Lining off the Hull and Installing Ribbands on the Haven 12 1/2, S2-E5

[@marcosrobertojuppa2107]

Another beautiful video! Besides the good explanations, I think that following this project is something very motivating for those who want to build a boat. Let's go to the next one. Congratulations!!

[@amberjackymottie6989]

Thank you very much for you give me much easy careful explanation.I am a Japanese age 60 years man.I have a dream to make small sailing boat,have looking for favorite one.Haven 12 1/2 is just I what I continued looking for.Unfortunately,I have no work space,less money,and no teacher ,no boat builder in japan. In spite of Japan Island surrounded all over sea,wooden boat making is not at all unpopular. I had purchased only "how to build Haven 12 1/2"book from over seas(Oh! re-use from Sweden) and plan sheet PDF(by wooden boat store). I am just on the start line,and for me boat building is so difficult. You give me hope and dream,yes I was able to have dream!

(Roly)...boat builders are artists, thanks from the UK.

Enjoying your videos as I am in the early stages of building the Haven 12 1/2. I am noticing your repeated comments about getting strait lumber and totally agree its very hard. The solution as a cabinet maker of 45 years is to simply make your own true lumber. Buy rough sawn lumber. Joint 1 face and one edge to true. Then thickness the other face true and table saw the other edge true. You now have totally strait and true dimensioned lumber. Thank you for doing these videos. They will be an incredible help to this father, daughter and son team setting out on this build. BTW. I love your sculptures.

Great Production values, never patronising, always clear and concise - a real pleasure to watch, thank you from Scotland

[@martinjancar7398]

Scarfing jig is a life savior for me, honestly... I was trying to come up with something similar for my canoe build. Thank you, Sir. Beside this, I really enjoy the precision and attitude you are showing... looking forward for the next episode...

[@thomasarussellsr]

That jig, if built just right, would make a great shooting board for fine tuning the ends with a hand plane too.

[@YachtHunters]

They really are "sculptures that float".... fantastic work!! Really inspiring stuff!! :)

[@daleskidmore1685]

I love the way moulds look at this stage. There are very few people who go into as much detail as you are, which has been a frustration to my research over the last 3 years. You are filling in some of the gaps. Keep on keeping on.

[@mattevans-koch9353]

If no one gets anything else from this video the scarfing fixture for the chop saw and the way you adjusted the molds for the bevel make this video worth watching at least twice. Excellent work sir and very informative. Thank you so much.

[@thomasarussellsr]

Getting jiggy (ribby) with it. Lines look like it's going to be a wake cutter of a little boat. I see it coming to life. Nicely done, sir.

[@danifem]

Already looks absolutely amazing

[@NickLuker]

I am definitely stealing that scarf joint jig to cut wedges from thinner stock, except I think I'll just make a right-angle jig and slightly rotate my chop saw. I don't have to be as accurate. It also has to be very exciting to reach this point, when the boat starts looking like a boat. Although we can't see it, I hope you are using hearing protection to save your ears during those long ripping and cutting sessions.

[@johnathankaye6747]

You are now my favorite channel. I sail a Bristol 40 yawl and a Cape Dory 25 and love old traditional style boats and this design I also love. Will be tuned in you are wonderful at explaining.

[@tomtruesdale6901]

She is coming right along and looks great. You give just the right amount of information to make it easy to follow but don't get all wrapped up in the tiny details.

[@richardbohlingsr3490]

She looks to have nice lines to her hull. A lot of work but it looks very nice and strong.

[@rt88glow]

Great build series; it's a joy to see the boat come together!

[@hughbugger]

This is so professionally produced, how does this channel only have 1k subscribers. Looking forward to the next episode :D

[@woodpeckerbinojpathrose3068]

Thanks

[@Rsama60]

I have a sailboat (Glasfiber or a we say here a yoghurt cup) I do not plan to built a wooden boat for I have no time and space. But I find those videos so relaxing I will watch them all.

[@saulverdugo4950]

Thanks, Hi! From Baja California Sur, México! 👍🏻 great!

[@mmohon]

We have a maritime museum in our area here in Louisiana, and we have a yearly wood boat festival too. They teach a pirogue building class I want to take one day.

[@davidc6510]

Interesting how the last of the rib bands on the bow are offset on the molds. Why was that Bob? Because of the transition for the keel? Great video and thanks for sharing.

[@SteveHayes1]

You are making fantastic progress!

[@michaelseibert634]

Bob - I was wondering if it would have been an option to scarf two full-sized sheets of plywood together and then saw the ribbands out of the ply. It would have been more difficult to handle the sheets of ply, but wouldn't it have save a lot of time?

[@TheArtofBoatBuilding]

Hi Michael, I didn't use 2 full sheets. 1 sheet and not even a fourth of a second. In fact I only bought one sheet to start and nearly made it. So it never occurred to me to scarf 2 sheets. Thanks for watching Cheers,

[@andysparks7381]

Bob, is the stern knee attached to the transom with just those three brass screws? Is that a high stress point on the boat?

[@TheArtofBoatBuilding]

Hi Andy, Yes, It's attached with the 3 screws. The stern knee is apart of the backbone of the boat. The transom is also supported by all of the planks and the aft deck. The stern knee along with the stern post help to support the rudder. Hope that answers your question. Thanks for watching. Cheers, Bob

[@danifem]

never saw this kind of scarf jig. Only router ones. But this seems way quicker

[@jimjenkins673]

Your channel is great and will explode after the boat show I hope.

[@charles.neuman18]

In terms of spacing out the ribbands, you said you measure and then space the bottom ones out a little more. Beyond that, is there a science to it, or do you mostly use your eye?

[@TheArtofBoatBuilding]

Hi Charles, Yes, lining off is intuitive process relying more on your eye than the measurements. The idea is to get the planks to appear the same. Much more latitude on the bottom as it will be below the waterline and not seen. Thanks for watching. Cheers, Bob

[@jeffreyny2la]

Hello, it seems like with all of the scarfing and ripping of rib bands that that is a more time consuming process than making all 22 stages. Is that not the case? Really loving these videos…

[@Dustmadeout]

Nice job! Could you explain to a non-native English speaker, what is the difference between ribbands and stringers? I'm a little bit confused.

[@TheArtofBoatBuilding]

Ribbands are on the mold and are not a part of the finish boat. Stringer run longitudinal on the inside of the boat as part of the support structure.

[@timreynolds1195]

Looking good! Nice shop too.

[@Cryzgr8]

Bob: I see you trim off the ribands at the bow. Do you do the same on the transom? They looked so fair the way they hit the transom I almost hate to see you trim them off! I guess it only makes sense so that the planks hit the bevel of the transom.

[@TheArtofBoatBuilding]

Hi Cory, Yes, the same at the transom. You're correct that way they can lay on the transom properly. Thanks for watching.

[@ypaulbrown]

curious about the use of cabinet grade plywood, how good is the glue on that, I have had really bad experience with many brands of this type material delaminating. love your channel though, very informative......best wishes.....PB

[@TheArtofBoatBuilding]

I have not had that experience. Remember this is the mold for the boat, none of it will be in the finished boat.

[@Capnmax]

If the only place your molds are beveled is at the ribbands, I don't see how your planking is going to lay true to the plan. I think it will be pushed off the molds by the difference. Shouldn't each station have a rolling bevel?

[@TheArtofBoatBuilding]

Great question. First I subtracted the thickness of the ribbands from the molds. At each mold station there aren’t any molds that protrude past the ribbands. Even where the bevel is more pronounced near the stem and stern. The oak frames (about 1” sq.)are bend over the ribbands so the planks are alway nearly an inch away from the molds and ribbands. Hope that helps. Thanks for watching!

[@АндрейГоликов-х3щ]

Спасибо за видео. Видно увлеченный человек.

[@shipskepr1]

just awesome,keep it up

[@mydogocoee]

your doing a good job with the video and build, thanks, I am wondering why the transom mold #22? was to high?

[@TheArtofBoatBuilding]

The patterns are design with the cut off in mind. I could have cut it at the angle of the transom. However, frame 22 only goes up to the transom so no need to be angled.

[@scrappybobbarker5224]

It would be nice to have a router that can cut bevels on the mold

[@JenkinsBoatWorks]

Bob, I will be in Mystic at the end of the month, coming from Kansas City. I look forward to meeting you!!

[@clarkkent7999]

Looks like you had to cut approx. 1 inch off of frame #22 to get the transom to fit. How could it be that far off?

[@TheArtofBoatBuilding]

Frame 1 and 22 will be installed from the inside after the planking.

[@gregoryvangundy6170]

Curious as to why you used plywood for ribbands instead of some cheaper species

[@TheArtofBoatBuilding]

I gave my thoughts on the plywood ribbands in S2, Episode 4. The important consideration is that the ribband fairs (bends) very uniformly. The cabinet grade plywood fit my criteria. Cheaper woods would not give the smooth bend that is needed.

[@jhendricks203]

I made a 35' boat while working full time and going to college. Had to work outside ( not in winter ) but I was not as anal about details. Sold the boat after 32 years for what it cost me. Not to spend hours on theory.

[@jimwicks3656]

In your experience or opinion, can the Haven be constructed using strip planking using a double layer of quarter-inch strips instead of the caravel planking? I really enjoy your series.

[@TheArtofBoatBuilding]

Yes it could. What you are describing is cold molding. It would require 3 layers that would be laid on a diagonal. There is a good book describing this in detail. "The New Cold-Molded Boatbuilding" amzn.to/2JkXjXA

[@jimwicks3656]

@@TheArtofBoatBuilding Thanks. I have the book you referred. I was thinking of using traditional strips like 3/4 x 3/16 but I will do some research. I too failed to get a seat in the WoodenBoat School cold molding class a couple of years ago.

I'm not to crazy about Drywall Screws for anything that might require strength. I've broken the heads off a lot of screws when tightening them down. I've was in the Plastering Trade and although Drywall Screws are the cheapest they are not the strongest. I've also seen them rust over time when used in bathroom locations. Love the Video! Thank you for sharing. Because I'm not a boat builder I wonder if I am speaking too soon?

[@TheArtofBoatBuilding]

K Simpson I agree with you comments about drywall screws not being a good long term solution. The mold is a temporary structure. It should never get wet and is not apart of the finished boat. I feel they are a great solution for this application.

[@TheMobileBoatwright]

These are all temporary construction of the hull formers. Nothing here will remain as part of the hull.

[@thomascollin6267]

Not that I have any experience or anything but I would have thought that if you put your moulds on the other side of the station line then the rib bands could be fastened onto the edge of your mould on the station line without having to cut a bevel into the mould.

[@robinhodgkinson]

Screwing those thin ribbands onto the corner of the squared edged of the mold, as apposed to the flat surface (ie the beveled edge ), you would inevitably "rock" the ribband one way or another on that corner. It would only need to be a fraction off when screwed down and the ribband would go up and down in between molds creating hollows and high spots. Those ribbands are easy to bend, and bend out of shape. Cheers.

[@mydogocoee]

the transom knee screws brass , why not bronze?

[@TheArtofBoatBuilding]

Could be bronze. I only needed 3 screws of that size and could nor justify buying an box of them. So, bought 3 brass screws at my local hardware.

[@cornersc]

@@TheArtofBoatBuilding ... curious, if you decided to go back and replace the brass screws?

[@markhgillett]

Scarfing for a boat with wood glue? Should use epoxy

[@TheArtofBoatBuilding]

Hi Mark, the scarfed joints are for the mold only. These ribband ar not apart of the finished boat. Epoxy is expensive and yes will be used to scarf joints in the finished boat parts. As the mold is only temporary and will never see water carpenter glue is the best choice.
