16 Ways to Get Better at the Physics of Rowing

(This is scary stuff. Buckle your seat belt.)

Physics: the science of matter and motion.

(Told you it was going to be scary.)

If you were pressed hard you could divide rowing into two distinct spheres. The first would be the art of rowing. This “art sphere” deals with human factors such as motivation, team work, leadership, etc.—those human issues where there may not be a distinct right or wrong answer, but an answer nonetheless.

The second sphere would be the science part, specifically physics. Yes Physics. The same word that has freaked out an unlimited number of students and drove more of them to be English majors faster than the thought of Jane Austin could drive them away.

Over the past two weeks I’ve received several inquires about the physics of rowing, so I thought instead of addressing each separately I would post this. I spent years studying the physics of the ocean. When I started I remember thinking, “Wow, this will be cool!” And for the most part it was. Really cool. But there were so many dry, boring, difficult parts that physics about drove me nuts.

The main reason was that the way it was taught and explained. It was removed so much from reality and kept in the theoretical world that it was hard to really like it and see how it applied to more than just a few experiments and line drawings.

But since then a day has not gone by that I haven’t used some of my physics background in rowing. And if you row, or coach, or just work on the equipment, it is the same for you, whether you know it or not.

Physics plays a huge roll in rowing.

How To Measure the Span in a Rowing Shell

Published by under Leverage, Rigging Concepts

Scullers . . . this one is for you!

In sculling span is a very critical measurement. It tells the distance between the port and starboard pins. This is an important dimension of determining the leverage of the boat (how heavy or light it will feel).

Many scullers just stop once they get their span measurement, but there is a need to go one step further. The distance of the pin from the centerline of the boat needs to be equal on both sides.

In other words:

Span is really not very helpful without also knowing the spread.

This short video will explain how to do both. It was requested by a reader (whose name I cannot find . . . sorry). Thanks greatly!

Have a different method, or got a question or comment? You can leave it below.

Row Slow . . . and get more out of life!

Keeping Your Rowing Fast When The Economy Slows

Published by under Rigging Concepts, Think Different

dollar sign
Downturn . . . Buyouts . . . Recession. Turn on the news and daily we are told in some manner or form that money is going to be tight—really tight. And whether you row by yourself in a single or on a team with 50 other people, rowing is the type of sport where money makes a difference.

I’ve written a two-part post about the mindset you might want to have as our economy struggles (Part 1 & Part 2). A few followup emails asked about specifics things that could be done—steps taken to keep a rower fast as the economy slows. Following are a few suggestions, and links to posts, you can do (and read) that just might help you keep things fast in a tough money time.

Suggestion #1: Know what you have

Knowing what you have is so much more important than knowing what you want. Have and want . . . two critical words when money is tight. Why? Because knowing what you have can make a big difference on getting what you want.

Last month I needed two coxbox microphones to replace two that had just broken at practice. We didn’t have any so I bought them from NK. I needed them in a hurry so I paid for the zip shipping.  Just last week I found exactly what I needed—two microphones—in a drawer in the boathouse. I spent money for shipping and my time to get something I needed, when I already had them.

Measuring the Work-Through in a Rowing Shell (Basic Rigging Video)

Published by under Rigging Concepts, Work through

Work-through is a very interesting measurement, for two reasons. First, it helps determine the position of a rower’s hips in respect to the oarlock pin. Second, there are numerous ways to measure it.

The following video shows my way to measure the work-through of a rigger.

Hope you find it helpful.

Measuring Rigger Height in a Rowing Shell (Basic Rigging Video)

Published by under Rigging Concepts, rigger height

The height of a shell’s rigger is important for two basic reasons: efficiency and comfort. When the height is right both of these components are maximized. When the height is off the rower will either be less efficient or uncomfortable, or both.

I recently wrote on how to do a super simple quick rigger-height check while on the water. The following video is about measuring the height while the boat is in slings (although it can be measured while the boat is seats down if you are adventurous).

The steps to measuring are simple, and so are the needed tools. You can go more advanced with tools, such as with the Active Tools rigging stick (which I like) but a basic tape measure and straight edge is really all you need.

Hope this video helps, and if you have questions or comments please leave them below.

Super-Simple Height Check for Your Shell’s Rigger

Published by under Oars, Rigging Concepts

Recently Rob submitted this question:

Hi Mike,

I have a question regarding rigger heights. We are a men’s masters crew and as you would expect there is a wide variance in body shapes and sizes.

How would you set up the boat? Would you work on an average height or set up each individual rower?

For example our stoke is 6 ft 3 inches but the average height would be 5ft 10 inches. From my perspective I am 5 ft 9 with short legs and long body, so I sit quite high in the boat and find drawing up to my sternum at the finish difficult at times. Any assistance would be greatly appreciated.

Rob, good question. Here is what I suggest:

I would certainly have rigger heights set per the person, when you get to the stage of knowing who rows where. Easiest (and best) way is to do a height check when you first launch. Following are those steps:

  • Have bow 4 set boat
  • Stern 4 go to finish position, blades square in water
  • Make sure that the blades are buried as you want the finish to be set
  • The outside arm should be parallel to the surface of the water. If the wrist is above the elbow, probably too high. If the wrist below elbow, probably too low.
  • Then have stern 4 set, and check the bow 4
  • Adjust riggers accordingly, and take a test row.

Yes this sounds super simple, and for the most part it is.

Measuring your riggers in the boat bay works well but it doesn’t account for the crew’s average weight not being the same as the average weight that the builder made the boat to carry. This simple Height Check accounts for that and has proven itself over the year.

Good luck, and Row Slow!

Measuring The Stern Pitch Of A Rowing Shell’s Rigger (Basic Rigging Video)

Published by under Pitch, Rigging Concepts, Tools

For the next installment of our Basic Rigging Videos we present how to measure the stern pitch.

Stern pitch is basically the angle the oarlock pin has towards the stern of the boat. Since most oarlocks today come with pitch in them we measure the stern pitch with the oarlock on the oarlock pin. This is done, measured, with a pitch meter.

There are many pitch meters available, and I plan on a review of some of those in a later post, but for this video I use a meter made by Bill Leavitt. Bill has made some very handy rigging tools and is a wonderful coach (since retired). If you have a chance to try one of his pitch meters, I suggest you take advantage of it. They are simple, and work well.

There are a few steps you should take before measuring to help you get the best readings:

  1. Put the boat in a safe spot, in good slings, so not to worry about it falling over
  2. Make sure the oarlock is clean and not worn
  3. Take the measurements in a place where you have enough light, and space, to read the meter and move at your own pace.

I’ve measured the pitch in a wide variety of places, and even with the boat upside down. You can do that (although you probably don’t want to make a habit of it) and get a good reading but it takes a steady hand and experience. If you are just starting out find a quiet place that is has good light, and take your time. Double check your work.

You do not need to worry about the boat being level from bow to stern, it can be at an angle. But for accurate readings the boat should be level from side to side.

The video explains the basics.

Measuring The Spread In A Rowing Shell (Basic Rigging Video)

Published by under Leverage, Rigging Concepts, Uncategorized

If I had to pick the one rigging number I feel is most important to a rower—in terms of the equipment—I would pick the spread.

To me the spread is the foundation that the house is built upon. If it is not correct then regardless of how well the house is built from that point up soon there will be problems, most likely major ones.

For you scullers out there who are getting ready to tune out this post I will say, “Read on!” Scullers need to know how to measure spread also. Although you use span (the distance from one pin to another) the only way to tell if the pins are equal distance from the centerline of the boat, and not skewed to one side or another, is to use spread.

The nice thing about spread is that it is also one of the easiest measurements to find. With a regular tape measure you can take your measurement in a matter of seconds, regardless of the position of the boat (guts-up or guts-down).

The following video will give you the lowdown, and here is a quick step-by-step procedure:

  1. measure the width of the shell at the rigger position where you desire to measure the spread
  2. divide that number by 2 (one reason the Metric systems rocks!)
  3. take that number and place the tape on the gunwale at that mark on the tape
  4. extend the tape out to the pin
  5. find your spread mark where the pin intersects the tape

Give the short video a watch for some tips and to see it in action.

Can You Help Make This Rowing Resource Better?

Published by under Rigging Concepts, Think Different

I usually get several questions about rowing terms, what means what, and the like. So I thought that I would put up a rowing terminology page. It has 87 terms so far.

I wanted to post it first to give anyone a chance to add words (especially non-US terms), change definitions, or suggest improvements. If you have any please leave a comment. I hope to have the page up in a week.

  1. Adjustment: moving the dimensions on rowing equipment to best suit the needs of the rower(s)
  2. Aft: towards the stern or the back of a boat
  3. Back stop: small blocks on the fore part of the slide that prevent seat as-sembly from rolling off the slide
  4. Beam: width at the widest part of a boat, usually measured from inside of gunwales Continue Reading »

7 Questions A Rowing Coach Should Ask Before Firing Up That Outboard Motor

Published by under Rigging Concepts, Safety, Think Different

Several years ago I wrote this article for row2k.com (one of my favorite rowing sites). It has become dated so I’ve added some text and links, since the time of season is right to think about this.

An email arrived from a reader who was all excited about rigging. (Yes, it does happen - some people do get excited about rigging.) He wanted to know what to bring in his launch in case he had to do some quick rigging on the water.
IMG_0771
Unfortunately, I was in a hurry so I quickly responded, “Ask a few simple questions before you start your launch, then you’ll know what to bring.” I sent the message and went about my business.

Not satisfied, he wrote back, “Questions, what questions??”

Still in a hurry I shot back “Questions . . . ?” I told him, “You know . . . about stuff. Important stuff.” As soon as I hit the send button I knew that was a lame response.

He called me on it. Two minutes later he sent another request for details.

Trying to do three things at once - and realizing that I was doing none of them well - I took a break and gave the writer the time he deserved. “Okay, seven questions. You need to ask seven specific questions before you pull on the cord to start your motor. Without those questions no rigging is going to happen on the water, and you’re going to get into trouble somewhere along the line. And here are the questions:

  • Question #1: Got gas?
  • Question #2: Wearing your PFD?
  • Question #3: Paddle handy?
  • Question #4: What’s the weather?
  • Question #5: Who knows where you are going and when you will be back?
  • Question #6: Communication device (cell phone, radio) nearby?
  • Question #7: Got spare parts?
