Barrier Coat and Bouyancy

[Rob Hessenius]

Over the last two weeks I have finished putting on a barrier coat on my Ericson 25. I followed Interlux directions to a tee. Everything turned out just great and I'm sure I will be happy for many years to come. While I was at it this year I raised the waterline up an inch because the boat was fouling on the port side due to what seemed like a constant west wind that heeled the boat under the H2O line.So on Monday afternoon the boat was dropped in the drink. I took her over to the slip and went back to work. Today I went down to the boat and I noticed a full 2" of bottom paint visible. I am just completely baffled by this! I know exactly where the boat sat in the water for the past three years and it was all of an inch plus lower. So I went out for a quicky sail tonight and it seems as if the boat is really "bouncy" (the best word that I could come up with to describe)My question to anyone is if it is possible that the barrier coat has affected the bouyancy? Or is it just possibly in my head since I havent been out on the water in six months? As far as not having the same amount of weight aboard, the only thing that is missing is 3-4 cases of adult beverages and water bottles. Thanks in advance. Rob Hessenius

I would hate to think that one hundred pounds

of cargo would make that much difference. The hull surely didn't dry out that much and the barrier coat didn't increase the hull size by more than the volume of the material you put on. Must be your memory or the wind shifted.

Another possibility

Do the local municipalities in Wisconson use as much rock salt on the roads as Pennsylvania does?If your winter snows were half as bad as ours were this year, there was a hunongous amount of salt droppped on the streets. If the melting, salted snow runs off into tributaries of the lake, you are now sailing in SALT WATER, therefore, the increased boyancy.

Figured it out!

I figured out what was going on. I was in such a hurry to just get the boat in the water. I had not put in the three batteries that are sitting on my porch. 168 lbs under the cabin lowered the ass end right where she always have been... I'm sure this will make her behave as always. I knew, I wasnt going nuts and there would be a simple explanation. Thanks Rob Hessenius

Pound per inch ....

The Ericson 25 is rated at 588 pounds per inch of immersion. Meaning that your boat will sink on its waterline one inch for every 588 pounds of additional loading.
