Drying two hulls. Went all out on one and bought a 6" tubeaxial duct booster fan for one. Then as I was taking a microwave to the trash place, I noticed the perfectly sized fan on the inside and so pulled it apart and have that on the second hull. Covered in black plastic to hopefully absorb some sunlight. Opened the topside drain plugs and I feel a little air being pushed out. Next project is modifying a trailer with some unistrut to carry these.
