Well, if you're looking for an aluminum boat I'm not a genius, Jon boat part numbers are usually 4 digits, the first two are length in feet and the second two are width in inches.
A good boat for you two might be a 1448. If it is heavy, a simple dolly made from two bicycle wheels would make it easy to move around, if balanced it could take all your gear easy enough for one man to move around. You could even leave the wheels on in the water since speed is not the desired effect.
