I am looking for a JIB & Main Sail for MG 21. Does anyone has a set or either one for sale? If not what are the dimensions of these sails? I can't find any spec. on line. Thank you very much, my email address is(jabrahimzadeh@gmail.com) Jay

for information on sail sizes. I have a V21 with the original jib and main sail, but my genoa doesn't really fit the boat. I think you'll also need to determine whether you have a mast head rig or a cat rig. Mine is cat rigged and seems to have a smaller 100% jib than the mast head rigged boats.

Mast-head versus Cat rig
I talked to Bill at the MacGregor factory about two weeks ago and he convinced me that the Venture 21 and MacGregor 21 models came with either a mast-head or cat rigged mast.
The cat rigged set-up consists of a fore stay and two shrouds but no spreaders. This system flies a smaller jib as a head sail and no genoa. There is also no back stay. All three are stainless steel cable and connect about 4-6 feet from the top of the mast. I initially called this a fractional rig, but he corrected me, so I'm not entirely sure why (It does look similar to the rigging we used on Hobie cats back in the '70s).
The mast-head rigging consists of a fore stay, a back stay as well as both upper and lower shrouds. The upper shrouds are use spreaders and run to the top of the mast along with the fore stay and back stay. The back stay is not split, but runs to the starboard side of the transom to clear the tiller. This system allowed the use of much larger head sails including a bigger jib, a 150 genoa and a spinnaker.
Since I fly a 150 genoa, he recommended that I change my rigging to the mast head configuration. It also provides additional visibility as the genoa almost rides on the foredeck when sailing ... with the forestay moved to the top of the mast I can add a foot or two of clearance to the fore deck.
In any case, I've fixed the link above and from the sizes, I'm guessing that the V21 pre-1980 sail sizes match mine and were designed for the cat rigged boats. The V21 post-1980 sail sizes are bigger and are probably for the mast-head rigging.
