So on the inflation subject - how many of us wee rubber dingy users carry a pump while on the water? My tub is tiny and I'm having trouble finding a workable solution for pressure loss/repair/refill while on the water. Any of the hand pumps I've seen are either useless or too bulky. I'm currently working on a plan involving a SCUBA mini-cylinder and hose attachment that is very compact/light and delivers about 90L of air at whatever pressure is required. We'll see how that goes...
