looking at the boat and trailer, it looks like a MacGregor, I have a Mac 25, you sure its a 21footer? My trailer is almost the same as yours, and looking at the winch that's looks the same too, also the hatch to enter the cabin, though the two windows and the forward hatch do question if I am correct. You might check the MacGregor board they might be able to help.
hi guys. I the mac has different windows and both the mac and the catalina have the hatch differently. this one has the hatch on the angled surface as opposed to the cat and mac which have it on a flat surface. This is a boat i saw for sale for a great price, owner knows nothing about it so i was trying to at least figure out what kind it is.
All boats manufactured or imported on or after November 1, 1972 must bear a HIN (Hull Identification Number). Look for the HIN, read the referenced information Hull ID Numbers - BoatSafe.com, and follow the link to look up the manufacturer. No guess work is required.
