Ok, it’s my turn to ask a question about my F33!
I took note of two holes drilled into the keelson. One was on the
starboard side outboard of the location of the cutlass bearing. I
suspect this hole is to allow access to a set screw or fastener in
the outer bearing housing. Was that a good guess?
A second hole of about 3/8" was drilled into the bottom of the
keelson about 4" forward of the aft end of the keelson and centered.
This locating is also directly below the cutlass bearing so I have
assumed that it is also an access hole to set the cutlass bearing
from the bottom. Was that also a good guess?
I have seen cutlass bearings with a spiral or heliacal pattern
similar to the groves cut into a rifle barrel. My fear hear is that
by plugging that hole, I could be depriving my bearing of a source of
fresh cooling water as well as the fluid layer that a bearing like
the type I mentioned would need to work properly.
I have seen the new spare cutlass bearing that was aboard when I got
the boat, and it is the usual bearing with the parallel groves so it
would seem logical that the presently employed bearing would be the
same. I seem to remember that the bearing had just been installed
prior to me purchasing the boat.
Has anyone else found a hole drilled in the bottom of the keelson? I
doubt that it maters, but I do have the shallow draft fixed keel
(4.5’).

I have seen holes drilled in the keelson to provide additional water
to help cool the shaft. And yes there could also be a setscrew in
there for the cutless bearing. I would not plug the hole.

My F33 (#68)has 2 set screws for the cutless bearing one on each side… I
don’t see any other holes. I have the same hull (4 1/2 ’ draft). I cleaned
the paint from the holes and saw the Allen set screws.
Cutless bearings will last a very long time if lubed adequately.- I got 2000
hrs on one. They also need water to cool. The slow speed of sailboats
permits water to come up the shaft while underway and lube the rubber.To
check if water flow is present,back off on the packing gland and watch for
water drip.Better too much than too little or none

The keelson: Picture a full keeled boat. Now evenly cut a couple of
feet off the bottom of the keel following the lines of the boat. Now
attach a lead fine keel to where you have just cut way the original
keel. The part of the original keel still remaining (keelson) will
still act as a keel with the addition of the fine keel. I believe
this was done to allow the boat to turn quicker.
Some F33’s have a centerboard that lowers out of the keelson. This
gives that boat a draft (depth) of a little over 3’ (centerboard up)
to about 7’(?)with the board down. You also have the choice of
anywhere in between as this centerboard is designed to keep the boat
balanced no mater how far down you set it. The drawback is that the
housing for the centerboard resides in the middle of the main salon.
Some F33’s like mine have a keel about 8’ long and 2’ deep, this
gives mine a draft of 4.5’ with still better rate of turn than a full
keeled boat.
Some F33’s have a longer(depth)and shorter(lenth)fin keel projecting
down from the keelson. They will turn better than mine, but you pay
a price in draft(about 6’). In most waters this is no big thing, but
if you want to sail say the Caribbean, there will be a lot of very
nice places that you will not be able to go into. As with just about
very thing on boats and airplanes it is all about compromise!
I hope this answered your question on what a keelson is. I am sure
there will be other input on this subject from the board members! I
hope I got it pretty close to right? ? ?

Thanks for the info on the holes! Now it begs the question, does
anyone know how the aft 3’ or so of the F33 keelson is constructed? I
am sure that the cutlass bearing is mounted in solid material, so how
does water get to the froward part of the bearing from the bottom
hole? Is there a hollow area or channel from the bottom of the
keelson to the forward area of the cutlass bearing? I am further
assuming that there is no coring in this area or the boat. ? ? ?

The part of the hull where the bearing setscrews are is properly called the
deadwood. In wooden boat construction,the keelson is inside the hull,lying
atop the keel,and receives the frame ends and the floors.

The UK built 33s ( these are called 35s in the UK) have two 3/8 inch holes about 3 inches ahead of the cutlss bearing on the shaft centre line.

The shaft tube is just that-a glass/resin tube glued into the hull during
construction.Low speed hulls usually have sufficient flow back up the shaft
to wet the bearing

Thanks Jerome for the clarification of terms. Some where back in the
cobwebs of my storehouse of useless knowledge I knew that.
So if the classic trim for the area immediately surrounding the
cutlass bearing is called the “deadwood”, than what is the proper
contemporary name for the rest of the hull above the keel that now
forms part of the effective keel structure? You know, the part that
gives the hull that hour glass shape when viewed from aft.
To me, it is this part of the cat/ketch hull that is the real key to
the genius in the design of this boat and sets it apart from most
others! Simply calling it the “deadwood” or “stem” just does not
seem to do it for me! But then who am I? I have personally not seen
other sailboats with this kind of keel arrangement, so it seems that
there should be a contemporary name for it.

Skip,
I looked it up in ‘How to build a wooden boat’ by David ‘Bud’
Macintosh, a beautiful book that I bought a couple of years ago to
preserve the knowledge about boatbuilding.
The part you mention is simply called the keel. The part below it
they call the ballast keel (which can be a fin keel). On the inside,
its also called keel (inner keel) and on top of that are the
floors. The term keelson is not used by Macintosh. The part around
the cutlass bearing could also be called the rudder post, because
the rudder shaft is above it. Deadwood is also a common name for
this piece of filler wood.
