My 09 Expo inside on each side of the cuddy has two screwed doors/covers that give access to under the seats. Let me know about the stress cracks. I noticed some near the port rub rail on the bow. I'm not sure when and if anything needs e done.
Stress cracks happen in the gelcoat as it is stiffer than the fiberglass under it. Its really nothing that uncommon in these boats.
Medical Iv bags are strong and may be suitable, even though they are small. Not sure how to get them, I am using 2 of them in my RC Sailboat, given to me by a fellow skipper. The used ones would be fine if it's possible to get them.... bit of a re-cycle effort!14.2 Expo
Any suggestions on alternatives to the hull airbags? Are they as fragile as they look? Anyone have experience with foam or air pillows?
