SUP board volume and floatation vs. body weight explained

 

We are often asked: "What Stand Up Paddle board volume is best for me?"

The short answer is: "It depends.  For beginners we recommend a volume of about twice your body weight."

Here is a longer explanation of our board volume recommendations:

First of all, you need to know your body weight in kg.  To convert from pounds to kg divide your weight by 2.2.

Using myself as an example:  my weight is 195 lb. divided by 2.2= approx. 88 kg.

The metric system makes it easy to calculate lift created by volume as one kg is equals to the weight of one liter of water by definition (note that salt water is slightly denser so the same board will float slightly better in the ocean than in freshwater).   Interestingly most board dimensions are quoted in feet and inches but volume is always quoted in metric liters for this reason.

Basically: one liter of volume displaces one liter of water and therefore creates one kg of lift, so one liter of board volume will float one kg of weight.

For beginners, we recommend body weight in kg= liters x 2 (approximately) or about 176 liters volume for my weight of 88 kg.  This means that when I stand on the board, it will be pushed about half way under water to displace enough water to float my body weight plus equipment weight.   Please note that more volume will not necessarily make the board more stable.  Side to side stability is a result of the width of the board and the thickness of the rails and to a lesser degree the length of the board.  A thicker board can actually be less stable as the feet are higher off the water, raising the center of gravity.

For racing and touring you can go with a higher volume as thicker, high volume rails can add secondary stability to a narrower hull that has less resistance than a wider board.  In downwinders especially, high volume in the front of the board works well to keep the nose from plowing deep into the trough.

If high performance SUP surfing is your goal, as you improve you can gradually lower the volume of the boards you use since a lower volume board will generally surf better but will also be much harder to balance on and control, making low volume,high performance boards very difficult to learn on.  

Expert SUP surfers can use a board volume as low as their body weight plus board, paddle, clothing and gear weight plus a few liters extra, or about 100 Liters volume for my body weight.  At this volume the board will barely float when not moving.  Some pros even use boards that don't float them when standing still, they need the dynamic lift created from moving through the water to keep them afloat, the board will sink if they stop paddling, with the board volume in liters slightly less than their body weight plus board and equipment weight in kg.  

Once again:  The body weight times two is only a rough guide to recommended volume as the width and volume distribution of the board has a bigger impact on how stable the board will be.  Although we recommend buying a board that is challenging to balance on at first since your balance will quickly improve with practice, don't make the mistake of buying  a board that is too small for your skill level as that can be very frustrating.  The point is to have FUN!

We made this chart as a quick guide to recommended volume for SUP's:

SUP Surfing on Downwind Race boards is FUN!

Surfing on raceboards is a lot of fun and a great skill to practice if you want to get faster on downwind runs, it's all about surfing the bumps.  Surfing these big long boards also allows you to catch and surf waves that others can't, which opens up all kinds of uncrowded spots and smaller waves that are barely breaking that you can catch from way outside,surf and ENJOY.

 These two videos are from our weekly SUP training group, in the first one we go over some tips on how to surf waves on longer raceboards (sorry, the sound is not the best as the microphone was picking up the wind noise).  The second video has action on the water with a voiceover going over some of the tips.  We hope you enjoy the footage.  If you like our videos, please subscribe to the blueplanetsurf youtube channel!

Below is another video of our Stand Up Paddle training group surfing the waves at Maunalua bay on our race boards.  Surfing the waves is tricky and can be dangerous, check out the 3:00 mark where a Outrigger paddler can't straighten out on the wave and takes out Jeff Chang and myself.  Luckily no one got hurt although the ama on the OC1 got cracked in the collision.

Blue Planet Inflatable SUP Kickstarter Campaign has launched!

Blue Planet Inflatable SUP Kickstarter Campaign has launched!

 

We are excited to say that our kickstarter campaign for our newly designed Inflatable SUP line has successfully launched. Within just 24 hours we have made 20% of our goal so far! We spent more than 2 years developing our new inflatable SUP designs and after extensively testing them on a variety of conditions we decided to try and bring them to market at a much more affordable price than other High Quality Inflatable SUP's on the market right now. Our real goal is to get more people on the water, for less.

You can view our kickstarter project here:
