New Moon's trailer winch is a T2005, two-speed with a strap, rated at 2000 lb. It has worked perfectly for 12 years, cranking a boat that's probably 2000 lb heavier than a TomCat. I've replaced the strap with a new one once, but otherwise no problem. It has never bent or showed strain at all.
I may not stress it as much as some do - I generally float the boat onto the trailer bunks with only a foot or so of cranking needed. And I don't launch and retrieve all that often - sometimes only a few times in a summer. I do tow long distances however, 1850 miles in some fairly mountainous country to launch in Prince Rupert, so it gets a fair workout holding the boat onto the trailer. I do have nylon strap tie-downs that help.
