We had one, carried on stern davit, and the bottom corroded through, apparently due to diesel gases combined with salt water. 5052 alloy aluminum is not the best salt water material.

Thanks guys for the info . I called the mfg, but haven't heard back . They used to be in your neck of the woods but they are just 20 minutes from where I live now .
Owned a 16 footer, was a great boat but was a trailer boat and not a tender. I sold it about 10 years ago to a small fish processor. He uses it daily during the season to run his waste to deep water.
