I love designing things and built a half hull model which I spiled and scaled up to full size drawings of the stations. I was pleased to find that there were only a couple of co ordinates that were out, and only by a couple of mm. I find metric is far easier to work with than imperial and bought all metric rulers on a trip to France years ago. This is an interesting topic to cover.
@@Nomadboatbuilding It was a Hereshoff docu that piqued my interest in 1/2 models and it took ages to find any way of spiling off apart from with a complicated vernier device as used in the docu. I am still quite in the dark as to how waterline positions are decided, unless they are just divisions rather like stations, ie equally spaced horizontal lines; the same goes for the buttocks.
@@daleskidmore1685 All of those divisions, waterlines, buttock lines, stations and diagonals are somewhat arbitrary. Obviously even divisions are favoured but not required other than in the case of stations and those only for the purpose of displacement calculations. Getting the load waterline in the right place is important but even that is somewhat of a guess that is sometimes verified only by ballasting to it. There is strategy in the choice of arrangement. The goal is to place them such that they best interact with the hull surface at right angles. For this reason waterlines do the best job of fairing out the topsides while buttocks do the same in the lower sections in the areas like the aft counter. The diagonals are mainly used as a final check because they can have some odd shapes in some orientations but they are also useful to layout potential plank runs so that your planks don't have too great an edge set. Howard Chapelle does a good job of explaining the use of lines in his book "Yacht Designing and Planning". I often throw in extra or partial waterlines or buttocks, even extra stations, to work out details as I am lofting.
@@Nomadboatbuilding Thank you for the explanation. It looks like I was on the right lines when I used a series of horizontals ( water lines ) to measure and scale up from. I may go back to my drawings and put in the buttock lines. I have no idea if the boat would be any good, it was more an investigation into how plans were made from a half model. Thanks for the heads up on the book too.
The primary reason to add buttock lines would be to give you another avenue to fair out and to assist in the accurate scaling up to a full size lofting. Of course the shape of your hull will dictate the effectiveness of any of these lines. Whether it’s a good hull is a whole different subject. It has long been standard practice in boat design to use a proven design as a stepping off point.
I put all my drafting tools in storage many years ago when I left the aircraft design profession for a business career. This really makes me want to dig them out and start drafting again. Thanks!
I've been following your channel for some time and really enjoy it. I came upon it because I was searching for information regarding half modeling. I've recently started making models and find it an enjoyable hobby. I do have a problem finding plans though, and have been trying to learn the basics of lofting. Not as easy as I thought it would be. I will really find this one interesting
Thanks Harry. I'm surprised you're having trouble finding plans but I guess it depends on what kind of plans you're looking for. I assume you saw the first few episodes of my Bouchie Dory series where I walk you through the basics of lofting. It's not a complete nuts and bolts tutorial but should give you some general procedures. The best way to lear how to loft is by doing it. Start with a flat bottomed boat then move onto something round bottomed. Avoid anything extreme in shape. For the purposes of learning you want something kind boring to look at. Greg Rossel's book The Boatbuilders Apprentice has pretty good instructions as does Allan Vaitses' Lofting. I would highly recommend you get a copy of Howard Chapelle's Boatbuilding. It has both excellent lofting instructions and a good variety of plans.
That is a beautiful model behind you at the beginning. My lead duck only sit there. How do you get them to quack? Great video Mark. Thank you and stay well.
Wow great! I’ve been looking for 2.4 plans to build the real deal in wood and haven’t found any- may I ask were you got yours and how I might find a copy?
There's a link in the description. The plans are bare bones. No construction details but it does have some full size body plans, keel and rudder. If you follow this series you'll be able to pick up on how I go about it.
I suppose so but I don't have a set. The calculations are simple enough and there isn't a ton of it to do. I think it's also good practice to work through the math. Even if I'm off it's not a great concern because we won't be pulling anything but rough nominal dimensional information off of this model. This exercise is primarily to explore the planking process.
Loving this series bud, but maybe a warning or heads up for veterans before the machine gunfire out of nowhere? That would mess some of my buddies up real good.
Been watching for 8m18s at a pile of weights, a flexible strip, a strange ruler. No clue whatsoever WTF is happening. Just cut the shadows with reference to the baseline, fox to baseboard, fair the edges, plank it- no?!?!
@@alannewman85 well yes, but I'm working from references that are at different scales so I'm jumping through hoops to get to the part of setting up moulds and planking over them. Some of these videos are just laying groundwork for more interesting activities in a subsequent video. Not everyone is into this stuff but some do like the minutia.
@@alannewman85 well as I look back at this specific video, I agree with you. Upon review I find it murky myself. There are much more interesting episodes ahead I assure you. This one is a bit of a dud.

The solid model method of designing has a much longer history than drawing on paper. Even some of the greats such as Herreshoff preferred it.

The old craftsmen of my youth were right "Let your eye be the judge". Lovely job.
the quality of the craftsmanship and the videos is absolutely amazing
Thank you very much Daniel.

Well I would say get digging!
Really have all your ducks in a row for this one.

Another good reference is "Mystic Seaport Boatshop Lofting Manual" available on Amazon or from the Mystic Seaport.
@@mattevans-koch9353 Thanks Matt. I didn't know about that one.

You just need to squeeze them ducks harder. Thanks Matt.

Nomad Boatbuilding I’ll be following along, but I found no plans at the association’s site. Thank very much for your reply
@@TheSalMaris You probably just need to email the guy - Hasse Malmsten - and ask him.
TheSalMaris you won’t find plans at the association site because it’s not a one-design class. Go to Malmsen Boats and ask Hasse about his plans.
Nomad Boatbuilding I sent him a email already - thank you
Would proportional dividers be of help to you when transferring those points ?

Noted. Thanks.
that was fun. but I'm really sick. I mean, I love math. lol
