i guess the j 29 has a masthead chute with the same mast and stuff as ours...
would I do it ? I dont really know, masts seem to be on the expensive side....
why not running a regular chute with an ATN slider jobby ( plastic shoe which goes over the furled up jib, you dont need to putz around with the spi boom ) get an ATN sock for it and its easy to do with two people...
A real cruising spi on the masthead would only make sense in my opinion if you rig up some kind of bow sprit as well
