A question for Dr Judy or anyone else. On my Mac 26S, the spreaders are raked back and when I raise or lower the mast, I never have to deal with either the lower or upper side stays. Just raise the mast and connect the forestay.
But I have noticed that on other trailerables, some people have to disconnect / connect one set of the side stays in addition to the forestay.
I think (but could be wrong) that if the spreaders are not swept back, that is when when you have to mess with them each time you set the mast up.
Its probably another tradeoff. The swept back speader touches the main when the sail is let way out. But a little more complexity for mast raising and setup if the spreaders are more straight side to side. Is this correct.. or wrong?
Some other observations for trailering.
If you have a furler and keep the foresail wrapped on the furler all the time even when trailering (which saves setup time and I do this), the weight of the furler and sail matters somewhat when raising the mast. A fractional rig will have a lighter furler/ sail simply because it will be shorter length.
Most ramps are about 10 to 12 percent slope. At 10 percent, this means that for each inch higher the boat sits on the trailer, the trailer tires have to go 10 inches further down the ramp. The lower the a boat sits on the trailer, the shorter the ramp you need. The ramp lenght adds up quickly for a boat sitting higher on the trailer. Another example for the 10 percent ramp. If the boat sits up 1.5 feet on the the trailer compared to another boat, the higher boat would need to go say 15 feet farther down the ramp. Something to consider if you are trailering to launch ramps that you dont know much about. And if the boat sits low enough on the trailer, you wont even need a trailer tongue extension. This can also save a bunch of time in the setup process.
FYI, here is my other trailerable from this summer..
