Rowing with the correct length and style of oar makes all the difference in your rowing experience.

A great boat is no fun to row with the wrong oars and a fine set of oars, properly fit to the boat, make rowing almost any craft enjoyable.

Artisan Canoe Paddles by Shaw and Tenney
Monday, February 13, 2017

At Shaw & Tenney we think an artisan paddle should be just that, a work of art, not just a colorful pattern on a piece of wood. We also believe that every paddle we make, whether it’s hanging above your hearth or in the boat house ready for the next adventure, should be of the same exceptional quality and functionality.

Canoe Trip Celebrating the Allagash Wilderness Waterway’s 50th Anniversary
Wednesday, June 29, 2016

In May, our general manager Sam Martinelli and his girlfriend Sarah paddled the entire 92-mile Allagash Wilderness Waterway alone. The annual R&D trip.

In celebration of the 50th Anniversary, Shaw & Tenney created the new Allagash Paddle, part of our Signature paddle line, featuring and engraved map of the entire Waterway hand-drawn by Sam. 

Here is the trip in Sam’s words and his awesome photos.


How to Size Your Oars

To determine the correct length oar for your boat measure the distance between the port and starboard oar sockets. Then apply the Shaw and Tenney oar length formula to determine the oar length that will provide the correct 7:18 leverage ratio. This length will provide an oar where 7/25 the length is inboard of the oarlocks and 18/25 of the oar is outboard of the oarlocks. It is the ideal ratio to row almost all boats. Sized correctly, when rowing your hands will be 1 to 3 inches apart and you will be pulling directly towards your abdomen. If you are popping out of your oarlocks when rowing your oars are far too short. If you prefer an overlapping grip, add 6” to the calculated oar length. If you have more than one rowing station in your boat, measure both. Typically they will require two different length oars which is fine if you’re going to be rowing tandem and need two sets. Otherwise you’ll need to compromise the correct length to work properly in both stations. If you are rowing more than 75% in one station size the oar to that length. As always feel free to call us and were happy to help you select the correct oar length and blade style for your boat.

The Original Shaw & Tenney Oar Length Formula

To help our customers size their oars correctly, we’ve been using the same formula since 1858: Measure the distance between the center of the port and starboard oar sockets, which hold the oar locks on each gunnel. This is called the “span” between the oarlocks. Divide the span by 2, and then add 2 to this number. The result is called the “inboard loom length” of the oar. Multiply the loom length by 25, and then divide that number by 7. The result is the proper oar length in inches. Round up or down to the closest 6” increment.

How to Size Your Paddle

For traditional wooden paddles the ideal length for the Stern paddler is the bridge of your nose or 6 inches less than your height. For the bow paddler the paddle reaching the cleft of your chin or 9 inches less than your height is correct.

For our Racine paddle if you are over 5’6” tall select the 63-1/2” length and the shorter paddle if you are under5’-6”tall.

When paddling solo we typically recommend a bow length paddle. For Canadian style solo most paddlers prefer an even shorter paddle.

For paddling canoes when standing (yes our mother let us do this) a 69 inch or 72 inch paddle is usually about right.
