If you are a smaller sculler a spread of cm may be appropriate and if you are a larger sculler, cm. Moving the spread in creates a heavier load and larger arc through the water. Moving the spread out lightens the load, creating a smaller arc in the water.
You need to feel that you are comfortable to open your hands along a horizontal plane well over the gunnels as the blade is prepared for the catch.
This happens in conjunction with other factors but setting the spread is the initial consideration. It is of the utmost importance to make sure that the pins are set an equal distance from the centerline of the boat. Measure across the gunnels of the boat, take half the number of centimeters, and then measure from that point to the pin.
For example, if gunnel to gunnel is 46 centimeters, half of 46 is 23, locate the cm. It should read 57 centimeters if your overall spread is centimeters. Another method to check if the pins are equidistant is to measure from the outside of the opposite track to the base of the pin and check that both sides are the same. You can use this method because the seat tracks should be set centered in the boat.
Once you have finished setting the spread. Measure it again. Do not change your spread casually once you have it set, you can use other adjustments to make smaller gearing changes. Step 2: Determining Inboard Setting the inboard on your oars is another rigging step that relates to overall load.
The inboard is the measurement that is defined as the distance from the end of the handle to the blade-side face of the collar.
The inboard setting is dependent on the overall spread and the amount of overlap of the oar handles or crossover. Thus, if your spread was cm. The inboard measurement serves as a way to fine-tune your load as you may move the collar in small increments to affect the load. Moving the collar towards the handle creates a shorter inboard lever and makes the load heavier. Conversely, moving the collar towards the blade, makes the inboard lever longer and lighter. Measurements between 87 to 89 centimeters allow a great deal of adjustment.
If you need a setting such as 86 centimeters, you also may need to select a shorter overall length of the oar to avoid an excessively heavy load. Step 3: Oar Length The third factor in determining load is the overall length of your oars. Your size, strength, and blade design will affect what length oar you choose to scull with.
A shorter oar lightens the load; a longer oar increases the load due to the longer outboard. Outboard is the measurement from the blade-side face of the collar to the tip of the blade. A standard overall length for a Macon blade is centimeters; hatchet-shaped blades- centimeters. A larger heavyweight man may increase these measurements by centimeters and a lightweight woman sculler may decrease these measurements by centimeters.
Some experimentation is needed in your sculling to set the overall length. Your needs may change as your personal style of sculling develops and you race at higher rates or gain strength. You also may find that you prefer a lighter load if you tend to be quicker and more reactive versus someone who prefers a heavier, power stroke. Remember that spread, inboard, oar length, and personal attributes must all work together.
There is no sense to row with excessively heavy loads to impress others. If anything lean towards lighter loads to protect overstressing the lumbar spine. Step 4: Oarlock Height When you sit in a boat, the first thing that you usually notice is where the handle height is. This can be due both to the size of the boat relative to your weight and to the height set at the oarlock. Rowing with the correct height is a one reason to row the right hull size for your weight.
Accurate oarlock height allows you to clear your blade from the water on the recovery and lets you to apply your body weight properly during the drive. Due to the crossover, in sculling there is a slight height differential between the starboard and port oarlocks of 1- 2 centimeters allowing the sculler to row left over right. This difference in the height setting gives room for the hands to nest together at the crossover and keep the boat level.
The differential setting can be a personal setting, as some scullers may like a little more and some a little less. The important point is that the boat stays on keel at the point of crossover. Standard oarlock height runs between 13 to 18 centimeters and is largely a comfort or stylistic setting.
At the finish, sitting with good posture, and blades buried, your thumbs on the handles should just brush your middle ribs at the level of your sternum. You do not want to feel that your handles are in your lap or up near your neck.
To measure height, use a long level placed across the gunnels. Set one end through the center of the oarlock and hang the other end over the seat. Use a tape measure to establish the distance from the bottom edge of the long level, to the bottom of the oarlock, and the top of the seat.
Every time you measure height make sure to put your level in the same place and measure to the same point on the seat and oarlock to keep the references consistent.
Sliding the oarlock off the pin and changing the number of washers above and below the pin can usually suffice to change height in most boats. Note: When you purchase a boat ask the builder if the height differential is set in the rigger construction or needs to be set at the oarlock; if you row in a boat with a wing rigger check whether the starboard side of the wing is shimmed higher than the port.
Some European clubs row right over left, in which case you need to reverse the standard height differential to raise the port side. Step 5: Sternward Pitch Sternward pitch is the angle of the blade away from perpendicular during the pull through of the stroke. A small amount of pitch, 4 to 6 degrees, is enough to help the blade stay buried at the proper depth through the water.
If a blade has too much pitch, more than 7 degrees, the blade will wash out at the finish; too little pitch, less than 4 degrees, causes the blade too dive deep. Sternward pitch is a fore-and-aft measurement usually taken at the oarlock but it must be kept in mind that it is the angle of the blade that we are concerned with, so knowing the pitch of the pins and the oars has to be taken into final consideration.
Measuring the pitch will begin with checking the pin. Ideally, if the pin is set at 0 degrees it makes it easy to calculate your oarlock pitch. A commercially available pitch meter or a simple level can be used. With your boat set up level in slings, slide the oarlock off taking care to count the washers setting the height. Do short m pieces at firm pressure low rate, come into the dock and get on the erg also on the dock and row m at similar pressure and rate.
Do they feel the same? If no, adjust the erg damper setting and drag factor. How does it affect the set-up? Skip to toolbar Log In Register Drift.
Concept2 is happy to help with your oar-related questions. We can find the right sculls to fit your experience, boat and goals. Many athletes find success with the durable, affordable design of the Bantam , which is a popular choice for a range of athletes including juniors and masters.
If you purchase used oars, inspect them for damage, including soft spots. New grips, new sleeves, and other updates can be installed at home. Boat manufacturers can help you find your best fit into a new shell. Purchasing new allows you to personalize your shell: find the best boat for your skills, abilities and preferences.
You can also check with your local boathouse or rowing team. Do you see a bend in the keel if you pick up the boat from one end? That may indicate the materials have softened over time. A strong boat will have a rigid structure. Also check to make sure the footstretcher and rigger are firmly connected to the boat. Look over the oarlocks, seat wheels and track, and shoes.
Be prepared to spend money on these wearing parts over time. For those looking for an extra challenge, rowing boat plans and kits are available for a build-your-own project. My father built the Oxford Shell II shown in the photo above. Tags: Oars , On-Water Rowing.
