THE NEW ODISEA 48 - A performance catamaran like no other - Naval Architect tells ALL 

Peter I think I may speak for all of us, we're so EXCITED to see this boat come to life!!

While your narrow beam/low volume stern shapes do give low drag, there is a problem that should be considered and addressed. There is an old warning that goes way back: "Beware long narrow double enders". Wide beam/high volume sterns make for nice aft cabins, but there is another reason to have them. The problem is the pitching of the boat matching the wave action or "rate of encounter". Consider the pitching of the boat as similar to a pendulum. If the boat is encountering waves at a rate that is the same as the pitching time a resonance can occur that results in extreme pitching or "hobby horsing". This will more likely occur going up wind as the as the wave frequency or "rate of encounter" is more likely to match the pitching "moment" of the boat. If the shape of the "immersion curve" of the bow and stern is the same, or symmetrical, then the boat can act as a pendulum and pitch can increase to extreme amounts, or "resonate". The effect of having different volumes of bow and stern is to make the resonant frequency of the bow different than the stern. This asymmetry means that one wave "rate of encounter" will excite the bow pitching resonance and a different rate will excite the stern. Since only half the boat is trying to "hobby horse" at a given wave rate, this results in a reduction, or "damping" of the pitching motion. The asymmetry is mostly influenced by the stern's above water shape. You can still have a nicely tapered hull shape below the water line, but having the above water flare of the stern too similar to the bow can invite this problem. At the other extreme, having the sterns too fat can result in excessive lifting of the stern when surfing down a wave and burying the bows and "stuffing" or even "pitch poling'. Like so many things in life this requires careful compromise. More is not better. It's good to have the sterns sink into the wave some when pushed from behind. Having the sails up can provide some pitch damping. More when trimmed for reaching than close hauled. I have watched several early design catamarans exhibit severe pitching resonance when motoring out of the harbor breakwater and encountering ocean swells with their sails down. They had very similar bow and stern shapes. Another way to achieve pitch damping is a horizontal T foil on the rudder. As used on Rapido and others. Loads from this can make kick up rudder design more challenging. T foil also works at anchor and can improve comfort. I wish you success with this project.

Wow , been watching your YT journey from the start ,, this is an amazing story of tenacity ,, good on you Peter ,, so happy for you ,, can’t wait to see your dream come true to fruition

The new boat looks amazing but most importantly as safe as it's possible for a vessel, cant wait to see it and you using it. Looks good news for the boat builders also as I'm sure a lot of people are going to be interested in purchasing such a boat. Well done the whole team.👌

Brilliant. Good to hear a marine architect talk only about safety and Hull characteristics rather than interior design, 5 layout options & finishings

Proof it were needed that 'Good things come to those who wait !'

Absolutely amazing presentation, and design. Top stuff Peter and Marco!

Hmm, the boat has everything I want in a Catamaran. Way to go Gent's. Very Happy for you Peter and ODC is top notch.

Looking good, Peter. You deserve a good vessel. You are such a fun guy.

Congratulations plukky she is definitely a beautiful catamaran 🐬🌊 I hope it comes with gorgeous crew for you. 🐬👍🍕🏆🏖

Wow! Lots of exciting new features on this build. Can't wait to see one in person!

Peter, how will you survive such a nice boat?? You won't be able to be your normal self, everything will work, the lighting will be efficient, the wiring won't have been fried by lightning, there will be an operational refrigerator, surely there's lots of pineapple storage space... What will you do??? Seriously, it looks like a gorgeous design and you deserve to be the captain of such a fine craft. Looking forward to the launch. I hope Lisa is watching.

Top work Pluckster ! How life changes.

I'm watching this interview like the 5th time already. When I'm watching other channels splashing out their life savings, plus money they don't yet have on fantasy plastic tubs like HH, Outremer, Balance, Seawind, Lagoon, FP, Leopard etc, I have to say in comparison to those, this Odisea 48 is the most sensible new boat to come to market.

I'm even watching all of the adverts for you buddy, so stoked for you!

Very nice , can hardly wait to see the completed ship

Excellent presentation. Excitedly waiting for the build…good stuff

This is so exciting. I can NOT WAIT to see your first sail on this amazing new boat! Kick-up rudder feature and the dagger boards is great! Wonderful design considerations all-around.

I can't wait to watch this project start to take shape Plukky. Long time coming.

I am so happy for you. And I am so looking forward to new adventures and a hot crew.

Cannot wait to hear more updates. Good luck on the build.

It's awesome to get this design walk thru to better understand the end goal, thank you for doing this!

This is the content we've been waiting for.

The length of those rudder posts in the original breakaway design and the load put on that block and plug look like a failure waiting to happen. This looks like a great design with low drag. I am very interested to see what you do for propulsion (besides the wind). So happy it's happening finally. Thanks for this Peter.

Great update! Thank you!

I’m impressed Pluky, I’ll take one😅 lots of thought have gone into this and I can’t wait to see it come to life.

Looking forward to seeing the build progress!

Good stuff Plukky. Was so looking forward to the engineering talks!

Top stuff Pete. Very excited

The new boat looks amazing can't wait to see you using it. Looking for your future videos focusing of building the boat!

Totally can't wait to see the build!

Awesome, you are going to be flying over the water!

Yes keep up the pictures & discussion of this build ! 👍👍

Brilliant Peter. These vids are important. It’s giving everyone a look into the amount of work time and dedication going into this project and also a sense of inclusion right up until she kisses the salt for the first time. 👍👍👍👍👍👍👌👌👌👌👌

Excellent video i really can't wait for the build start

Congratulations to infinity, Plukky and Odisea crew. Well done. It's getting real now. :o))

Thanks, Peter, looking forward to more of this.

Yay! Alloy is awesome! So excited for you!! ❤

OMFNG! This is an amazing project and an amazing structure.

Looks awesome- good luck Peter

Competiton is always good, competing for the best design. No doubt this will be exciting for all to watch. Good luck Plukky !!

👍🏼Outstanding design!👍🏼 Really like the new modifications, can't wait to see her start to go together! Take good care!

This is an amazing video! Thank you for sharing ❤

Excellent discussion, excellent boat.

Very well planned and designed, our boat is gonna be a ripper Plukky!!!

This is looking pretty amazing Plukky.

This is so exciting! 👍🏻👍🏻

Looking forward to it Plukky!

This is going to be a fantastic build, your video production skills are bonsa .... I can't imagine this channel not becoming the most watched on YT.....

The boat looks awesome!

Amazing can't wait to see this thing.

Awesome presentation Peter of your new up coming vessel ..very sleek profile...hopefully we'll hear more about power, generator, battery and electronic systems that will be utilized for this boat soon. Cheers 🍻

Good on you, Peter. Marco provided sense and substance.

I'm so happy that you're getting a new catamaran. I know you love cats' and I hated seeing you lose your first cat'. but at least you still have the memories of it and memories of some of the first crew like the Italian, Fedra. 😛

Amazing design, looks like a Top Dog. Can hardly wait too see it come too life. CHEERS TEAM SAFE TRAVELS Steve h.

so cool! Excited for this!

WOW what a boat and great idea's. Should last a lifetime

This is going to be awesome boat for you plucky , can't wait to see it...

Love it, Love it, Love it!!!

Really good points about the design, construction and materials. Thanks guys! Really like your practical approach. Tim Mumby's too.

That's awesome insight into the Odyssey

Looking sharp Plukky!

That yacht looks beautiful 😍

A beautiful design!

Congratulations on an awesome design - most all of the issues I have found with existing performance cats have been addressed including 1) no sail drives 2) kick up rudders 3) positive flotation (almost unsinkable) 4) solid stem to handle logs, etc. 5) open air ventilation and 6) low accessible boom.. The one thing I do have on Blue Bamboo is 360 visibility (especially for docking) and great weather protection with the steering station at the center of the boat. Great team work between designer and experienced owner. I am so happy for you Plucky - your dream cat is becoming reality.

Looks amazing!

Top stuff, Peter!

Wow, haven't heard of this company before but very glad I came across this video!

She looks like a beauty, whats even more beautiful is great minds from around the world contributing ideas and experience. Cant wait to see it!

Wow so many aspects of this design are just what’s needed in an Ocean Going Cat fantastic!!❤

Great looking design Peter

Can't wait to see it fly.

Great overview. You can tell that a lot of careful thought has gone into this design in response to a mass of real-world cruising experience (good and bad). I look forward to hearing more and ultimately getting to see how it all works out in reality. Particularly being able to take advantage of that shoal draft capability to get into places others are forced to avoid. And the speed and sea keeping to get to them.

Great job pluk

Good stuff mate, gonna be a beauty. Not sure Marco is cut out to be a super entertaining YT star like yourself, but he seems like exactly the bloke you want designing your boat. Serious guy but he did manage to smile a couple of times...😊

A new home, how exciting for you.

Wishing Peter and Odisea a festive and safe holiday season. :o))

Going to be awesome Peter! Burlington Bill here.

Plukky, well done mate. Now get this cat together and share more adventures with us. Well done bru.

Well done Plukky! Your doin Good! Top Stuff! Goodonya from the Gold Coast Australia 🇦🇺 👍👍🤙🌺🐝⚓️🍄

Nice work

Love that they copied the Balance 526 helm, after 7000 ocean miles this year at the upper and lower helm stations, I can say you've made a great choice & you are going to love it! Definetly a boat the blends to best features of a lot of different cats.

Very informative

If history is any indication those watertight compartments are gonna be key

I have a Schionning Waterline with kickup rudders, the rudder and cassette is the one piece and the sacrificial strap is at the back and can be pulled back into position once released. So far great except if you are using more than about 12° of rudder the trailing edge of the rudder is beyond the limit of the cassette and will catch on the supporting side supports of the transom.

Great video. Extremely well presented and explained. Anxious to see it being built and come together. Love all the safety thought out and applied. We all shall love it and travel with you. Please get proper refrigeration and A/C. While you are at it, have them make "the claw "and patend it, then add it to your website store! Try and put-in a cleaning station.

Top stuff Peter. Very well thought out. Sailing Nahoa has the same focus of building an expedition catamaran in aluminium. Congratulations and I have resubscribed in the hope that you have a logical flow for your future videos! Perhaps you can even include a date in the introduction of each new video? Charles.

Looking forward to this serious

great vid!

Gotta love those watertight compartments - especially for the engines and steering gear!

Freedooommmm!!!! Woo hooo!!! Way to go pluk master plukky!!

I can't wait!!!!

Very nice! 👍

A note on the hatches that Marco mentioned. My experience is that even after more than 20 years the hatches screwed to a flat aluminum frame, which is welded in, do not leak. The leakage problem concerns the windows that open to the front. One step forward is to divide the curved windows into flat segments. This makes reworking easier.

Well done ole mate After 40+ years of sailing, racing, cruising and delivering cats This is one of the best new design cat I've seen Designed to go out and even better .... come home safely Again I say Well Done Peter and the whole team Q. Is there a dollar mark and timeline yet available? If so, include any hint or info in your next clip Till later

Hooley Dooley, hey Plukky . . I do believe that your mob are on a winner.

Ive watched it twice and i cant fault it. I particularly like the low boom not only for its asthetic value but because it has a huge bearing on both stability and drive. I know this from windsurfing. An inch up or down in boom height on a windsurfer utterly changes the boards behavour in whatever conditions. Daggerboards that sheer....bloody marvellous. The rudders are sprung or counterweighted down so in the event of a collision will ride up but go back down into position on their own after the impediment is astern. Well thats my guess anyway so looking forward to the next instalment when all will be revealed hopefully. Wondering if the boards are interchangeable? In any case i think ye have hit the bullseye with this design. Its strong, safe, efficient and easy to maintain. Im so pleased for you.

Good stuff. I'm keen to see the rudder kick up system.

Always knew you would land on your feet even when watching you struggle during covid . There is an energy , a do what is needed drive that separates those that do and those that don't . I don't think it can be taught

Thanks
