You really dont ant to be inflating and deflating an inflatable so dont worry about it. IMHO, once most inflatables are inflated, they stay inflated for the rest of their life of service.
Inflatables are wonderful devices, and make coming and going a breeze. Buy a good one, you'll keep it forever. Get at least a 10.5 foot boat, anything smaller is too small, especially for four adults, even if the load ability it there, it'll feel scary. Get at least a 8HP motor, you will find the ability to zip in and out at 20 MPH both fun and extremely convenient.
My kids always liked the inflatable more than the sailboat...
Certified...in several regards...
