Laguna 26 mast lowering/raising

I need to get the mast lowered on my Laguna 26. It doesn’t have the normal setup of a plate welded onto the base of the mast with a hinge point on the aft side. Instead, it has a through bolt about an inch up, going through a SS bracket which itself is attached to the cabin top. The mast itself is elliptical shape, about 3” x 4.5”

I don’t see how this can work as a pulpit without damaging the mast. If I start to lower the mast aft, the lower aft end of the mast will have to slide forward as the bolt hinge point rises and then the entire weight of the mast will bear down on this aft corner which will almost surely bend the mainsail lug track. On other similar setups I’ve seen, the aft part of the mast is curved to increase the bearing surface and let it slide forward more easily, but mine just comes to a point. What am I missing? I know the mast is designed to be lowered, but it just seems inevitable that the aft end of the base will be crushed.

To clarify, in the photo we're looking at the mast from forward and starboard of the mast, right?

It would help to see the other side. It looks like the slot is there so that the bolt can slide up as the mast goes down. And I agree that would put a lot of point load at the base of the mast. Does that SS bracket go completely under the foot of the mast, so that it can act as a bearing surface? That would probably be okay. I mean, it's not like the load is tons. Still, it does seem like an odd design.

Yes, you are right about the perspective. I will try to remember to take another picture of the aft end when I go to the boat tomorrow. The stainless steel plate/fitting does completely go under the base of the mast so I’m not worried about the cabin top, just the aft end of the mast when the slot for the mainsail slugs run ... not down that low of course, but still, I don’t want to crush anything.

I doubt it will crush. But you might think about rounding the corner off once you get it down. Even a fraction of an inch of radius would probably help quite a bit.

What is the hole at top of the bracket for? There is another at the bottom.

That looks like the same setup as on my McGregor 22. I doubt that your mast is even twice the weight than mine but even if it were it wouldn't collapse the back edge of the 1/8 inch thick mast as you lower it. The manufacturer would not have designed the tabernacle that way if it was designed only to be set by crane.

LloydB is right! I have a Catalina 22 and I have weighed my mast at 44 lbs. with the stays hanging from it. My sons 28 footer, I can carry the mast across the deck my self.

I have seen that style before as a dealer. Generally the back of the mast at the bottom was cut straight with the backside cut at an angle to allow dropping the mast backwards. Can you take a photo of the backside bottom of your mast

Thanks Dave. Here is a picture of the back of the mast. As you can see, the heel of the mast is not cut at an angle (or curved) like you describe, so it seems all the stress on the channel for the mainsail lugs will almost certainly bend it if I lower the mast aft, unless I can actually lift up on the mast as it’s lowering, but I don’t even think this is possible. Any ideas, suggestions, feedback, etc. most welcome!

Thanks everyone for the feedback. I have calculated that the mast only weighs about 45 pounds, but when lowering it the stress on the mast heel (which is a very small area) will be quite large, which is why I am worried.
