat! I can’t wait to hear what you think about it. Let me know your thoughts in the comments below⤵️ I am finishing up the video for the motor mount review and will publish it very soon.

[@nancyrice5014]

This must be more comfortable that just the regular bottom. Great DIF!

[@jwhite8953]

This video is EXACTLY what I was looking for! Thank you so much for sharing!

[@MrFredsDIY]

Awesome! I’ll be filming a few more videos with this boat this spring for sure!

[@narendrareddy8763]

Thank you Fred

[@nickacree9669]

Great idea

[@Falthan]

Great instruction

[@Prankshots518]

Amazing

[@PCPAyLOAD]

Great idea flipping the boat over to and using cheap plastic for your template! Definitely going that route. Thanks!

[@MrFredsDIY]

Good luck with your project!

[@MarkMayhew]

Good video thanks

[@aminajdadi3764]

You are awesome thank you so much for teach me and I love you. I am very enjoyed the video.🙏💕🌹

[@chrislo914]

Great video !

[@Moeajl]

Gracias por el video buen trabajo tengo una pregunta para usted estoy para comprar una barca de la misma marca pero el 2 es buena para ir a la playa ? Gracias por responder

[@PhanOT11]

Great video, I like it! I have the Intex Excursion. It’s been folded up in the storage. I’m going to make mine like yours. 😊

[@user-nz2gm5ly7z]

Thanks for share this video. Congrats from Brasil. I am modifing my intex instaling deck and a Sail Kit.

[@MrFredsDIY]

After the new year I will make another video with this boat!

[@MarcBossYT]

Cool! That’s also good if your fishing you can cast a lot better because the ground isn’t squishy! Really cool mod

[@MrFredsDIY]

I’m a pretty big guy and this thing was pretty sturdy. The plywood clips will make it even better. Thanks for watching!

[@chechochecho3934]

¡genial!

[@RajAdh]

nice, make a box for battery as well.

[@Jolab15]

Thanks for this video, very well done and you saved me a lot of time figuring out the best way to make a floor for our Seahawk 4. It turned a potential over a week project into a weekend success.

[@MrFredsDIY]

These little boats are a lot of fun!

[@dachinjo2119]

​@@MrFredsDIYWhat is the size of the floor board? Width and length. Thanks for your reply.

[@MrFredsDIY]

@dachinjo2119 At 3:25 you will find the exact dimensions. Thanks for the question!

[@dachinjo2119]

@@MrFredsDIY Thank you, friend. Greetings from Serbia.

[@aam3080]

Very well made 👍🏼😬

[@MrFredsDIY]

With a few adjustments I think this floor will be great. Next week’s video is all about the motor mount, thanks for watching!

[@ace21edm57]

Nine years ago, my first mariner 3 , I used OSB....you will find it absorbs any water that gets into boat, and then , the osb swells and stays, damp and heavy. The savings you gained by using OSB will ultimately cost more in weight and wood rot over time...Jus saying.

[@jamierichards925]

Even if you waterproof it? Just curious as I’ll be building my own for a excursion 5

[@DogofW0r]

Agreed. I would consider waterproofing the wood and then add the carpet. Or better yet, use a vinyl or neoprene wrap. Repels water and makes it easy to hose off any sand or grime.

[@peterstarck564]

Use pressure treated/marine plywood. Already water proof.

[@tonywells4283]

Do you have any better suggestions?

[@Dont_recomend_channel_button]

​@peterstarck564 wouldn't the floor cost more than the boat then? I can't seem to find any marine grade playwood for less than 400$ here.

[@platinumk]

Perhaps better to use a single piece of carpet and use the carpet as hinges? That way the 2 piece ls are foldable and harder to come apart when unfolded.

[@tyronerice2273]

Thanks for the video... Very well planned out. Nice detailing the steps. I’m a new subscriber to your channel.. Thanks again..👍😉

[@MrFredsDIY]

Welcome to the channel and thanks for watching! I’ve made a few videos for this boat and there are a few more in the works!

[@strickingJAH]

Excellent job thank you! for me I have hard time to be convinced about carpet and water 💧 🙄 😮😊 after few trip carpet rot smell crap srink so on nnnnno carpet please 🙏 😊

[@jmann1487]

Instead of wood, would XPE work? That way it could just be cut to size and then easily rolled up for transport. The goal is that if the bottom hits a rock and starts to deflate, I can last the rest of the ride. (Lowest class of rapids)

[@dylanharding9126]

Crazy the price of a sheet of plywood now

[@MrFredsDIY]

And those prices don’t seem to be coming down either!

[@rickdogg3249]

Hey so for anyone that’s tried it how much did it cost? I’m waiting to do it until I have some money saved up

[@MrLore68]

greetings from Italy and thanks for the idea, I have the same model in my garage, i have never thought about making a floor for it, I'll definitely try it! Should be used chemically treated plywood to avoid fast decay i think... Lorenzo

[@MrFredsDIY]

Good luck with your project boat! These little boats are pretty useful!

[@funnitoni]

Could you have added small hinges and made it foldable???

[@Xtrmn8r123321]

I don't know why, but I keep thinking Kane is voicing this video. I never knew Kane was such a woodworker haha.

[@kevinmencer3782]

Maybe some pool noodles on the joints to reinforce the weak point.

[@fryncyaryorvjink2140]

Besides fitting in a car, is there any advantage to making the floor 2 pieces? And do you think a 1 piece floor would much stiffer than 2 or not really since it's on an air cushion on a lake? Thanks!

[@MrFredsDIY]

A one piece floor is definitely more sturdy! I had a one piece floor in a previous project and found it to be superior. That being said, one of the build parameters for THIS project was to craft a floor that would fit in a car or SUV and still perform satisfactorily on the water. I feel as though this two piece floor design checks both of those boxes. I am 6’ 6” tall & 225lbs and this floor system works just fine. It also takes less storage space in my garage.

[@fryncyaryorvjink2140]

@@MrFredsDIY I'll probably go there 2 piece way then, if I want to stiffen it up more I should be able to do it with a long pipe or two that can be be installed with at least 2 brackets per floor

[@deedeeolive5111]

I love this video! I'm going to try in tomorrow! However, I'm a little iffy on the carpet due to mildew. Would that be an issue, you think? And is that plywood waterproof?

[@MrFredsDIY]

Those are legitimate concerns. The carpet that I picked up from Home Depot is indoor outdoor and is basically plastic so I have not had an issue with mildew. as far as the OSB sheeting (plywood), it is not waterproof but spraying the glue on there definitely provides a waterproofing effect to some degree. This is the second time that I have built this boat. my first Seahawk was about seven years ago and I had that vote for three or four years with absolutely no problems with the sheeting. It will not last forever, but it is affordable enough if I have to someday. Good luck with your project!

[@allans7281]

Yeah the floor makes a huge difference especially when you bring your dog on board I found you don’t even need the noodles it’s just the floor tucks right into the inner chamber and it’s not going anywhere

[@MrFredsDIY]

I find the floor very useful as well. I mostly use the noodle at the rear of the boat. The space between the chambers back there is pretty big and if I step on that area the floor pushes down.

[@sandramckinlay3424]

If I did I would keep the carpet in one piece and make it so it folds right sides together

[@steakdriven]

I own an Intex Explorer 400 I'm wondering if I can do a similar thing with that one. I strongly just like the sensation of my ass sinking into the water so a solid floor would be a great modification

[@MrFredsDIY]

I like being able to stand up! A great benefit of the hard floor too!

[@steakdriven]

@@MrFredsDIY in my case, I'm going to be using the oars

[@doomedjls]

Do you inflate the floor when using the custom wood flooring?

[@MrFredsDIY]

Yes! I have experimented with inflating the floor 1/4, 1/2, 3/4 and fully inflated. It seems to perform best about 3/4 full! Great question!

[@doomedjls]

@@MrFredsDIY Thanks. I bought two of these boats last week but have yet to even get them on the water and the floor mod looks like the first mod to tackle.

[@user-wm6bk3in3h]

what happens though when carpet gets wet

[@bogdanzivkovic157]

How much glue did you used?

[@MrFredsDIY]

I bought two cans but only used 1 1/2. Thanks for watching!

[@makamaka6685]

I had to cut my boat floor in half to fit in my car will it lose stability?

[@MrFredsDIY]

I like the thin piece of dry erase board underneath and the plywood clips. It’s not perfectly stable but it works great!

[@angell6425]

you're adorable

[@davidjerome4689]

Bonjour Quel épaisseur la planche du fond ?

[@MrFredsDIY]

Demandez-vous le plancher ou la planche à l'arrière pour le tableau arrière ?

[@davidjerome4689]

​@@MrFredsDIYle plancher merci

[@MrFredsDIY]

The floor is roughly 13 mm thick.

[@DogofW0r]

19/32" seems flimsy from the video but I've worked 1/2" and it was pretty stinkin' rigid.
