like the title says.
I got one of the batt. operated intex pump thigys but holy cow it takes for ever.
Do you have any tools onboard for blowing things up like an air pig or comnpreaser 12 volt.
Go to walmart or wherever anyone sells air mattresses. Buy a air mattress inflator. They usually come in both battery operated and 115 Volt AC powered versions. Those pumps are high volume and low pressure.
I use the 115 Volt pump to get the tubes and keel to about 90% inflated and then use the foot pump to top it off. That's the easy part of my boat, the harder part is getting the wood floor and stringers put in.
