Blobbing (no, not bobbing) on the Severn River‏

This isn’t in the Urban Dictionary… yet.


(blah-bing) verb

Being launched into the air off the end of a huge inflated rubber bag by people who jumped on the other end… then splashing down in the water.

Gary Oster came across it on the Chesapeake Bay’s Severn River:

A couple of friends of mine, Sean Robinson and Matt Thomas are die hard jet ski enthusiasts who are always trying to figure out ways to make time on the Severn River more fun.

Earlier this summer they organized a spontaneous raft-up of eight boats (24 people) to go rope swinging near the head waters of Luce Creek. Last weekend they organized their first ‘blobbing’ event on Plum Creek.

What exactly is that?

It’s a big — no, enormous — odd-shaped raft. Actually, it reminds me of a Minion laying on his back, floating. It is 13’ x 35’ and nine-feet tall, made of vinyl rubber; the kind of stuff used for making rugged white water rafts.

Blobbing on the Severn River
In Blobbing, people jump off the scaffolding, while a person is laying in the red section ready to be launched

It took 30 minutes to fill it with a high speed air blower that commercial landscapers wear on their backs when blowing grass and leaves. It’s filled with enough air so it can support jumpers and launch swimmers. Jumpers wear high performance skating helmets, because ‘head knocking’ is not unusual.

When the jumpers land on the bull’s eye, the waiting person is launched into the air. This person manages a flip before splashing down. (video is below)


Here is how it works: two guys (the more weight the better) climb up a 15-foot high foot scaffold that has been been bolted and harness-shackled to the dock. Once in position, they count “three-two-one” and jump, aiming to land on the black bulls-eye on the top of the ‘Fat Boy’ raft. The dot locates the optimum spot where the most air projection within the raft could dispel a swimmer to the highest projectile point.

The swimmer is nestled in a cushioned notch that keeps them safe from whiplash on launch. The rest is just physics combined with a little acrobatics.

So when friends ask you to grab a bathing suit and go blob in the water, you now know what you are getting yourself into.


Justin Summers posted this You Tube video in 2013, “Monday Night Blobbing League takes over the Severn river. Couple of bruises and blown-out eardrums, but all-in-all an awesome night. My first time blobbing, and first time editing a video – both turned out pretty well I think.”
