Great Advice. As others have mentioned who would have thought. I have the locking type pin fitted to my bar. Not because I thought the pin was a problem, but more for making it a bit harder for thieves to knock off the whole hitch etc. I have a tow ball lock as well. Didn't think it was much use having a tow ball lock and an easily removed pin on the draw bar. Not totally theft proof if some lowlife wants to steal your boat, but in an attempt to hopefully, make it a bit more difficult for them to do so.
