My comment re my "tin boats" bias was a bit tongue-in-cheek - but I would not use any really light hull in coastal waters, especially because of the wind. So, it's not the hull material as much as the mass. I grew up with wood or 'glass hulls and aluminum was typically found only in very light cartoppers and such. I had such a 12-footer kick out from under me on my 1-acre pond. Nowadays, though, it seems that there are numerous very seaworthy aluminum boats out there. I do not know what these hunters were using - but I like a boat with some inertia to it. Also, hull shape - including freeboard and decking - are all critical characteristics.
In any event, I hope I did not distract from the value of the very informative and well-written article about this truly tragic loss.
All the best,
