Aftermarket parts
Though my boat is an E23, I believe the mast section is the same (6.5 X 3.25) as that of the 25. Mine did not have the optional factory gear for dropping the mast, but I was able to make some up that works real well on it. Dwyer sells a hinge that is just about right for this section: part # 2150; it cost $55.45 a couple of years ago. I came by a boom bridle that was originally for a Mk 1 boat, so the dimensions were off some, but have come to realize that the main issue with it is to hold the boom centered during the first 45 degrees or so of raising - after that the upper shrouds and spreaders take over that task and keep everything from falling off to the side. The hinge raises the mast about an inch, so you need that much extra in the shrouds and stays. I added toggles to them, so that gave the required extra length as well as lessening the possibility of kinking. I also have photos and a sketch if anyone wants to see them. Two people can do it with relative ease, though it's good to have more the first time.
