Sheer Plan Lofted Due to Sheer Luck!

Puns are gross. Sorry.

So on Sunday my friend came over (Austin) with my other friend (beer) and the lofting process began....

Well, a lot of talking happened, but the basic lofting of the sheer plan happened which is a successful step in the right direction.

Truly, the sheer plan is the only thing I need to loft the Banks Dory... Curious? here's why:

Lofting enables you to have a life-sized set of plans in order to get angles and measurements 'real-time' as opposed to using a much smaller scale to go off of. If you were to expand those small scaled angles and such to full sized, the margin of error dramatically increases. Boat builders find their most useful information from the lofting operation in the creation of the waterlines. Waterlines are curvy lines in the lines plan that create the hydodynamicness (is that a word? it is now, ha!) of the hull. Anyways, it was really hard for the builders to fabricate these, so the plans were laid out and a long wooden batten would connect all the points to form the curve. Then the builders would 'pick-up' lines from the lofting floor. In short-speak, they made giant templates and used it to cut out the shapes from the wood.

So in a roundabout way, here is why the Banks Dory does not necessarily rely on this process. The Banks Dory does not get its 'waterlines' (not truly waterlines, if you want to know, email me, I don't want to bore everyone to death) from a plan. Her waterlines are dictated by the width of the planking material and the angle of the futtocks. Still lost? What makes the Banks Dory so simple is that her planking doesn't get steamed or twisted but simply bent over the natural curve of the frame. This creates her natural sheer and beautiful lines.

So that's why I don't technically need to loft the profile or half-breadth view. I still will, mainly because it will allow me to calculate the different bevels such as the strakes to the stem, garboard to the bottom, etc.

Now, what is necessary, is the sheer plan. This is a simple drawing, and with my dory, a very functional one. Since there is a set of futtocks at every station, then every station marked in the sheer plan ends up being a template for the futtocks. Pretty neat right? The Banks dory really uses the lines plan to her advantage, simplifying it in some ways, using it to the fullest in others.
Sheer Plan and most boring picture in the world

Enough about the lofting, let me clue you in a little on the logistical side of the house. So far, I have spent $50 on my dory. That was for a sheet of 4'x 8' plywood, 3 2"x4"s, a nice new t-square, and a carpenter's speed triangle. This is but a smidgeon of what I expect her to cost in the long run, especially when I cover her in silk and gold-leaf (kidding, unless there is a generous donor out there.) I will post receipts shortly, so y'all can quietly audit me throughout the process. Note on the quietly.

Spiffy has been begging me for a spot on the blog...
Also, I am having to come to a decision point on where I am to build this lady. I have 3 friends with garage offers, Austin, Seth, and Jocie. I am very thankful to them and their donation and I will gladly accept their offer when needed. There have been some other recent developments and one of my professors suggested that I ask another professor if my school could spare me a space. This would be another excellent option because then my fellow Maritime Studies students can use this as a a type of 'living history' project and write papers and all that jazz. Third option is that I approach a landlord in the Galveston Historic Strand area and ask them if they would be willing to loan me their property for a short time, then that way they could have an attraction to get people to lease the property. Who knows? I'm excited to see where this goes. There are so many options that it makes my head spin, sometimes it becomes really hard to decide what to do and what not to do. But, as my Dad puts it, "...ya I know it's hard when you are young and you have so many choices and you don't know what to do, but it's a hell of a lot harder being my age, having no choices, and still not knowing what to do..."


I will keep everyone informed, this should be an exciting week. I will find out about a space, I check out lumber tomorrow, and hopefully 'move-in' somewhere and finish the lofting. If you like what you see, have questions, or just wanna bug me,

My Dory Model is Ready to Hit the Runway!

Aaaarrrggghhhhh! Sunday is National Talk Like a Pirate Day so I hope y'all are ready to growl and spit your sentences at people all day long. But if you can't talk like a pirate, just use a lot more profanity and you're covered.

Ok so tonight I finished the main phase of my boat model, WOOT!




Ain't she a beauty? No, She's not? How dare you! If you were one of those people who thought "Man, that model is uglier than a bridge troll who has been beaten with a bag of hot nickels..." then you are correct. This model is ugly. Maybe one day when I am 200 years old, retired and am looking for any reason to ignore my wife, I can create a spectacular replica. Instead I am 26, have the attention span of a field mouse, and am in a room filled with way too many shiny objects, so for me to accomplish this I deserve something along the lines of a Nobel Prize (Hey they have been handing them out for nothing the last few decades, why not me?) BUT, that is the point. This model IS ugly. It isn't built for beauty, it's a functional model. 

Functional you might ask? How are these functional? Well, I'm gonna give you a list just on the things it has helped me with:

  1. Visualize my offsets
  2. Made sure they were correct
  3. Checked all around measurements to verify they are correct (Even John Gardner recommends checking well-known boat plans)
  4. Provides a way to make a reasonably close estimate for the length of all your strakes from garboard to sheer (more on that later)
  5. Allows you to ensure frames match the beveling on the rockered bottom to better receive the garboard
  6. Helps with the concept of the bevel at both the stem and transom
  7. Provided a small scale lofting and construction operation so that I can address a lot of logistical issues (I would rather screw up the balsa wood than the white pine or oak)
  8. Kept my sanity (or made it worse, meh)
  9. Etc.
There are many many, many, many more benefits than just this. Models are even greater help with a boat that has a very curvaceous bottom (ooh la la). In fact, shipwrights used to make wooden models 1:8 scale and would pull the waterlines off of it to use in the construction. Making a model was the great grand daddy of CAD (computer aided design) programs. 

Notice on my model, on what should be the frames, I have made them a solid piece all the way across. I did this for structural reasons and so when my cat (soon to be a ship's cat!) bats it off the table, it won't break as easily. It also really helps visualize what the boat will look like. To be honest, mine now has me worried that the 4th station lines are incorrect because there is not a "fair" curve between everything. This is a great example of how it helped me solve a large-scale problem. So, I will go back, check and recheck my numbers, measurements, and all else to find out where the problem is. Better to do it with balsa wood and a hobby knife than white pine and a hand saw...

Ok, no more model talk.

I would like you to check out this guy's website: The Unlikely Boat Builder

This dude has a pretty cool gig going on. He one day just decided to start building boats and he had zero experience. This obviously didn't matter because he has done some really awesome things. This is providing some great info for me and some extra motivation. 

Thanks for stopping in gulls and buoys (yuk yuk, nautical joke hurrah!)

If you like what you see, become a follower, leave a comment, post a link to this site somewhere, tell some friends, whatever you can do to help with the revolution of the Neptune Nation...

The Dory Plan

Ok, so, I've been around boats for quite some time now. I have rigged boats, scrubbed 'em, cleaned 'em, painted, tarred, caulked, steered, unstucked (real word?), etc. etc etc. But there is one important thing I have yet to do to one, and that is

...to build one.

Notice the drama.

To even think about buying a boat is terrifying. I constantly hear that the two best days of a boat owners life is the day he buys it and the day he sells it. So negative, but so true it seems. Boats are a money pit. If you like boating but are landlocked, a great way to experience being a boat owner is to go stand in a cold shower with your raincoat on while you tear up hundred dollar bills. So there you have it, that is how the world has made me feel thus far...

It's not all horrible though. Here on Galveston Island I am surrounded by boats and am a crew member aboard the Elissa, the 1877 sailing barque. Now there's an expensive lady. I don't get to look at the books or anything but I know personally that the dollar amount of varnish I alone have applied to her yards and rails would resemble the GDP for several 3rd world countries. She does bring you back every week though, despite her nagging and high maintenance. That's what a pretty girl is capable of...
They always look good all dressed up


However, I digress, this is about MY boat. That's right, I decided to build my own. Not quite the size of the Elissa, but just as historical. Based on meetings with salty sailors, weather-beaten friends, and well-tattered books, I have chosen a wonderful working-class small boat--The Banks Dory.

The Banks Dory is famous way beyond the space I can spare for its history. It is thought to be derived from the French Bateau, a flat-bottomed, straight-sided river boat from the late 17th century. Yet, since boats were mainly made by the keen eye of a shipwright in those days as opposed to using an offset table or templates, it is very hard to trace its lineage. However, the Banks Dory doesn't need mention of an elaborate past; its fame was gained closer to home in the Grand Banks off of New England. In the late 19th century and the earlier 20th century, large schooners would depart Massachusetts up to the Grand Banks off of Newfoundland. The schooner would be carrying 20 to 30 Banks Dories. There thwarts were removed (seats and stuff) and they were stacked in each other like a bunch of dixie cups. Once there they would anchor and deploy the boats with a pair of fisherman in each. Then, the men would row or sail away from the mother ship and hand-line cod or halibut. The Banks Dory was known for her sturdiness and ability to carry literally tons of cargo. If a sudden squall would come on, it was up to these men to make it back to the ship, and hundreds, if not thousands, of men were lost over the years to events such as that. These dudes were no joke. You wanna hear about a real BAMF? Check out Howard Blackburn. Word of Warning though, standby to feel really inadequate.
Howard Blackburn be his name...
The Fog Warming, Banks Dory in good weather...














Anyways, like I said, I cannot devote nearly enough to explain this boat's greatness.

So on with maneuvers and let us press forward with the battle plan...

The first rule about boat building is that you do not talk about boat building. Just kidding, that's fight club. The first thing you have to do is start reading. Then talking. Then reading and talking. Then ask questions. Then, take all of this abundance of information (sometimes conflicting) and come up with your plan. That's what I did. I have to say though, the majority of my build plan is based off of one book. It's called The Dory Book by John Gardener. This dude is one crafty man. He is incredibly thorough and spares no details. When you first look at some of his line's plans (more on this later) it feels like you are staring at the Matrix. Then when you realize you are the one, you understand it (you mean when I'm ready I can stop bullets? No, when you're ready, you won't have to... ).
I have many leather-bound books...
I can't take credit for finding this book, that goes to one of the saltiest dudes I know. His name is Chester and he is a deckhand for the Seagull which is a tourist boat for the Texas Seaport Museum. He has built a few dories himself and he has stories that go on for days.

The planning is the most important part. I have built and rebuilt this thing in my head numerous times. Right now I am creating a balsa wood model. It's not that pretty, but it's a great way to really go through the building processes. This can help you gauge 'big picture' problems such as "Do I need to build the transom first or the garboard strake?" That was just an example but it all helps, that way when H-hour hits, you are ready.

Right now I'm in the process of securing a good build space, but stay in tune for the next phase which is very important, lofting.

Fair winds, strong rum,
