Crazy idea that might just work
boat water leveler
Some used dye to marked it hmmmmm I dont like that idea
since you have to ballast the boat to get it level correctly
if your ballast is to heavy
Then you have marked the boat to high
Some use tape idont like it either
That to much hassle for me
Tape it remove it re tape it nope dont like it
So I came up with the idea
Lay down the boat on a leve surface like your table
just make sure the boat is level
Get a block
Drill it right through
insert a pencil
Aligned that pencil to your boat water level
And slide it around your boat
Marking it all around
dont mind my drawing
Im no Picasso
