I looked at that ad. I'm not quite sure how it works.
At first I thought the platform was hinged, at the shore end, but the sea end appears to have cross bracing that would not allow it to be lowered...so does he lift the bows, then winch it up, or does it lower?
I use a similar setup, utilizing SeaDoo lifts. You remove tramp suncover, carry mainsail from garage ,walk onto dock, drop sail on tramp, raise sail, undo securing strap, lower lift & sail away.
There is one disadvantage to his,( & my) type of mast up storage vs leaving it on the beach & having Cat Trax.
If the wind is from behind it becomes impossible to raise the sail. You need shallow water & an anchor or a dock right beside your Cat. I experimented with sailing out into the bay on jib alone, furling jib & dropping a sea anchor, then raising the main. I found it easier to just walk the Cat ahead of the power boat & clip it to the dock with a couple of premade lines, facing the best direction,(there is another 20' of dock ahead of the PB).
In my case 90% of the winds are within 45* of where the Seadoo lift faces, so I can hoist the sail with the Cat still on the lift. My record is 7 minutes from garage to sailing.
