Yikes!

Actually, I went up and poured water in on of the openings in the mast above deck. When I went below water was pouring out of the mast, onto the floor of the head! Previously, I was distracted by the water coming through the partners and assumed the mast was draining to the bilge. NOW, I've got bigger issues! I've addressed them in another thread, and would appreciate your input.

knothead I do the same thing if I have enough material. I tape around the ring and pour the stuff above the lip so that there is no place for water to stand.

When I said that the silicone doesn't have to stick to the spartite, I was specifically talking about using it around the cured plug that is already on the mast and which will be in contact with the ring. It should be a perfect fit and most of the silicone will be squeezed out. If you did that, I bet you have water coming in somewhere else. My first guess would be the sail track. But without seeing it, who knows? It's possible that you used a little too much Vaseline when the spartite was first installed.

L124C Removed the boot to apply more Silicone as I described in a previous post. I was surprised to find the Silicone apparently holding tenaciously to all surfaces, INCLUDING the Spartite. I can't understand where the water is getting in! I've attached a picture in case anyone has ideas.
The old caulk looks terrible, but all areas where I applied new
Silicone were clean. I had extra Spartite when I did the application, so I applied it about a half inch beyond the elevated ring.

I've been doing it that way for years with good success.
You should have a boot over the spartite as well. Mostly to keep the sun off.
That's what I did recently, and it's still leaking. If the Silicone doesn't bond to the Spartite, can't the water slip beneath the Silicone (between the Silicone and Spartite) and into the boat? Maybe I can cover the Spartite with Silicone from ring to mast. I tried that with the Boat Life caulk, to no avail. The mast is pretty stout (Yankee 30) but must flex quite a bit because I could see cracks in the Caulk. The strange thing is that even though I cleaned the mast and didn't use release agent on it when I installed the Spartite, I'm sure water is getting in between the Spartite and the mast. I have a fabric boot to protect the Spartite from UV, but it's certainly not waterproof! BTW, I edited my post you responded to make it clearer.

Bene505 I made a rain catcher inside at the base of the mast that effectives channels all the rain coming down inside the mast into a couple (empty) antifreeze bottles. Before then I was getting just enough water over the summer that I thought I might have a slow leak, and our bolts were getting rusty.

Brad

I'm usually not too concerned about wood rot but rather the corrosion that occurs around mast bases and steps that are constantly wet with salt water. I know that salt water is much better for wood.
Again, make sure you have clear limber holes, keep the step from sitting in a puddle of water and provide a little ventilation. It'll be fine.

Fresh water GOOD, Salt water BAD...Ain't necessarily so!

I understand the distinction between the interior and exterior of the the mast. However, given the topic of this thread, I think we should avoid the impression that fresh water leaking at the partners (not "inside" the mast) is OK . Here is a a thread I created which is slightly off topic, though certainly related. It's the main reason the leak at the partners bothers me.

I rank Spartite as one of the all-time great products.
I just pulled out the Spartite instructions and stand corrected. They only recommended coating the mast with release agent if the boat has hydraulic jacks at the mast step, a bendy spar, or if movement is desired without bonding the mast. They also state that the seal will be better if the spartite is bonded to the mast (of course). Based on my search of this forum, it seems that some boats seal tighter than others with Spartite. Initially I used the caulk Spartite recommends ("Life Seal by Boat Life") to seal the perimeter. It seemed to work briefly, but after a couple of windy outings, I noticed water penetrating. The funny thing is, a couple of weeks ago, I was using some Silicone for another project. I noticed the Silicone insructions said "unlike other caulks, Silicone retains it's elasticity". I thought..."Hmmmm, I wonder if that might solve the Spartite problem?". In the back of my mind, I thought there must have been a reason I didn't use it when I installed the Spartite, but thought "Well, that didn't work, so what do I have to loose?". I cleaned off the Life Seal and installed Silicone. It seemed to keep the rain water out for a couple of weeks (without sailing), but is now leaking like a sieve! In reviewing the Spartite instructions, they state "Do not use Silicone, it will not bond to Spartite". ! Anyway, the difference in results with Spartite between boats/owners is interesting. Glad it's working for some! It certainly wasn't worth the effort for me. I'll probably re caulk with Life Seal and reinstall the boot I was trying to eliminate!

knothead As far as sealing the inside of the spar, Selden does a similar thing to the spartite. They make a dam and pour something inside the mast above the partners and it prevents water from making it below. It works well for that purpose, but what a pain if you need to run something else up the spar. I can't remember what it was but we once needed to install one more wire in the spar of a new boat that wouldn't fit in the conduit. Some people add a lot of stuff. I made a 12' hole saw out of a piece of aluminum pipe and was able to get through it but there was no way to really seal it again.
In my opinion, water coming down the inside of a mast shouldn't be a problem. It's fresh water, so as long as there are clean, adequate sized limber holes, the step isn't sitting in a puddle of bilge water and there is a little ventilation, not much is going to happen to it.
I usually apply a coat of grease to the spar where it contacts the step or shoe to help ward off corrosion.

Therefore, when the mast is unstepped, the Spartite will come out with it, and will be in the proper position when the mast is re-stepped. I complied and sealed both perimeters as instructed, and have never achieved anything close to a water tight seal. Given the expense, effort (my partners made for a ticky application of Spartite) and the fact that a water tight seal was my main objective, I've been disapointed.

The next time you step the mast, apply a layer of cheap clear (I hope Mainesail isn't listening) silicone to the surfaces. It'll break easy enough the next time you pull the stick and should make the seal water tight.
