From a practical point of view, it's not obvious to me that it's worth re-emgineering a complicated system like Smith's system on the Telstar28. Re-engineering it looks like a lot of work to me, not to mention that you'll be doing some trial and error fabricating, with the risk of breaking something along the way. But if inventing and fabbing a new system resembling the Smith system sounds like fun to you, go for it. I'm not trying to try to dissuade you. Go for it.
A well executed system leaves little to good luck, chance and requires very little strength. The system that keeps you from damaging the boat or your joints is a well executed one. It doesn't have to be very complicated. The difference between a well executed system and a one that isn't well executed is like night and day.
For masts under about 40 feet, there are several examples of mast raising systems that you can build as a one-off with inexpensive components. These systems, are light weight and really safe, and easily maintained. The combination of a good mast crutch with a clever roller in the stern, a properly balanced mast with the spreaders in the right place, a gin pole with lateral guys with quick connectors can be built in a day or two or three (including attaching the deck hardware properly in a cored deck), I've built three mast raising systems over the years, and seen countless others on other sailboats and online.
The mast on the Telstar28 is only about 34.5 feet long. That's only a foot longer than the mast on my trimaran, and I put can raise and lower the mast by myself, even in a 20 kt side wind. It takes me less than 20 minutes from arrival at the launch to having the mast up and furler pinned, with the gin pole and stern mast crutch stowed back in the SUV. I'm a petite, 5'4" tall 67 year old woman. With two people we do it under 10 minutes.
What takes a long time when I trailer my trimarin is the job of connecting the boom, bending the mainsail slides onto the Tides Track, hoisting the jib on the furler, re-connecting the lazy jacks, running halyards for main, jib, spin and code zero through deck hardware, rigging reefing lines, connecting the outboard and gas, etc. I've got everything leading to the cockpit for single handing, more like a cruiser than a racer, and thats more work to set up than a minimally rigged daysailer. If all the lines stayed on the mast, it would save a ton of time. Having hanked on sails instead of furling would save time too.
Set up takes two people about three hours, from arrival at the ramp or crane to casting off from the dock, working at a comfortable pace without too many interruptions. Break down takes a little longer, because we have to coil all the lines. We have synthetic shrouds, which are much faster than wire shrouds to coil to coil for trailering.
I would never want to trailer and then daysail this boat. We trailer it to distant locations a couple of times a year for vacations and fun regattas.
Our mast raising system works on the water, but we haven't ever needed to do that. If we need to fix something on the mast, one of us goes up in a boatswain's chair. Trimarans are so wide and stable that a trip up the mast at the dock is easy, even if a wake from a passing boat hits us.
