Re: Stus-List Cockpit scupper drains - stories version

[Greg Swetka via CnC-List]

I also have a 35mkII and I know for a fact that there were never 4 thru hulls. 
Mine aft ones were always teed to the forward ones. The aft ones always held 
water as the hoses went straight down and looped back up over the partial 
bulkheads before connecting to the forward ones. I recently improved that 
condition by attaching 90 degree elbows directly to the drain and then routing 
to the forward tee.

Many races also have specific requirements around the size of scuppers vs. 
cockpit volume.

Be interesting to plug them, fill the cockpit with a few inches of water and 
see how fast they drain.  I'm guessing marine architects have guidelines for 
how big the flow area for scuppers has to be for a certain area of cockpit.  
ABYC may even have such a guide.

My point is if there were originally 4 thru hulls and now only 
2.

Same here.  The aft cockpit valves were removed and the aft scuppers were T'ed 
to the forward valves.  When I was getting the bottom of the boat ready for 
paint I could make out the where they had been.  It was most likely done at the 
factory as Fireball was campaigned by C in the 1975 SORC series.

And the 35  MK1 has a very low companionway/bridge deck but lots of volume
to fill with water below decks. I could be about knee deep in water in the
MKIi cockpit not the same in the MKI.

On my C 35 MKII the after cockpit drain seacocks have been removed. The
hoses for the aft cockpit drains cross over and exit into the forward
cockpit drain seacocks.

Re: Stus-List Cockpit scupper drains - stories version

[Lee Youngblood via CnC-List]

Hi Don,

I have a 1974 C 35-II with the same drain plan.  I’ve sailed in >34kts in 
Puget Sound (I didn’t look after that) and some puffs were around 50 - reported 
by other cruising boats, returning from the same raft-up.  I should have had 
the third reef in, but had my hands full by then.  Depending on the wave 
conditions, I only buried the rail every 3-5 waves.  We don’t have a dodger, so 
I like the “protection” of the leeward aft cockpit seat, and on the big puffs 
got sprayed, and the really big one, likely over 50, slightly hosed.  I was 
very impressed with the combings and deck design, as I watched 3-6 inches of 
foaming water flowing down the deck towards me.  C got it right, the combing 
curves, and the water was sloshed right off the boat!  I’m pretty sure you 
would need much bigger offshore waves to get any real water in the cockpit.

No I take that back!  Years ago, we were crossing the sound, close behind a big 
container ship.  I headed up to take a picture, and Kathleen calmly said “I 
think I will go straight into this one.”  Before I could say anything, the bow 
dropped about 8’ into the hole, I stepped up onto the coach-house, put my elbow 
over the boom, and picked up my feet as the wave poured over the boat into the 
cockpit.  It didn’t take long for about  16” of water to disappear, and as she 
jumped up on the aft seats to keep her feet dry, she said “Well I don’t think I 
will do that again!”  We had the companion-way hatch closed, but forward hatch, 
and the scoop vents in the head were under water and leaked.  Even years later, 
Kathleen is very good about checking that the forward hatch is dogged down. . . 
every time we go out.

Great boats!  Happy New Year, Lee
