What does the designed do to prevent water from intruding? Are there seals

I own a Tartan 27 Yawl which has a CB. At first I was concerned about the extra maintenance item but it's really not a big deal considering the advantages
Cruising Buzzards Bay is awesome with the CB as I am not as worried when anchoring
as I only draw a little over 3 feet...What this means is I have been able to anchor
in filled harbors where other boats simply can't come close to...So I had grabbed the unique spots when the filled harbors on traditional deeper keeled boats could not...Also, when going through tight channels it allows me more room...General cruising wasn't as much a concern either opposed to my buddy's 28 footer who draws 6 feet
Performance wise, it allows me to balance the boat in a way that it pretty much sailed itself when the sails
are set right and the wind
and waves cooperate...I played around with its position many times depending on conditions so the more experience you have, the more you will learn about which is best for the conditions...When close hauled, you put it down all the way so that it sailed closer to the wind
Maintenance wise, I lower it and paint
it just like the bottom...Last year, I did not paint
the trunk as I read and old wooden boat book where they did not paint the trunk, just the centerboard...The thinking was that it was not needed because the board being in it's trunk would make the trunk area caustic enough that marine
growth was not possible...It seemed to work fine follow this theory for me last year
I did end up taking the board out last year because I had hit a rock with the board down (stupid me!) and it opened...I glassed, faired, and painted it and then put a thicker stainless pin on which is meant to rotate on so that the rocking side the side of would stop...It worked wonders as we no longer heard the trunk banging against the trunk walls while anchored or sailing...It could have been worse with a regular keel as this reef I went over would probably have destroyed my keel but since it was a CB, it just banged it and it retracted back when going over it...
It's housing/home is considered a trunk and does have a spot which is open to the bilge
but on the Tartan, this is glassed in to the trunk with each side having a brass cap which cab be unscrewed in order to reach the pin that it rotates on...
As for how it lowers and how you raise it, it is done from the cockpit
through a regular sheet which attaches to a block...inside the wall would be a wheel
which this sheet goes around so it kind of works like a pulley...It's very simple stuff that anyone can fix if something goes wrong
I am planning on replacing the stainless wire the board is attached to (which attaches to the pulley) with something more like a synthetic...Reason is I am afraid the wheel
will fray the stainless wire when winding and unwinding the the board...I'm thinking of using Dyneema
as there seems to be less a chance of the pulley wheel fraying something pliable like Dyneema
What Tartan are you looking at? I am a big fan of them
Many great boats were made in CB...Some of my favorite "next" boats have a CB:
Bristol 35.5 (some do)
