Honestly one of the best DIY-marine content on the Internet.
Thank you!
+Phong Do I agree, and have sent links to friends. :)
+JuhaEerikki Very much appreciated! Thank you :-)
Apart from the music lol
A couple of months after watching this video we discovered a bad leak on our v-berth hatch. I rewatched the video and rebedded/resealed the hatch and glass in an afternoon. It looks great and doesn't leak. Thanks for sharing your skills. You're saving the world from duct tape... :)
Great video Andy! I love all your hints, tips and tricks. Obviously useful for boat work, but many of the techniques you share could be used in so many different applications too. Keep up the good work!!
Hands down, the best boating DIY videos out there. Thanks for your detailed demonstrations.
Your helper did a good job :) I like the hints for caulk, but still a fan of butyl tape myself as long as you can get enough torque to seal it tight.
That is so awesome!! Loved your video and your techniques!! We have ALL the hatches on our boat to reseal...and we finally found the handles online for Goiot Hatches. What a really big pain!! Thank YOU!!
Hi, it's a pleasure to have discovered you ... I see very good craftsmanship and skill, with simple and practical explanations. I have been doing maintenance on my boats for a long time but following you I am sure to learn a lot more. Thanks, good boy!
This is by far one of the best VID I have seen so far.
great videos very informative. I have a classic mako and it's has become a driveway ornament with your videos I'm confident I'll get it back to its former glory thank you
Always learn so much from Andy.
As always, thanks for sharing your skills and tips! I've been avoiding doing this largely because I wasn't sure of the right sealant to use. DOW 795 looks like a good choice!
This stuff can get boring but you somehow make it look so easy even fun. Well done
+John Brookes Thanks John!!
You obviously have a lot of patience. Good job!
After viewing this I used the method on three of the top hatches and 4 side windows on my Amel Mango. They went from leaking to water tight. Brilliant. You saved me thousands in boatyard costs and I had a great sense of accomplishment to boot.
Thank you!
New boat owner to an old Carver. For the most part it is in GREAT shape, but one hatch leaks. THANK YOU!!! I feel I can tackle our leak and stop water from dripping on my face :D without taking another loan for the boat ;)
Great step by step tutorial. Now I know how to seal my leaking hatches. Thank you!
Absolutely excellent explanation AND well planned display of the process thank you very very much
Thanks for the clear explanation. I have to do two leaking hatches of the sailboat we recently bought, and now know how to do it. Regards Sander van der Voort from the Netherlands.
Very nice clean method ! Thank you very much for all these tips !
A joy to watch, well done!
Thank you for sharing your work . I find it very useful.
Excellent skilled work.
Dude, thank you for taking the time to make this video. This was such a big help...
Great job buddy I love these videos. Cheers
Thumbs up for your reaction to the paper towels sticking to your fingers. 😂
I can imagine how you feel.
Thanks for a great how-to!
I found, wetting your finger allows it to slide along much nicer along the caulking as you smooth it out. It also seemed to make far easier to create the tiny valley in the caulking around the entire frame. Wiping off excess of course.
To be honest, i don't even know how there could be a single thumbs down for this video. Wonderful content. Super helpful.
TheNachotime I'm guessing it might be because of the plinky-plonky ukelele music which seems so popular with yachties and their related channels.
I always love your content and choice of jobs........
very nice job, thanks for sharing.
Lots of good tips!
Excellent video.
Loved it. Thank you.
Always so impressed with the clarity of instruction! great video.
Well done video. Thanks
Thanks for the informative videos. Much appreciated… Keep up the good work
Another great video. Thank you for sharing
This was very helpful. We just bought a boat in need of a little TLC, and I need to rebed a fixed hatch (wait .. then it's not a hatch .. right??) Anyway. I appreciate the great tips you shared. I'm glad I didn't do it last weekend like I was supposed to!
Another great video. Nice tunes too! Helper did a good job :)
Thanks for your video. I realized I have part of this job ahead of me. Luckily, only the compound around the lid, the lid itself is good (according to my experiments)
Excellent!!
Awesome! Thanks!
Thank You 🙏
Love your videos. Very informative.
Thanks Brian!
Thank you.
Very helpful, thank you.
Thank you and hope I laugh as much as I did watching the video as when I try the job.
Couldn't have done this job without this video. I didn't have duct tape, but lots of unauthorized clear silicone from the previous owner. Scrape scrape scrape, scrub scrub scrub.

At 03:40 I’m surprised you didn’t have excess seal on the inside. I was expecting to put some tape inside as well!
Very nice video that helps me much! Thank you sir
Great videos
thanks good stuff, have some to do! cheers
Good video
Try 3M hard rubber squeegee with medium pressure. You will get the Dow 795 to drop down a hair below the frame and acrylic. It will look so much smoother than your finger.
Great!!!
good stuff...you are my boating best friend that i never found....lol
Absolutely great description on how to carry out this work, one think was it Sika black you used to place glass in frame, what was the white to attach the window to deck. thanks
Thats a nice one, tx
Nice video thanks. I should have watched it before I screwed up my first hatch rebuild. Silicone everywhere. Lens not pushed down far enough and not contacting the frame.
Anyway my second, and last, hatch will be done using your great instructions.
A question about removing the yellow tape. When do you do it? after its dry/cured or immediately after its finger wiped?
A suggestion: Cover the ENTIRE Lexan glass with plastic when putting down the tape around the edges. It makes cleanup easier should a bit of caulk fall off the tape when removing (or if the tape brushes against the glass accidentally on removal).
Cool!
Exactly what I needed to see. I have Bomar hatches with cracked plexiglass which needs replacement. I noticed you used Dow 798 for sealing the lens in place, but I could not tell what you used to bed the frame to the deck. Not sure I need to go there, but just in case, I would appreciate knowing what was used. Great job and thank you for sharing.
+Kay McDonald For sealing the poly to the frame I used dow corning 795 (791 would work as well). For sealing the hatch to the deck of the boat I used 3M 4000UV :-) Hope this helps!
this was a lot of help for us! We have a 320 and are fixing it up ourselves ;-) first step? leaky hatches hahaha
clean
As always - good presentation and good information - I would like to see the materials used if possible..? thanks much!
I love your videos and they have helped me out. I watched this one to help me re-bed my hatches. Sadly, when I pulled 1, I discovered that the opening was cut by a drunken sailor and in some places a full quarter in. from the framing of the hatch. A couple of the screws were screwed essentially into silicon and nothing else. How would you recommend extending that edging so I have some meat to scew into.
Great video, glad I found your website. Did you put the handles/locks on inside out so you could handle the acrylic easier when installing into the 795? Does that give you more control?
When you bedded the acrylic in the frame you mentioned getting enough Dow so it filled the channel. I assume some oozed out over the edge (I know it will when i do it). How did you clean up that edge which will show inside the boat? Love your channel!
Excellent video! is the bed sealant (White) a polysulfide? Also, do most hatches have the type where you seal both under and above the plexiglass?
Video still holds up. Your daughter is a future star...
Hi Champ and thanks for a new video! :)
I need to redo my leaking portholes and fixed deck windows on my Beneteau Oceanis 430.
I wanted to ask about the VHB tape or equivalent for mounting polycarbonate port windows, re your older video.
Im currently in Malaysia and the 3M VHB tape is not available here. Can you think of any alternative to the 3m VHB tape?
"Scotch 3M Exterior Mounting Tape Super Strong"?
"Kips DIY Grey Shear Strength Double Sided Acrylic Foam Tape"?
The only function of the VHB tape is adhesion, right? Nothing to do with sealing and watertightness?
Cheers
try using windex. the original version. Apply bead of silicone. Spray with windex. Wipe of or tool excess. The windex will repel the ooze and leave the silicone nice and shiney. We use it on stone and aluminum and it really makes you like a superstar
Great video, but you did not show or mention the gasket? I am doing some old lewmars, and I am going to go through the same process, but install the gasket before the 1st corning layer of corning 795.
Great job...i'm about to do the same in my boat Just i want use the Bostik ms pro seal whitch seems to me very good as i used on other seal Jobs. Do you line anything about it?
Also i have question: when you place glass on frame the exess patty that came out on the bottom has to be clean? Haven't seen you cleaning!
Keep going like that mate.
Thanks from Sardinia
Hey Andy, I am working on a fixed portlight, with Aluminum frames. Like the ones in the back ground of this video. The Aluminum frames are like a clam shell around the Plexi, what kind of sealant would you recommend for this? 795? I didn't take it apart and clean it so have no idea how the previous owner had it.. It came to me in pieces. What a dream right.. would love if you made a video of that, you have videos of the other style without frames and now these hatches.. What you say? But any help is great coming from you... I've learned alot from your videos..Thanks
1:52 old masking tape is pretty bad too , great vid mate !
Working in the aircraft industry we used lollypop sticks to smooth it, much more consistent and less "messy" finish!
A lollypop stick or a popsicle stick?
Tongue depressors work good too.
I noticed you did not replace the rubber seal/gasket, if you had what would you have used? where would you have purchased it?
Very informative and helpful video. I noticed you also had the side windows pulled from that boat. I have an older Searay with those same side windows, which I'd like to take care of as well. Did you happen to do a video on how you did the side windows?
Great video.. what caulk do I use around the outside base of my console...on my 26 Regulator. Thanks
water and soap in your finger make a batter looking and result! Try it
Before laying down the inner bead of sealant in the frame, did you tape it off so that when the glass was laid in, and the sealant was squeezed out, it wouldn't make a huge mess?
Hello. Very interesting. My hatches are different, so looking for the best way to get them not to leak. I have a Catalac 8M catamaran. The hatches are more like a shallow box lid (hatch top) that just closes over the bottom which is standing up an inch or so. The problem is that I can't find the right kind of hatch foam/seal to build up enough material to seal water tight. Any ideas would be greatly appreciated.
have you have used butle live rubber what we use on campers sealing . never leaks and it always stays alive even in cold cilments down side it can leave the black streaking.
Andy, I saw in this video that you pulled the side windows as well. I have a similar boat with leaking side windows. Do you have a video of these windows being rebuilt?
Great video, one question what product did you used?
Hey Andy, great content. Very much appreciated. I was curious why you didn't use butyl tape. Is this not a good application for that?
Was wondering the same.
Can you use the DOW 795 on GLASS (not poly) for a windshield? Recommended?
What material did you use at each step?
Andy, can you do a video on resealing the port lights and preserving the seals. I can't find the rubber gaskets that seal my windows and they leak like crazy. Thanks so much.
I am curious Andy... why did you select silicon over butyl tape for this application?
Ok papa... 💙👍👍😀😀
What sealant do you use for the acrylic and the frame.
Dow 795 ..... Yes Sir as good as it gets !
Hi, I have screwed on 6mm plexiglass windows on my sailboat that will be replaced. Would it be possible to only use vhb tape and Sikaflex instead of screws? Love your shows. Thanks Cris
Great video!. Not sure if this is allowed here but we can make any replacement hatch lens one would need. Cesany Plastics, Inc. Cheers.
This taught me a better technique for how to remove the excess sealant.
Great videos... Congrats. One question though... Why did you opt for bedding compound instead of Butyl tape? I find butyl much easier to deal with. Thanks again, keep doing what you are doing!
It may be a little easier to handle, but I haven't had very good results using butyl tape. A lot of people really like it, but I tend to get more consistent results using caulking.. Either one will work, though :-)
What sealant do you recommend??
What if the handles to lock it are leaking? Can they be replaced or at this point is better hetting a new hatch?
You used 2 different silicones, a black (commercial?) Between the glass and aluminium frame, what was the white one?
Great video and thanks! The black gasket that seals the hatch when you close it. It seems on a few of my hatches that has shrunk and is pulling away from the frame. When I spray the boat from above, water gets in. What's the best approach for getting that back in place?
+Timothy McGee Try replacing the old gasket with a neoprene 'D' gasket in the appropriate width and thickness :-) It's a fairly universal gasket that will work on most hatches
