I have 2 starboard hulls and one port hull in my collection. The surviving starboard hull from our first H16 weighs 85 lbs. The port hull from the new boat weighs 101 lbs. The starboard hull from the new boat weighs 128 lbs!
The heavy hull is the one that had the bondo covered hole in the bottom. I'm thinking there must be trapped water. I'd like to add a port for ventilation so I can dry it out. I see curved inspection covers are no longer available. I've read some discussion on this and the Hobie forums regarding adding inspection covers, but would like to get some more feedback. I'm assuming a 5" cover, between the pylons, with some fiberglass build up to make a flat surface.
I'm thinking I'd do a trial on the 128 lb hull first. See what some heat and airflow would do to the weight.
