boat is a 2002 37 PC. stays tied up to a floating dock at your local marina. lines have slack, not tight but boat lists towards port side. on the hook for the night so i will add photo tomorrow. any ideas?
 
If your lines are slack, there is only one thing that can cause it - weight. And there are two main things that can cause that - water or gear. Take a look at how your have packed your personal gear. Like every Formula most of your cockpit storage is to the starboard. Is that the side you are listing to? I think I ready the average boat owner of a cruiser style packs about 800-1k lbs onto their boat. If it isn't your gear.....start looking for where the water is.
 
As boatweiser stated, has to be weight of some kind. OP said it's listing to port.

I noticed that mine would list to starboard as my holding tank filled but I also had a lot of tools and other heavy stuff in starboard cockpit storage. I moved that to a more central position and the problem went away.
 
I have a 34PC early vintage. The boat leans to the starboard side. Turns out the two fuel tanks are not balanced and the starboard tank is significantly bigger to accommodate the genny fuel supply. Only I dont use the genny much if at all. The list gets worse as the tanks empty.

So to compensate I use neutral ballast in the form of Sumo Sacs (water ballast) used by wake boarders for ballast .... http://www.slsports.com/ballast-sumo-sacs.html with an integral pump so I can pump in or out water as and when needed although to be honest I just leave 80 litre of water in. This is mounted alongside the port fuel tank. Problem gone and as I said it's neutral ballast. i.e. if I am ever sinking it isn't going to drag me down.
 
BruceK - Curious that your boat list partially because of unbalanced fuel tanks but it gets worse as you burn through fuel? I would think that would get better as your tanks empty?
 
Curious yes. It may be because as it empties the port side tank would be zero on empty but the starboard would still have 80 litres in if given the engines consume exactly the same amount of fuel. Given ratio's of volume the difference when both full is something like 300 / 380 litre but on empty as 1 /80 which as a weight distribution ratio is quite a lot more significant when you then factor in the shape of the hull. Tanks empty the boat is on the deadrise. The boat with full tanks sits on the deadrise AND on the outer Chine Flats. They then may act as, for want of a correct technical term, outriggers on a canoe. But I am guessing. I can only tell you a 80 litre sumo sac on the port fuel tank sorts the problem out.
 
Exact problem im having on a 1993 31pc however on starboard side not port. Its severe, about 4 inches. Something in the realm of 500lbs im guessing.

I know every inch of this boats as i just overhauled, drives engines fuel tanks and did glass work repairs in the bilge.

Im at a complete loss... no gear, now water in foward bilge or aft
 
Hey Biz, what kinda glass work did ya do? Wondering if you might have some of that foam stuff that they use to fill voids that could possibly be water logged?? Did you open up any of these voids during your repairs?
 
It was the entire shelf starboard side in the bilge area. It was rotted and the foam was soaked in water and gas from my leaking tank. I removed the foam completely and drilled drain holes so if water were to get in it would now drain into bilge.

Did not replace floation foam as i found it not necessary
