The gentleman below this post shouldnt feel alone. Hackers, Chris Crafts and Hutchinsons also have met the river bottom. Many many other boats too. Sunken islands are rediscovered there every year by the transient boaters, yachtsmen and commercial skippers that stray from the river's navigation channels. Many a sailing ship, merchant and military, went down over the years as well and many wrecks are still uncharted or not even found yet.
Many mysteries remain in that incredibly beautiful part of the world.
Its a serious boater's paradise for sure. Luckily all aboard were fine but we lost everything aboard including our personel items and a 2 year old Honda outboard that I just picked up from a tuneup. The cold water in the darkness after a collision like that is enough to retire from this. It could of been worse and we are greatful but we decided to let her rest there or leave it for someone else to fiddle with. A new engine was installed in '94 and the boat was yard maintained since new and always in fresh water.
