Curious what the cool guys are currently doing to keep water from coming into the interior when going offshore.

Is stepping the stick, tuning the rig, and pouring SparTite into the hole still a valid method?

I seem to remember seeing cuben fiber skirts and full carbon plugs at some point.

a latex boot with hose clamps isn't going to cut it

Spartite will likely still weep a little with no boot, depending on the shape of the partners of the boat and how much wave bashing.

Black vinyl boots > white boots simply based on the sexiness factor

 Spartight is best  .... but is not watertight 

you-need  a neoprene or rubber boot to make the mast watertight ..   then a sunbrella  boot to cover the delicate rubber

rubber, neoprene is not  Uv  resistant and chafes easily 

When  forming the rubber boot , do not stretch the material  ....lay it into position 

rubber fatigues  when stretched 

 

its much easier to make mast boot  when the spar is out of the boat

remember to slide the boot on before stepping 

Use plenty of Vaseline to prevent the spartight from adhering to the mast and partners 

a some boats .... ones in which the mast walls are not parallel to the partner walls ...unstepping the mast,  without destroying the spar-tight ,  is not possible 

If you believe your boat is one of these impossible ones ...mold  a piece of string or SS wire into the spartight when pouring 

In future use this wire , string,  as a cheese cutter to destroy the spartight  plug and pull the spar 

On big boats we use an inflatable inner tube of appropriate  diameter  placed around the spar , then inflated  to help form and support  the spartight pour bulkhead

Spartite can be a great start to a waterproof mast partners. Start by taping off the partners so you can pour 1/2" extra vertical Spartite in. Once cured, taper this extra from mast to edge so water runs off. The Spartite will only leak around the mast& around the partner once it starts moving a bit - use regular caulking around those joints. Cover with mast boot for looks & UV protection

Spartite to do it's job (chocking not waterproofing), then short rubber boot for waterproof, black dyneema stitched boot for chafe/UV protection.

 

Mast butt drain hole plumbed into the bilge or appropriately positioned drain/wet box. Plenty of water will come inside the tube from halyards/deflectors when it's raining.

Spartite then this self-amalgamating waterproof tape. It's pretty great and easy to take on and off. Totally waterproof when done right.

Bring a little extra in case you go offshore and a sheet burns through it or you puncture it with a knife. Spot repairs are as easy as putting it on

Properly made neoprene collars - using outer ring plate and either inner ring or sealing directly to the rig. Halyard/vang penetrations can be accounted for and with neoprene you're able to keep the stretch needed for rig tune and coming on/off the jack without having to remove the collar. You can add a basic UV outer cover to elongate the life the neoprene.

We used something like this found on Amazon. Proxicast Pro-Grade Extra Strong 30mil Weatherproof Self-Fusing Silicone Rubber Sealing Tape. We pumped up the mast jack to max height applied the tape the lowered mast all the way to allow a bellows to be created. After 24 hours applied black sail repair tape to front and sides to be cut resistant. Best boot we’ve ever made. 100% waterproof and flexible in all conditions.

We build the deck to fit tightly agsinst the mast then push in the same materials we use between the hull planking . 
Occasionally we pour the blood of a merchant ship captain around the mast to help the seal stay bloody soft.

We use butyl tape for all kinds of other things. Perhaps you could build it up into a gasket. Throw a boot over it for looks and a rain deflector

This. Run a bead of butyl tape around and cast the spartite around it. Or do the spartite and mush the tape into the joint. Will flex with the rig and should stay wp even when stretched twice the size

+1 especially when I've been bad.  Thigh high.  And bright red lipstick on her sneer
