If you have water in your launch, whether from a good downpour or just one of those slow, hard-to-find leaks that older launches develop, Dave Deiuliis sent us a pretty cool power tool hack that will save you from messing with hand pumps, bailers, and even sponges: go out and get yourself a Ryobi Telescoping Pole Pump.

This Rowing Hack at work

While this toy isn't cheap, it is portable and runs off one of Ryobi's 18 volt rechargable batteries, so it is perfect for a boat that lives at the end of a dock, a long way from anywhere to plug in an electric pump.

That, after all, is a problem that inspired one of the first Rowing Hacks we ever featured--the Pump-o-matic--and this option doesn't require the big marine battery or hand truck we saw in that Hack.

Deiuliis, the head coach at Assumption University, can attest that the pump moves something like 15 gallons a minute and is, in his words, "so much better than those god awful hand pumps."

At that volume, you can quickly pump out a whole fleet of launches that may have filled up in an overnight rain storm...and having a reliable pump is, of course, essential if you keep your launches in the water during the season.

Deiuliis confessed that he got the idea from the coaches at UMass, which works for us: having a cool trick spotted and copied by another coach is one of the prime criteria for a Rowing Hack, after all.

This is not the only hack idea that we've seen using a product from one of these interchangeable battery ecosystems: one played a starring role in the Erg Race Fan Hack.

You do have to hand it to the toolmaker here, though: this pump seems tailor made for any rowing coach who is a proud member of the "jonboat navy"--and the fact that you can also use the battery for your drill and a bunch of other tools that can help out around the boathouse is a bonus, for sure.

Even we have to admit, the Pump-o-Matic might have met its match
