24' aluminum mast on motorsailor

This 24' deck stepped aluminum mast has an irregularity or damage pictured below. I think is was there at purchase some 18 months ago. Are there repair options? Please advise. Thanks in advance.

Looks like it needs a new coat of paint.

Hard to tell from the photo, but appears that someone tried to fill some major corrosion/possibly holes.
You would need to do a closer inspection to get a better feel of the situation to see if the corrosion was more than cosmetic.

If they are holes or deep corrosion near the base, could always lift out the mast and sleeve the inside of the mast to strengthen it.

Re: 24' aluminum mast on motorsailor

I've looked as cclosely as I can, and I think that I see some corrosion of the aluminum at the bottom of the area with chipped paint. I suggest that you sand (by hand) back to good metal, prime and paint. Only if the corrosion turns out to be widespread or right through the mast might this become a serious problem.

more photos. more digging. Looks like there were fittings here? and there are holes on both side of the mast, but it looks like the fittings were ripped out or I don't know. Also, is there normally wood inside an aluminum mast?

Is that mast original to the boat? With the new pictures, it looks suspiciously like you are looking at the hinge pin channel for a mast that can be lowered. That could also explain the wooden reinforcement.

Hmmmm...I will contact the seller. The original owner built it and is deceased. I know it was launched without a mast but perhaps it was just to facilitate the 30 mile trailered tow to the boat ramp.

Re: 24' aluminum mast on motorsailor

The new additional photos are helpful, but w/o the original builders input, it would be just a guess on what his original idea for the mast base.

My best guess is the guy was fairly good w/wood and made a mast base w/an insert of wood. He probably grabbed a second hand rig from a yard and fitted on this boat. Since it doesn't appear to have any fastener holes in the inner wood (hard to tell from the pics), the corrosion holes that you uncovered were probably from some old hardware that was removed/not used on this boat.

From the approx. position of the wiring insert in the mast, the wood insert goes up ~1'.

Does the inner mast base wood seem dry? What does the standing rigging look like for this mast?
