Re: Stus-List EPIRB testing and registration

[Mike via CnC-List]

Reminds me of the time we were visiting the Etobicoke Yacht Club.  We were 
getting ready to leave and we kept hearing this beep, beep and couldn’t figure 
out where it was coming from.  Before we could get away some friends stopped by 
and we had a coffee.  I ask them if they could hear that annoying beep.  They 
could but they also could not determine where it was coming from.  While we 
were enjoying our coffee the DO came knocking and asked if we new the coast 
guard was looking for us and apparently everyone on Lake Ontario as well.  We 
didn’t.  He informed us that our EPIRB had gone off .  Upon investigation I 
found that the little pill that dissolves in water had deteriorated.  I 
immediately pulled the battery, and hailed the coast guard tp call off the 
posse.

What’s amazing is that I had never register the EPRIB when I bought Persuasion. 
 The coast guard called the previous owner who gave them my name.

So thank you Marek for bringing this to everyone’s attention.

Conclusion; if you have an EPRIB or any other such devise and are not actively 
sailing SHUT IT OFF.

Thanks
Mike

Stus-List GPS option

[Doug Ellmore via CnC-List]

I saw a post about GPS options just to collect data. Here is another
option:

https://www.byonics.com/products

I have used the bionics GPS with my Kenwood APRS enabled VHF HT for ham
radio applications.

However, for my C 24, I will be using my Garmin GPSMap78sc connected to
my new Raymarine ST1000Plus.  It should allow me to take on other tasks
easily shorthanded sailing, as well as, use course mark in the CHESSS
division races either single or doublehanded.  It would have been nice
during the 2017 Governors Cup sailing doublehanded overnight 20 hrs.  I
spent all but 30 min on the tiller.

Yep, my dad was in the Civil Air Patrol for many years and would be called out 
to look for crashed planes only to find the emitter sitting on a work bench 
behind some guy's house.  Probably not the same EPIRB system, but same

Stus-List Building a hard bimini - part 1

[Joel Aronson via CnC-List]

I started building the hard bimini with the FRP panels from Home Depot
after speaking to the guys at Jamestown Distributors.

Day 1

assembled the bits - MAS epoxy, 2x6s sheet of plywood, foam core, glass
cloth,  and 2 4x8 sheets of FRP panel from Home Depot to use as skins.

Took a 2x6 to the boat and clamped it to the existing frame and marked the
curve. Realized that a 2x6 was not wide enough.
Cut the 2x6, screwed 'extensions' on the end so they were 2x12, clamped it
to the rail. Cut the rest of the curve. Verified that the 2 bows had the
same curve and repeated the process.

Then came the evil FRP. It has a bubble finish on one side that needed to
be sanded. This stuff is hard as a rock and creates a fine white powder
that goes everywhere. You MUST wear a mask! It also consumes sandpaper. I
got frustrated with 80 grit, so tried 60. 80 was marginally better. Did the
sanding on the garage floor. Spent more time on my knees than a cheap
hooker.

Set aside the FRP and screwed the sheet of plywood to the 2x6s to get the
shape.

Realized I was short of foam, so I cut about a 48 x 5 inch piece of 1/4
inch PVC sheet.  MAS sticks to PVC, unlike West.



Day 2 - part 1. Trimmed the excess off to get the size to its proper size
48 by 76.
Cut G10 into squares for the attachment points as recommended by Jamestown
distributors.
Cut holed in the foam core sheets for the G10 to fit in. Measured distance
from the edges.

Did the layup of bottom FRP panel, glass cloth and foam.  Epoxied in the
G10.

Will add more epoxy, cloth and the top FRP panel tomorrow night.

Right now it is fairly flexible.  I'm hoping it stiffens as I go.  The good
news is that if my measurements are slightly off it won't matter.

Stus-List Mast rebuild, stepping, and reference

[Josh Muckley via CnC-List]

Today we finally stepped the mast.  Over the winter we had it completely
stripped, sandblasted, rebuilt and added a few improvements as we went.  A
whisker pole, long range wifi, and new radar being a few of the many
projects.

We took lots of pictures, many of them for our own interest and future

Re: Stus-List Mast step Stringers

[Josh Muckley via CnC-List]

Mine had what looked like medium/high density filler laid under the step as
a leveling agent.  Some of this material was found in/under/around other
areas but nothing in a manner which came close to filling the stringers.
The original screw holes were drilled at a weird angle because the floor
liner wouldn't allow a straight down approach.  Since I cut back the floor
liner to get the step out I now had access for a vertical approach.  I used
west systems six10 to fill all the old holes and finish/dress the step
bed.  I laid the step in place and squared it to the adjacent floor boards,
marked my holes, Removed the step, drilled for the applicable lag bolts
(3/8th IIRC), reset the step and then with a bit of tef-gel between the
washers and the step installed the lad screws.

It's not like there is a significant concern for the mast/step to lift off
the bed.  The screws act as much like an alignment pin as anything.

Part 2

Hi Brian,

The  'stringers' you refer to are the Structural Floors I think.  Those
drawings can be downloaded from the links provided.  They are big, about 3'
by 4' so it is best to download them and view them in a pdf viewer that
will let you zoom way in.

There is a detail on those drawings as follows:

STRUCTURAL FLOORS
1. 2 LAYERS KEVLAR HYBRID
2. 1 LAYER KEVLAR HYBRID ON TOP ONLY
3. 3 LAYERS OF 18oz./1oz. FABMAT

Here is a link to that detail from the Construction Drawing:

Re: Stus-List Mast step Stringers

[Ken Heaton via CnC-List]

" Any thoughts on injecting epoxy? "

It will take a lot of epoxy if the floors are mostly hollow.  And beware of
heat if a large amount of epoxy is curing in an enclosed space.  Perhaps
the slowest possible hardener in the mix?

I am not an expert...

Re: Stus-List Mast step Stringers

[Brian Fry via CnC-List]

Thank you Ken.. Very helpful. I will take another look. I do have an access
hole drilled thru one of the stringers to be able to torque one of the
bolts, If I recall it is not hollow. There are also bilge drain holes from
bay to bay, again they are not hollow.

I agree the drawings show no material inside, but then what would the mast
step plate be screwed to?

My concern is that they are bulging.
I take it yours don't have the bulging issue?

Any thoughts on injecting epoxy?
Thanks again.

Hi Brian,
The 

'stringers' you refer to are the Structural Floors I think.  Those drawings can 
be downloaded from the links provided.  They are big, about 3' by 4' so it is 
best to download them and view them in a pdf viewer that will let you zoom way 
in.
There is a detail on those drawings as follows:
STRUCTURAL FLOORS1. 2 LAYERS KEVLAR HYBRID2. 1 LAYER KEVLAR HYBRID ON TOP 
ONLY3. 3 LAYERS OF 18oz./1oz. FABMAT

a C 37/40.  There is no mention of wood used in any part of this boat's 
construction anywhere (except in the sole, in bulkheads and cabinetry) in any 
documents I have see for these hulls.
I was sure the `stringers` were either completely hollow or there was perhaps 
foam inside, but only to hold their shape while they are tabbbed to the hull on 
initial construction.  One `stringer` just aft of the two that support the mast 
step, has a large hole drilled in the top to access a keel bolt.  It is 
completely hollow.

Here is a link to the construction drawing for that hull:

suupport piece of 1/2" aluminum across the face, bolted into the solid parts of 
the stringer. Any input is welcome.

Part 2

Hi Brian,

The  'stringers' you refer to are the Structural Floors I think.  Those
drawings can be downloaded from the links provided.  They are big, about 3'
by 4' so it is best to download them and view them in a pdf viewer that
will let you zoom way in.

There is a detail on those drawings as follows:

STRUCTURAL FLOORS
1. 2 LAYERS KEVLAR HYBRID
2. 1 LAYER KEVLAR HYBRID ON TOP ONLY
3. 3 LAYERS OF 18oz./1oz. FABMAT

Here is a link to that detail from the Construction Drawing:

Re: Stus-List Mast step stringers

[Ken Heaton via CnC-List]

Hello Brian,

I would be very surprised to find there was any wood inside the 'stringers'
on a C 37/40.  There is no mention of wood used in any part of this
boat's construction anywhere (except in the sole, in bulkheads and
cabinetry) in any documents I have see for these hulls.

I was sure the `stringers` were either completely hollow or there was
perhaps foam inside, but only to hold their shape while they are tabbbed to
the hull on initial construction.  One `stringer` just aft of the two that
support the mast step, has a large hole drilled in the top to access a keel
bolt.  It is completely hollow.


Here is a link to the construction drawing for that hull:
