Robert,
You raise a very good point. I myself always stress fishing with a partner and yet I was gone with the wind at 6:05 AM hauling across the bay as fast as my feet would take me.
Even with 200 other kayakers on the water at J-Bay, there were hours where I was completely alone.
Thank god that Tim only has a story to tell.
I think it's time for Manufacturers to address hull flex, especially in longer rides. The longer a ride gets the worse the flex. Something has to give way, unfortunately it was a hatch seal. A rubber buffer to absorb flex near the front hatch might be a quick fix for those concerned with this. I don't know if Tim had the Adventurer but at 16' there is going to be quite a bit of hull flex. Maybe the new Tegris material that Heritage is playing with will be the answer and still save on the wallets of anglers.
A couple of points.
1) The boat flex/front hatch leak is still speculation at this time.
2) Tim has the Outback, a 12' long very wide boat specifically designed to carry a heavier paddler.
3) I have the 16' Adventure and Tim and I are roughly the same size. When I got the boat I had problems with taking on major water in rough seas, but never a drop in calm conditions. I found that the gasket on my front hatch had delaminated. Over the winter I reglued the gasket down with marine goop and removed and sealed the other two hatches as well. I took on about a quart of water in 8.5 hrs of very very wet fishing conditions. I did discover last week that the rudder pin in my Hobie is also leaking (it is yet another in a long list of known Hobie leak points). I'm fairly certain that this is the only leak I have left in the boat and will address it ASAP.
