1.) The keel stringer was to beef up for roller trailers. Made from cut ½ PVC . Leave it alone. Good channel for water / Moisture. Keep going & DON'T REMOVE the hull side vents & their inside air channels
2) it looks like that's an old Airmar or the like transducer that was glassed in a mineral oil box? You should be able to cut it out with a jab saw since it not a thru hull install ?
