Cigerete lighter cord . I need a more powerfull 12 volt pump to get the full air pressure, that way I won't need the Foot pump to top off...mainly for the floor as it requires more pressure than the tubes and keel.
Deflateing it the Elect pump works well and sucks all the air out.
Takes `10 min's inflating all 4 chambers. another 4-5 min. filling it with foot pump. deflating it takes about 10 min.
With a good 12 volt pump it would take 5 min. inflating it with proper pressure.
I only deflate it if going back from a long trip and won't need it.
It doesn't row well like any inflatable but will get you there in head winds under 5-8mph.
The inflateable floor and Keel makes a big diffrence.
This is just a low cost well built dingy that does what most need.
Light weight at 32 lbs, carry 700 lbs, max. hp 2.5 hp gas and easy storage.
Can you describe how you inflate it on your boat and how long that takes? Or do you inflate when you launch your Mac and always tow?
Also, how well does it row?
