25000 Subscribers / / Mods don't get any bigger than this - Catamaran Project Ep301

If you think I have tackled some big modifications in this project then you may be surprised to see that this week's video has the start biggest project of all, an extreme Bow modification on both bows, at the same time. This is absolutely HUGE !
This KZbin build series is all about what it takes to build a Catamaran from Scratch. There is so much detail in a build of this size and so many different techniques involved in bringing her to fruition. I trust you will find something that may help with your current or future project, repair or dream boat build. If you feel there is value, please let us know and comment so we can continue to produce content worth your valuable time.

Merry merry Christmas >>>if the admirals cough continues it should be cheeked as for the mind boggling captain well i watch you to SE what is next boom here we go bow has a problem Heavy I thought the sugar scoops were Genius and here we go awesome mate

[@cappywa]

Bowlbus bows. You'll need 1 tone of buoyancy per hull to stop the poor-passing on this size vessel.

[@LifeOnTheHulls]

I was concerned about that, but the previous boat had three goes at rectifying, the final solution was pretty smooth.There is loads of secondary buoyancy it was the primary that was the problem.The stern additions were also taken into account by Oceanic Yacht Design Marine Architects to improve the laminar flow.The tulip design reduces pitching but time will tell and can be added or shaved back to fine tune in subsequent haul outs.

[@lkirkby3]

Your ability to modify and redesign almost on the fly is ourstanding. Your customization is going to make this a much more successful craft.

[@LifeOnTheHulls]

Cheers , all good fun, chopping and shunting.

[@darrylellison4933]

Great work, the boat would have looked awesome with forward inverted wave piercing bows. slight increase in hull length, and would balance the additions to the stern. plus look shit hot

[@nickcooper14]

Woo who, you should have a 100k subs mate. Nearly done with the internal fibreglassing. The dinette looks great. Keep away from sika for sealing the hatches. We were redoing ours every 3-6months. Switched to Fixtec and 12 months later not a drop🎉🎉. Merry Christmas to the Life on the Hulls Crew🎄🎄🎄🎄🇦🇺

[@LifeOnTheHulls]

Thanks Nick, merry Christmas to you and yours as well. We will use the fixtech 200 for sure.

[@christophermitchell8986]

Question as it pertains to the buoyancy, when you started building the boat you mentioned this issue and decided to use foam core. You had mentioned this construction method would make the boat lighter and decrease the displacement. My question is - what is the displacement of the foam cored boat vs the chopper glass boat and how will the fore and aft mods change the bouncy?

[@johnwgibson24]

Merry Xmas

[@LifeOnTheHulls]

We have not,and will never spray epoxy, there is simply no application for spraying epoxy that would be used in this build, so not sure what you are talking about.

[@lateralthinking86]

I knew you would do a bow modification but if you going to all that work why no going for the increase on water line it will help the performance of the boat big time and make the boat look more modern.

Never ceases to amaze me how you are such a master at sculpturing the fiber glass. You are never afraid to grind off the Gel coat And change things. I have always wondered when you spot in the new flow coat if you Can do it without getting a shadow line at the blend? I have always seen people struggle with that.

A lot of thought has obviously gone into the bow mods . Well done and happy Christmas to you Janet and crew.

Merry Christmas Ross and Janet!!! Congratulations on the 25K subs! Been with ya since you had 500 subs or so.

[@nelsonclarke7912]

Turn the boat into sleek reverse bows not bulbs!

[@LifeOnTheHulls]

There is no option for us, the rake to deep and boat must stay under 13mtrs for us to avoid excessive insurance and marina fees. Also very difficult to determine the buoyancy required with the reverse bows as we have a known quatity this way. Boat is older vintage would not quite suit the reverse look,Faired in bow will be underwater similar to crowther tulip shape.Ross

[@glasmannschaefer]

Great to see the progress and merry Christmas from Germany.

Exciting times for us viewers with the bow mods😍 I like your solution as it seems far better integrated than the tubes you showed. Of course if the buoyancy isn’t enough you can just trim off part of the stern😁😁 Merry Christmas to you both🧑‍🎄🎅

[@bin_chicken80]

Congrats for 25K Rosco. Merry Christmas and New Year to you and your family! 👍

[@gregrichards468]

Hi mate, loving your videos, my simson cat had extra bouncy add to her the same as you are doing ,one of the issues i had was cracking at the bulk heads when it was lifted in travel lifts due to the foam compressing and not enougth layers of glass, i can only recomend adding a lot of extra glass around the lift areas to over come this .the other problem is the bow will become heavy due to the two hull in that area so if you can lighten up the orignial hull it can help. Also i would not seal under your anchor windlass as it will not drain any water away that comes in through the shafts.Merry christmas to every one

[@LupusMechanicus]

Ya that's going to be a nice crash bulkhead as well. Good luck getting that to all fit together, easy Merry Christmas.

Merry Christmas to you and Janet and the family. Congratulations on 25k subs. You should have many more than that! Have you known about the buoyancy issue for a while? I don’t remember hearing about it previously.

[@ross82]

Can’t help but think a vertical bow would of brought the effective lift further forward…. But as always, your solution always looks like it’s meant to be.

[@rolandtb3]

Congrats on 25k. Finishing some odd jobs. Getting ready to modify the bow to get more lift. Janet get well. Rosco needs someone to check-up on the quality of his work.

[@aserta]

Excellent mod for the issues the boat had and indeed it was a big issue. Did some google-fu after the last episode, on the parent boat. I must've missed the one where you explained things, because like Gandalf, i had no memory of it - i was doing the face too. :))

[@dc1544]

I guess I have to see it when it's done. Looks like you just destroyed how it cuts through the water. will be interesting to see how it sail regardless.

[@LifeOnTheHulls]

We thought the same, we have partly adopted a s.w.a.t.h design(google it) and appropriately designed by the previous builder as boat was nose heavy so did not slice in fact quite the opposite.Extra buoyancy actually is torpedo shaped with minimal resistance on the nose.cheers mate

[@DRB68]

Yeah I expect she is now a motor boat with sails

[@dc1544]

@@LifeOnTheHulls Nose heavy? So did the last owner have his chain extra sails water tanks all up front? every boat can get out of balance. I still have to see yours sail and if it can even reach 10 knots now.

[@LifeOnTheHulls]

We have implemented a bow similar to Top Gun, the fastest cat in Australia.She has a faired in bulb, tulip shaped, all of lock crowthers designs pre catana were built this way too, there were very little performance issues there also.We opted for safety and piece of mind that can be adjusted after trial period.Always a compromise.

[@LifeOnTheHulls]

Previous oener had it fully rigged, sat 40cm nose heavy, bow was too fine designer walked and left him with a 150000 debt.

[@svdirectorspecial]

It’s all coming together now Ross , do you have a launch date in mind, have you started planning the mast and rigging yet

[@davewilliams639]

This is pretty intense boat building. Where did you learn to do this technical stuff?

[@gregoryh4601]

Merry Christmas to You and Wifely and family. Would going with Carbon Fiber Mast and Dyneema Rigging also Help out the Weight and help the flotation?

[@stephenj9563]

Good episode Ross (Back to watching on the laptop) Did you consider getting a naval architect involved with the bow mods? The interior is starting to come up really well, can't wait to see all that tape and paper come off And merry Christmas to you and Janet

[@LifeOnTheHulls]

There was a naval architect involved in the last boat.I have simply followed the lead, reduced the diving forces and increased the buoyancy in the tulip shape.This is totally adaptable after sea trial or an extended period of testing as we can shave ,add or alter quite easily with this design.Cheers mate, happy Christmas. Ross

[@stephenj9563]

I ran into Ron at Boatworks and said hi Did you know he rescued a couple of young blokes who capsized fishing off Curtis Island?

[@LifeOnTheHulls]

Yes I spoke to him that afternoon, the boys were so lucky , amazing situation.

[@richardmondor1360]

Very cool modification to the bow!! Question, why didnt you just take the bow to a vertical or even a leading lower swept forward line instead of that swept back one?

[@tomvanrooyen3600]

Happy Christmas to you and your family. Question. With the extention is the cat still a 40 Footer? Love it.

[@gavinferguson]

congrats on 25k idid think about the bow and wondered if you would go for a reverse bow even siling wilda did there a year ago il like that look and the benefits for buoyancy are good any happy new year and holidays to you and family

[@billmccaffrey1977]

What calculations did you make to know how much lift you needed and provided with the bow mod? Did the boat manufacturer help you any?

[@LifeOnTheHulls]

Yes mate, the previous boat was solved and floatation established with some effort and cost to the owner of the vessel.I will likely make minor adjustments on first haul out after rigging and thorough testing.Was never going to be perfect.

[@billmccaffrey1977]

I know fixing these sorts of issues can be damned hard after the fact, because you are limited in what you can do. I have modified other peoples designs before without having access to their models and data and it was hard. I'm glad you had someone else go through this problem first so you had a starting point. I have one more boat in me at 67, but can't decide what I want to build. @@LifeOnTheHulls

[@78sgr]

Hey Ross,would raptor be good for the locker?

[@latitudeash]

I would put a reverse modern bow on it, your modifications have to be done so why not make it look modern also? Anycase you know what you’re doing.

[@LifeOnTheHulls]

Modern does not always solve a problem.Reserve buoyancy and under 13 Mtrs is the dilemma.Marina costs, service costs and plunging bows are major issues when extended bows are implemented for nothing other than cosmetic appeal.

[@noname-nd8ec]

If you want some real buoyancy you should fill it up with helium, then you would have as catamazeppelin

[@LifeOnTheHulls]

I already have a high voice from all the straining this week.

[@seancasey2444]

What about the ceilings how come you didn't spray them to.

[@LifeOnTheHulls]

Sean, we will be installing upholsterd liners on most of the ceilings for softness.Cheers Ross

[@lockie3075]

I hope you made two of each station and copied it flipped it 180 or mirrored it for the other hull before filling with foam. I can't wait to see the results in the upcoming videos. Thanks for all the hard work making such interesting videos.

[@LifeOnTheHulls]

Yep mate, all under control,

[@Cameron-ur2tk]

I believe the bow modification is about as good as it gets given you have to add it. I remember you touching on that bow heavy topic and also changing the construction to foam core to help lighten the build. There is a KZbinr "sailing frenchman" who has some incredible sailing footage from competing in the clipper racing around the world in a genuine race boat and also crossing oceans in "regular" boats. I mention him because he had/has this little 8-10m boat that has the wildest the hull shape ive seen in which he races (whatever you do to your boat it cant be as strange). Ill link the weird hull video but definitely take a look at his other videos at the clipper race if you have some time between sanding. kzbin.info/www/bejne/Y3iznpKrmc12rMk
