leak
not sure if your 22 is like my 23 but the cockpit drain/hose/through hull arrangement sounds the same and mine did the same thing when i first launched it. i took a friend that had helped me launch it home and went back to the boat to check it and had 6" and rising under the cockpit. the hose from the drain to the through hull had a hole in the bottom where it had worn against the hull and i hadn't noticed it. the through hull is right at waterline. fortunately i had already rigged and wired a rule 1500 and had a long hose ready for just such an emergency. i dropped it in and plugged to a 12v outlet. i stuffed a plastic bag tightly in the through hull, went to the hardware store and got a cork, came back and jammed the cork in the through hull, removed the hose, and went to an auto parts store and got a section of the flexible radiator hose to match and 4 band clamps and replaced it.now, if its the keel bolts and water is just getting into the area around the bolts. my 23 did that too....all last season. it came up about 2" in the aft of the 3 "bilge" areas around the keel bolts. (again, not sure if your 22 is the same). mine stayed that way all summer. i'd drain it and it would refill but come no higher. i was, and still am baffled as to that one. i retorqued and resealed my keel bolts and keel/hull joint last winter and will see how it fairs this year.worst case: if its not the hose from the cockpit drain to the through hull, and if the water keeps rising, get it out and drying while you get the keel bolt torque specs from hunter. (55 ft/lb on my h23 w/ 1/2" keel bolts). remove and reseal the keel bolts and reseal the keel/hull joint, (i used life caulk since it is "supposed" to work under water or on wet although mine was dry it the time. I wanted something a little flexible). do the keel bolts one at a time while the keel is supported by the bunk.good luck! i sympathize. i know how it is to work hard to restore a boat and than find an annoying, potentially fatal leak! ...i learned mine wasn't fatal but still disheartening. from all the posts i've seen i don't think hunter ever built a 23, (or maybe 22 either), that doesn't leak somewhere. most are deck type leaks tho from what i read. i seem to have those too but they're getting better one by one!
