Waterline for a TC 255?

I'm about to touch up the anti fowling paint on the hull of our TC 255. I was taping off the existing waterline and started to think that the center aft portion of the hull is actually sitting in the water most of the time. The previous waterline has paint just on the two sponsons. Shouldn't there be anti fowling paint in the center of the hull, at least starting at the aft end and going forward for some distance?

Just a thought ...

Hi Peter,
You should have antifouling paint on the wing deck. As you mention when at rest it's sitting in the water. I have paint on the wing deck from the stern to 1/2-2/3 the distance to the bow.

Matt, by "wing deck" do you mean the Armstrong bracket?

Hi Warren,
I have about 12' of paint on the underside of the wing deck from the bracket leading to the bow. I used the discoloration on the wing deck as a gauge for how far I wanted to apply the paint.

How about others? How far do you paint on the wing deck?
 
I remember now that the wing deck is the "top" of the tunnel. Yes, I have bottom paint there as well as on the Armstrong bracket waterline. It is tricky, especially with copper-based paints, because the bracket is aluminum. NP with the new green paints.

Yes, you need bottom paint on the side and top of the tunnel. My Tom Cat is on a lift. But the caracal, with a very similar hull, has about half of the tunnel painted--even though in that boat the tunnel top is not submerged, there is a lot of splash and it stays wet most of the time.

During the boat survey, it was documented that I paint part of the Honda motor mounting parts plus higher up on the Armstrong motor brackets as growth was observed on these parts.


With a full load of fuel and full water tank,
prior to heading out to do the Carolina Loop,
it appears to me that the port side was a wee bit deeper in the water.

Have any of you also noticed this port side tilt?

If so, this port side will then be my reference line for bringing up the bottom paint equal on both sides.


I have been told to use the following bottom paint for our area...
Pettit Protect = Barrier Treatment
Pettit Ultima Pro-60 Slime Resistance.


Come haul out in October, this is the products I had planned to use.


Today I am assuming it can be used on the aluminum parts.

When I went to this vendor to check out this paint I saw that they advertise a high level of copper. When I got my TC painted the first time, back in 2007, I was told that if I used copper paint on the aluminum bracket I would be inviting galvanic corrosion and that I should use a different paint on the bracket -- which I did.

Bill, The 2008 Tom Cat 255 has the water tank on the port side--some of the earlier boats have the water tank on the STB side. With about 30 to 35 gallons of water, that 240 to 280 lbs on that side--with the water heater on the other side--probabaly only 60 lbs. (I have not noted any significant list--and have the water and the heater on the STB side--my refer is on the port side.
