Water check
Alan,Responding to water on top of the water tank lid, sometimes it is very difficult to find leaks.  May I suggest the following:  1. Put 1 gallon of red or pink lemonad     mix into tank and fill with water.     if it is tank, you will see the      color flavored lemonade.  2. Next, look at wing nut to see if      you have a gasket under the washer     and if not replace.  Make sure      drain bail plug is tight by turning     it.  3. Look at the base of compression      post.  Not only do you need to      caulk around the bolt head, you      need to look at the compression      plate that sits on top of the fiber     glass and if you suspect any     openings or crevices between the      plate and fiberglass, take you      finger and work in 5200 but the      area has to be dry.  Also, look at      the base of the compression post to     see if any holes.  There will be      two with one in back and one in      front.  If there are no screws in      them, put # 10 with 24 thread size      and again caulk the threads with      5200.   4.Look at the transom specificall the     hull to deck joint to make sure      there are no splits.  Also,      underneath on bottom of hull you      will find a screw that holds the      base plate of mast carrier pole.      Make sure you dab a little of caulk     over screw head.   5.Check any add ons that are thru      hull below water line.   6.By now you have eliminated any      water coming thru hull below water      line.The quickest way to find out if it is the transom, gasket underneath the washer or compression post in either the 26 or 260 is to add weight.  Get about 6-8 folks and first stand in the rear, then middle and front.  This is what I told Hunter when looking for leaks and guess what they found it.Regarding the Hatchboards, generally, the most leaks occur from  not a long enough piece of wood on the top back portion of the slider and/or lack of caulk between the board and the lexan.You will have to remove the slider hatchand check the piece of wood.  It needs to be the edge of the lexan at both ends and while at it, remove and caulk entire length.  Also check for leaks under the front piece of wood or handle.Hope this helps and I pray this thread will cease and we can get along to other mattersCrazy Dave
