Here's my crazy idea
Lots of people have put a traveler on the step into the cabin and it works just fine, but I don't personally like that placement because I have a HUGE bimini that I want to use while sailing. So therefore, I am looking at making custom brackets and use a Garhauer traveler which I would then attach to the cabin top. I also have a canvas pop-top that the traveler has to fit under hence the custom brackets. I would have to unclip the mainsheet in that instance, but that would be pretty easy. People have worried that you would hit your head on the traveler but they forget that the slider is usually only pushed back a half a foot almost all the time and we don't hit our heads on it.
This would require cutting two 4 inch square holes in the cabin top liner and then putting glued and screwed backing plates in between the liner and roof and then re-attaching the pieces so as not to have big holes in the cabin liner. Then, since no one seems to know the cabin roof fiberglass strength....would a serious jibe tear the roof off....I haven't given up on the idea yet and will wait till Spring to try some prototypes out.
