So many people would think they could never afford a sailing boat. And nobody would think you could just knock one together in a day or two! Nothing is impossible! I live in Canada and just love watching you create almost anything you need and even the things that are just pure fun!

Next thing might be to add a hydrofoil to the keels ? At first I thought it resembled a craft meant to fly to the moon.Fantastic job,great to pick the fruit of your mind and make tangible the incessant pondering ? Very satisying indeed,I wish the pair of you many happy ventures.

For you it is a prototype, for me, this would be the project of my lifetime! You are so industrious and full of ingenuity! I am in awe.

"Humming in the quiet bits"...you are going to give the BBC a run for their money if you start adding extras like that. Thanks again for a most excellent video and I await more benign sea conditions for your trials. Cheers from Canada.

Sorry, just have to add that the image of you walking with the boat as if you and it were just out for an evening stroll. Brilliantly comedic! I am still smiling

well done Tim. can't wait to see her on the water. A good technique for stitch and glue I learned too late is to drill your screw holes oversize and fill with epoxy, and then re-drill again to create a waterproof fit. In any case thats the weak point I found in my boat, a quick fix us bee keepers can use is the old waxed screws.

What a clever man you are, I live on the Isle of Man and have often thought of building my own boat, you may have just encouraged me to give it a go. Thank you.

I guess you need not more congratulations, you might have tons already!!! But cannot hold my fingers to say I am glad for you, that is what for me is living life!!! Hugs!!

Glad to see scarfing!

Can't wait to watch you sail her....The best to you both.... PS: and what Gary Z said....wrap the mast with fiberglass and resin......

I love building small boats also, and I make it up as I go. Good job. I like your ingenuity.

I really enjoyed watching this video. Great job! Though it was fast it made me feel more comfortable with trying to fiberglass my own hull. I hope it brings you many years of joy. God bless

Beautiful design and you are very handy with your construction methods. I hope to see you enjoying that new version soon. Great work.

Great job! I like how your parallel 'ladder' gives you a sharper V at the front. FWIW, the rudder-keel is a skeg and the triangle at the front is a breasthook. Fibreglassing is much easier if you can tip it over and work one horizontal surface at a time. Also, you can mix microballoons into the fill coat of resin to save weight - then it smooths out really nicely and doesn't need much sanding.

I always enjoy your videos. Both you and your wife are inspiring. Thanks.

Colin Chapman said "add lightness", seems like the perfect ethos for building a catamaran.

The bit that the rudder attaches to is called a skeg. I watch a lot of sailboating videos and they talk about "skeg hung rudders" all the time... : )

never a dull moment with you guys, I really enjoy all your videos. hope she sails well.

I like the use of PVC for a rudder hinge. Who knew it was that easy to heat and manipulate. I might try that for my DIY kayak rudder.

Thanks for sharing with us, I really enjoy watching all you get up to and the way you get round any problems that come along. Best wishes, Christine

A very smart looking job. I cant wait to see you sail it. Kudos Frank

You are so clever to use your resources!

Tim the narration is some of the best parts of your videos.. I have now subscribed.. thanks for the funny videos and lots of great inventions and you never know you might get a gig on the Inventors TV show that we used to watch as kids.. haha..(is it still about?) showing my age now.. some 40+ years ago on ABC TV. BTW I am a wooden boat sailor and maker so I can relate to a lot of this.

I'm amazed at how your mind works. Best of luck and be safe!

You guys are such a pleasure to watch. I wish you were our neighbours. Bit far to South Australia though. Cheers to you both. ☺️☘️

Thanks for sharing. That's a keen bit of boat building. Look for forward to see how it sails.

The worst part of building two of anything is that by the time you've applied all the lessons to the second one, you are liable to build a third because the first one now feels inadequate. Looks like you did a good job avoiding that :)

Well, it started out looking 'a bit Heath-Robinson', but actually it's looking reasonably useful now. Looking forward to seeing the maiden voyage. Good luck! Regards Mark in the UK

Great stuff, glad to see the red sails of your Mirror ( 29220 ) being reused!

This is the guy I want to be marooned with! Which makes me think, the Professor and Skipper really never had any intention or desire to get off the island!

Nice Job, can't wait to see you sail it .

Wonderful. I can hardly wait to see how she sails.

Love joy peace wealth & abundance for all from Thailand .

Oh thankyou so much for this video! I will make sure to come back and show you my iteration on your design!!!

I came to know your channel some time ago from your old boat building video and have been a happy viewer. I like your videos but love your boat videos. They are very original and practical. I look forward to your sailing the new boat very much. If the boat is too heavy you may try adding removable wheels to the skegs or keels, but you've probably already thought about that. I make a lot of videos but do not spend the time to make them half as fun to watch as yours, thanks for making and sharing. Thumbs up.

Hi, very good idea to make it the way you did . I look forward to see her on the water ..

Pommy handly men are crazy.. I love it.

I just had a couple of friends pass away on a catamaran because of a low hanging electrical poll they hit. 😞 I saw this and it reminded me of them.

"At this point I'll be waterproof." Awesome😂

You great and fun to watch. Wel wel done.. 👍👍

What a truly wonderful and inspiring video it's so amazing seeing DIY come to life, it's as if we are learning as we go along with you. And Furthermore we love your house and your workshop. We wished we lived near by so we could build boats together.

Hi friends, we have to wait the second chapter ......no problem ....no anxiety.... jajajja . Juan from Uruguay.

A very interesting video. Takes me back to making the Mirror dinghy, stitch and glue method for my kids in the 50s. I used to tow my Fireball and the Mirror went on top of our Mini. Holiday kit in the Fireball. Those were the days before I left England. I'm waiting to see how your boat performs! All your videos are interesting. You seem to be a hive of knowledge and more importantly, able to turn your hands to anything. Great stuff

I love the fact that you're using a sail from a Mirror Dinghey 11 :P

awesome! can,t wait to see the maiden voyage!

So great!! Waiting to see what comes next!!

I like that you don't claim to be an expert. You are a doer not a talker and that's great. I am like that too. I have done unmanned boats, heli's and planes for years and that taught me quite a bit. I am sort of a concept designer of sorts "unofficially." A few years ago I became obsessed with building a robotic, solar powered water jet catamaran because "CATS" are cool. So a few ideas I have for ya that make glassing i little less hassle.. The 90 degree bends will always cause an air pocket which will be weak and eventually break loose, chip or turn into a hole. The more rounded the 90 bend is (Base of your hull) the less likely you will end up with this issue. I lay one shredded layer down first to spread the cloth wide enough to grab good then while still curing will spray 90 adhesive down to make the boat tacky. That will then hold all of the glass in place for ya and you can dry squeegee it down to shape and contour. Another way is to use a paint roller and wet the entire wood you are working with. You will find if it is wetted out with a roller you will use way less resin and it will also go on quicker and you'll have more time before curing. Overall what you've done is great, especially not being a formal glassing boat shop for sure!! Keep up the great work. We all learn from each other. I'm still getting my KZfaq degree as we speak!

Hi, What an amazing video very impressed , the only thing I would change is the fibreglass that you used its called twill . I would recommend 45 degree biax it's thicker and stronger , and also cheaper . You will use less resin this way so it will also weigh less ...the only down side is its rougher to touch than than the twill , but the epoxy goes off quicker as the glass is thicker . Keep up the good videos.....

I love catamarans!

Thank you for uploading this video Sir it will be a lot of help for me. for one day i will build like this and a little modification. from you i have foundational knowledge in building catamaran un a fastest way.

Fantastic, that came up really good can't wait till I see on the water.

I bet _James Wharram_ would approve...😊

Love you two!

Subscribed cause I like your humor.

That is very cool. I may build one myself.

Excellent build and video. Waiting for the launch. I'm getting ideas for converting my canoe to sails. A little trickier to build, but dagger boards instead of keels would make it more versatile. Considering something like that for my canoe lee boards.

1:20 That alone made me subscribe.

You sound like the guy from the lighthouse in the purge episode of Rick and Morty. Hopefully someone will get this! Or even kind of like the fish "clouse" from American Dad...

Great work Tim!

Just.... WOW!!!!

Very nice project! I want to make something similar this summer, but I think I'll screw several cross sections inside the hulls to give it a more "rounded" shape. I am more worried about its solidity than its weight. ;)

WOW ..GREAT JOB ...

love yall's show...... do more

the nice thing about this type of prototyping is 1 its cheaper and 2 if you get the design down you can strip the completed boat down and use the hulls as bucks to make a fiberglass version. just be sure to gel coat, polish, wax, and add release before using the prototype as a fiberglass mold.

Nice job

one small advise ,aply resin on the plywood before adding the cloth .this way you will get a much better bond between the cloth and the wood

Wrap that broken mast with fiberglass and resin. Use a crisscross pattern of strips. It will be better than new.

Well done!

Really great exllant ..👊👊👊👊

Great video, very nice build, thanks for sharing

@6:01 my next door neighbor tried fiberglas cloth netting and resin like yours on a row boat -- with generous sanding and careful application - and the whole thing peeled away after a few days in a freshwater lake. Yours appears to have fared well!

Love it. I didn’t see you seal the inside, it will get condensation and lead to rot. Also put in a vent fore and aft, obviously close before sailing! Epoxy is great stuff…but please use gloves, it can sensitise your skin. Actually for cheap n cheerful, polyester resin is fine and 1/3 the cost. For the fillets, did you include a fibre, makes them much stronger.

Great video, I laughed out loud a few times, well done!

Very well done

Well done! I think the word you were looking for ('the keel before the rudder') was "skeg."

you are living my dream :)

Well done.

first off, i would like to thank you for this video, innovation putting your idea into practice. if you don't mind my suggestion, instead of using plywood, which can become waterlogged. that means the water will add weight and the plywood will separate in time. why not use linoleum and fill internal with spray foam insulation which will be flexible and lighter. just seal the seams with waterproof sealer. at the bottom of the catamarans, glue with adhesive with thick protective abrasive rubber. my project for my mini-pontoon will be a large mainsail made of the ultra-light parachute material and a small tail triangle sail with the same material as a secondary sail for high wind. operation. both sails will be using mini-pully to ease of up/down hoisting whenever the wind dictates. i will also have a troller and deep cycle battery using solar power to charge the lithium battery. i will put on youtube video once i get it 100% rigged and trial at the nearby river. wear your life vest at all time in case the craft tipped over or man overboard. have a safe watersport.

Humming in the quiet bits, you silly person.

Ha Tim what will you come up with next. Great! I imagined them sound effects they were exceptional :)

your goofy commentary was a good laugh thank you.

i love this man and woman and bob to

My inspiration!

That's so cool! I've built several cedar and cyprus canoes and use west system resin so because it doesn't yellow over time like standard resin. I might have to try a catamaran next.

Can't wait

Great stuff as always!

Your voice is incredibly relaxing to hear. Could you please tell how to estimate the amount of weight the catamaran can take ? One sheet of 1/4th inch thick - 4 feet x 8 feet plywood can weigh 22 pounds. Assuming the human being weighs 170-200 pounds ? How can one estimate the maximum load this can take and not sink ? Thank you -

great video, you are a talented man, btw the part you didn't know the name of (rudder keel you named it) is called a "skeg"

Great video, looking forward to its test sail. Just a few thoughts, I'd have painted the inside with waterproof paint before I put on the decks, and those keels look a bit too big, did you fair the front and rear to make them a bit more hydrodynamic? It looks like the old mast snapped because the grain doesn't run the full length of the mast. Happy (thrifty) sailing RM.

Great boat!!!!

Of course one needs to keep the mast when breaking it was the reason to build a new boat in the first place... makes perfect sense... :p

Bravo!

Have you considered using PVC as a framing material? It's strong and quite lightweight. Also, if you made your "ladder" segments with triangles vs. squares they'd be stronger and possibly lighter.

The "rudder keel" is called the skeg.

You are so clever...

Cool think I’ll base my electric boat on your hulls. I’m surprised you don’t use epoxy

I've watched this before but last time I didn't notice your outfeed on the table saw. Why didn't I think of that last month when I was ripping down that full size 4' x 8' sheet of plywood?

man love your channel!!! One of my subscribers told me to check you out! Great motivation for my homestead build!! Thanks

I think the bit in front of the rudder is called a skeg.

I think you are amazing!
