Bearing in mind I know nothing about boats, the 'takes on water' bit in the advert worries me a bit. Could this be a rotten hull??
It also says there is a hand operated pump, so nothing to worry about as long as you have a strong arm ????
But seriously, take a screwdriver and tap the handle all over the hull and listen for any dull thudding which could indicate rot. Check the join at the centreboard case and where the bungs come through the transom. Pull up the floor boards and check all the frames.
My hartley used to take on water through the centreboard pivot bolt which is quite common.
The seller isn't specific, he might just mean it has a low freeboard and water splashes over the side
