Why are you losing? Your team trains hard but in races you seem to be ploughing through the water. Or dragging the back end of the boat.
Your sweep is constantly making corrections – each time slowing the boat down. The boat is low on one side. All of these symptoms could be related to one issue – an unbalanced dragon boat.
A balanced dragon boat makes for a safer dragon boat. An easier to steer dragon boat. A faster dragon boat.
With a balanced boat the sweep (or steersman) does not have to make so many corrections. Less corrections means less additional drag from their sweep oar. Faster boat.
If your boat is balanced, both left & right and front & back, then it will glide through the water as it was designed to do. Faster boat.
This post will show you how to balance a dragon boat. Firstly the way everyone else does it. Then my (right?) way.
How to balance your boat the conventional way.
Front half weighs the same as the back half. Left weighs the same as right.
Recreational teams partner up paddlers with someone who is more or less the same weight. This will result in an approximation of a left-right balanced boat. But it is not accurate.
Competitive teams balance their boat by making the total of the left weights balance the right. And the total of the front weights balance the back. Often they have spreadsheets that will automatically add up the weights – front, back, left and right. That way coaches can know immediately if one side is heavier than the other.
Sounds logical, right? Balanced weights equals a balanced boat. Right?
I am about to show you something interesting.
Here is a screenshot of a dragon boat balancing spreadsheet using the conventional method. I have deliberately made it (look) back heavy.
If you are happy to use this method, I have provided an online freemium version of the spread sheet here.
If you are curious to learn the new way – read on.
How to balance your boat the Dragon Analytics way
My philosophy when loading a boat is a little different, OK – a lot different – to many others.
Remember back when you were a kid and your dad (or someone heavier than you) would sit close to the fulcrum on a see-saw so that his weight would balance yours? The weight on one side is heavier than on the other but it balances! Hmmm.
I treat my dragon boats as more like a see-saw. I apply the Principle of Moments.
I record the weight of my paddlers AND take note of what bench they sit on. Because it matters.
For example, an 80kg paddler in bench 10 puts more downward pressure on the back of the boat than the same 80kg paddler in bench 6. Yet they are both in the back half.
An 80kg paddler in bench 6 could be balanced by a 65kg paddler in bench 1.
What? The boat is balanced even though the back half weighs MORE than the front half? The answer is “Yes”.
The back half can weigh more than the front half and yet the boat can be balanced.
To stack a balanced dragon boat my way, treat the boat as a see-saw, pivoting around the middle of the boat.
Here is how I would stack a balanced Dragon Boat.
Rank the paddlers by an assortment of metrics including technique, ergo results, timing, etc. The best paddlers are given priority when loading the boat.
Get paddlers’ accurate weights (strangely, the hardest part).
If required, determine the paddlers’ locations in the boat. That is, stroke, or engine room, or near the front, or near the back. I usually determine this from my observations of each paddler and how they interact with other paddlers in the boat. For example: Put those with a tendency to shorten up away from or behind longer reach paddlers.
Then I determine if I want my boat balanced, or slightly front heavy. Front heavy?? Yes, front heavy. There are some teams experimenting with loading front heavy boats. I will be writing a post on this soon.
When all of that data is locked in, I do one of two things.
Load the boat with my best paddlers, on their preferred side, in their area of the boat. Be mindful of what bench they are in so that the “see-saw effect” is accounted for and the boat remains balanced.
Swap paddlers from left to right, forward and back until the boat is balanced. As you can imagine, this can be quite time consuming.
I click “Load the Boat” followed by “Balance the Boat”. Yes, my fine Dragon Boat friends – I have created my own program to do all of this for me. See the screen shot below (names have been removed to protect the not so innocent).
- Although the back half is heavier than the front half, the boat is in fact slightly front heavy!
- Everyone (except 1 paddler) who has a preferred side, is on it.
- The sweep can counteract the fact that the boat is slightly left heavy.
Balanced boats every time, in record time.
Paddlers to get the best return on their efforts, and the sweeps to have a dream run as the boats now track beautifully through the water.
It also allows the option to quickly re-stack the boat on race day if someone pulls out and a reserve with a different weight jumps in.
How much difference does a balanced boat give you in a race? I haven’t tested that yet but it has to be better than an unbalanced boat and even if it is one tenth of a second. How many races have YOU lost by one tenth of a second? Me? Too many!!
This program will be available to you online soon but in the meantime if you would like me to produce a balanced boat for you, download this spreadsheet, fill it in and send it to me.
PS: The Freemium version alluded to earlier in this post includes my balance engine in the spreadsheet.
You will see Fore/Aft Balance and Fore/Aft DIP numbers. The first is the conventional way of matching weights. The second is my way using the Principle of Moments (think see-saw).
The formula is modeled on the Champion Boat. I cannot guarantee perfect accuracy if you have a different boat.
Play with the sample data and see if you can generate a balanced boat even if the weights don’t balance.
