Pearson Boats - Common Systems > Mast and Spar Issues

mast boot doesnt do the job

(1/3) > >>

The Great Godsea:
I've just never been fully satisfied with the job our guy did at the end of 2013 season. i still see drops of water rolling down the mast in the cabin when its raining. I can't find the spot where the leak is getting through. Have resorted to stuffing plastic and cloth up from the cabin into the space to try and keep it dry. i fear that the water has gotten into the cabin ceiling around the mast. the teak that surrounds the hole is discolored and delaminated. very annoying. anyone have any suggestions? (other than the obvious... re wrap the mast).

although that may be the only solution. it seems like its just not done well and needs to be re-applied.

Alma:
you should be concerned. The cabin top (ceiling is a term used for a different boat part) is plywood with vinyl covering it and will be ruined by rainwater. I used aluminum foil and duct tape on the outside to seal my mast partners when I had a split in my mast boot in the middle of winter. Come spring you will want to strip any mast boot and see what you have between the mast and the Al flange that is mounted to the coachroof. I used Goodyear heavy black garden hose as a grommet between the mast and flange. I was able to stuff two courses with the cut seam fore on one and aft on the other. Now that the mast was centralized in the flange and held tight I used stretch mast tape and it has held up 4 years now. If you accidently kick the tape it will puncture. If not it can last a long time.

selene:
Mt mast is help in place using Spartite - a 2-part rubber-like compound you pour into the partner "well" (with the underside well blocked using putty).  It fills the well, and sets into a stiff, waterproof rubber-like compound, effectively making a one-piece all-around "wedge" which is a perfect fit.  No leaks.

I don't pull the stick that often - apparently it can be reused, coming out as if from a mold; but I can't speak from experience on that.

Bill1188:
I have a large, white, split gasket that fits between mast and aluminum flange. Looks original. I hammer that in until it is all seated, and then wrap everything in duct tape, starting from bottom to top, overlapping every inch. I then have a sunbrella cover that goes over it all. Never had any water enter. Check it every fall.

The Great Godsea:
Great advice. thanks very much to you all
