P30 Head Vent

[Steve Mosher]

HI, I need to install a vent for the head and I want to put it directly
above. Aft of the fresh water supply.

Does anyone know the distance between the top of the cabin through the
liner ?

THanks In Advance

Steve

[Robert Franklin]

Do I notice correctly that you have not had any answers to your question?  Or is my email system not telling me the whole story. 

 

If a guess is enough for now, I can give you one.  Figure 3/16 for each skin and some air between.  I would say if you figured on 1/2 to 1 inch you'd be OK.  Don't the vents have considerable room for adjustment?

I'm not 100% sure I understood the original question.  The way I read it, you were asking for the thickness of the cabin top from the top through the liner.  I do not know what it is near the head, but next to the main hatch, it is about 1.25".  I know this because I am re-mounting my rope clutches, putting them on 1/4" pads and running them that leaves about 1/4" to 3/8" of the 2" bolt still sticking through.

I suspect the roof has balsa as well.

 

 

Dick Usen

[Jeff Griglack]

Yes, definitely, the roof has balsa, unless you get too near the mast step where it is plywood instead of end grain balsa.

There is core and overall thickness is on the order of 1 to 1-1/4" for outer skin (mat/roving layup + gelcoat), balsa core, inner skin (chopper gun layup - you bet it is), headliner (chopper gun layup).  There is typically some gap between iiner skin and headliner and the thickness of the inner core and headliner varies quite a bit since it was made by chopper gun. 

 

I have some photos of a vent cut-out hole on my 10M.  The construction would be pretty similar with the P30.  Photos are here:

http://www.pearsoninfo.net/10m/tmp/

 

I reseced the balsa and back-filled with thickened epoxy.  I also filled the gap between the inner skin and the headliner.  No photo of that?

[Eric Reuter]

I'm planning to install a vent in my P30 head as well. I think that
I'll center it on the ceiling, just in front of the mast. Anyone see
any issue with this placement? It is more curved than the Nicro
instructions recommend, but I figure I can build it up with epoxy if I
need to.

Just have to find a damn 4-3/4" hole saw. Probably going to cost me
more than the vent.

Eric

[richard usen]

You may have a structural issue if you cut it too close to the mast. You
could cut the hole w/ a saber saw.

[Eric Reuter]

The structural issue is my concern. It would probably end up being a
foot or so in front of the mast.

Anyone done this?

Eric

[richard usen]

Why do potential damage to the house? You already have an opening port. It's
another thing on the roof to snag sheets and trip over. I put a cowl vent
over the rope locker which works well. I wish I'd located it further away
from the anchor cleat so I could have mounted a second cleat. Instead I had
to mount a Sampson post.

[Eric Reuter]

I want active ventilation when I'm not on the boat to keep it dryer.
The solar vent pops out and there is a flush plate that goes in for
sailing (or at least for racing). It would be aft of the shrouds, so
I don't think sheets should be a problem. The biggest risk would be
that it would get trampled by the foredeck guy when he rigs the pole.

Also, when we sleep in V-berth, smelling the head all night is a
drag. I'm trying to induce airflow in the opposite direction.

I do appreciate your keep-it-simple approach, but I think the boat
would benefit a lot from better ventilation.

Eric

[richard usen]

If you have head odor that's more than the hatch can handle, you have a
different problem. I just got done replacing all my hoses and removing the
wye valves. And, there had been no odor before once I fixed the leak at the
holding tank.

[Eric Reuter]

I probably should replace the hoses, but I don't have a holding tank,
and know that I need to install one one of these days, so I've been
holding off on buying hose that I might not be able to use down the
road. The LectraSan is actually under the V-berth, which probably
doesn't help.

It's not terrible, but you can tell it's there.

Eric

[richard usen]

Sounds like that's the problem.

On a different note, I need a free ad here. My wife has fallen in love w/ a
beautiful boat and wants me to sell our pristine 1979 P-30. We've only been
married four years so I have to keep her, so that isn't an option.

You're on the right track, but there is an occasional better boat. This
happens to be one.

[richard usen]

No, actually a better boat. After having done everything possible to the
boat, I'm hesitant to consider starting over w/ another, especially at my
age, but even geezers need long range plans.

Mark your hole, drill connect and file.  You probably won't sleep nights remembering that the hole is hot perfect ... that would be my problem.  But if you're like everyone else and you remember that the hole will nevrer be seen again its probably as good enough.

4 inch hole saw? Expensive? Yes. Maybe this group should by one and share it around.  Good for all the old style instrumentation, Signet, Standard, etc.

Dick,
Decisions, decisions, decisions...
I'm lucky. Weatherlight is Dawn's boat! All I have to do is maintain her (actually, I have to maintain both "her"s; Dawn and the boat)

Tell us what Judy's fallen for.

One sugegstion: tell her something like this "Oh, those _______________ don't sail worth a damn. Can't get 'em to heel at all."
Go for a test sail on a blustery day but keep cracking off so it won't heel. Then you could add "Don't point worth a damn, either."
that should do it :-)

Great idea. I just suggested that I'd need her help every spring w/ varnish

[Peter Ogilvie]

It's a Swan 43 if it's a '69. Probably the best all around boat that the S&S/Swan collaboration produced. I've lusted after that boat since the first one showed on the market. The Tartan 41 is a poor man's version though not an identical design, for one thing the Tartan was 'sposed to be lighter.

I'm not too afraid of the quality of the hole keeping me up at night.
I'm really most concerned about whether making a hole 12 - 15" forward
of the mast is going to have any structural consequences. My
assumption is that the downward force of the mast is primarily carried
by the compression post, and that the coachtop isn't really
contributing much.

Another place I'd considered putting the vent, where there would be no
structural concern, is in the companionway hatch cover. It obviously
wouldn't do any good when it's open, but it isn't needed then.

I've ordered the 4.75" hole saw. This is the size required for the
Nicro 4" vents, deck plates, etc. If anyone needs it when I'm done,
I'm happy to lend it out.

A vent in the forward hatch is an idea. Make sure you have a way to seal it
off if the hatch is open as a wind scoop. I made a screen for the forward
hatch w/ a pair of wings that really blasts air down below. Don't forget
about headroom. I keep slicing my head open, most recently yesterday. I hate
it when that happens.

[richard usen]

Actually, this is a very complicated decision. The $$$ is a major negative, but almost equally important is the work issue. the 30 has a tiller and all lines to the cockpit including reefing. And the boom is short and easy to furl. Its an easy boat for two elderly people to sail and put away. It has limited storage space and tankage so is really only good for weekending. But, the concept is sure inviting. The new boat has a wheel and every string at the mast, so it isn't a good single hander. I suppose I could tow a dinghy w/ a 30 gallon water tank....

I wouldn't worry about the structural effects of a hole in the cabin top in front of the mast.  I would be vry concerned with the type of vent you install.  A standard cowl vent that sticks up 6-10 inches will catch every jib sheet that comes its way and remove the vent in the blink of an eye.

 

I'd strongly suggest if you install the vent in that location that it be a simple mushroom vent perhaps even one with a fan in it.  The mushroom vent won't catch lines.

[SteveM]

Hi Bob, looks like the vents allow for up to 1" of hull thickness. I'm
not sure what the thickness is. I'm looking to see if I can put it as
far to the rub rail where I think the liner ends before the top gets
bolted to the hull. I think the balsa core is just on the top.

I do have a head odor problem and the po just ran a clear tube from
waste storage to the scuppers. This hose was plugged with bugs and
other stuff so I figure I'd run a short hose close as close as
possible top off with a fuel vent.

Thanks for your reply, and I loved your reply on removing the
bearing..

Thanks, Bill.

The vent will be a Nicro Day-Night powered type. The vent assembly
pops out of the deck plate and can be replaced with a flush plug while
sailing. It will be aft of the shrouds, so I don't think sheets will
be a big problem. I just worry about it getting trampled when the
foredeck crew sets the pole.

I had the privilege of taking care of one for a busy Surgeon for 3 seasons
on the North East River head of Chesapeake Bay. Not much more than a
weekender. The 32 is a gem I saw one last year at our boat show on Trail
Creek in Michigan City Indiana.

Great day sailor, all lines led aft and a self tending jib. Tacking was
breeze just put the tiller over and she turned in her own length.

Unless you have the screw in type cowl vents you have to put a leash on them if you want to keep them.

 

Bill Robart

[Bill Robart]

The mushroom vents don't neet to be removed when sailing as the lines won'tcatch on them if the bottom of the vent is flush with the cabin top.  My dorade vent is well aft of the forward lowers and at the very edge of the cabin top and the cowl vent still catches the jib sheet every so often.  Fortunately it's a screw in vent so it doesn't go swimming.

I have been planning to add two dorade boxes to vent the main cabin better, however, the holes would be aft of the mast somewhat (haven't really looked at this in all that much detail yet).  The idea is not to vent odors, but to vent humid air better and take care of the mildew.  With the head door open, this would also take care odors from there.  Moving the vents aft, a little, eliminates the structural problem around the mast, and eliminates problems with the jib sheet.

I just looked at my boat w/ the idea of having a vent forward of the mast.
This will no doubt be in the way of people working at the mast. All my
strings end in the cockpit and I rarely have the wind aft to fly a
spinnaker, so that wouldn't be an issue for me. But, I hate to crud up a
good working area w/ a toe-stubber. Be careful.

Dick-
The vent pops out, and comes with a flush plate that goes in while
sailing, or at least racing. So there won't be anything to trip over.

Eric

[richard usen]

I assume it still has a flange on top of the house. Think about it long and
hard. I'd start w/ a cowl vent over the anchor locker and see if that does
it. My boat doesn't seem to need anything more than that and the two stock
vents back aft.

[rob sweet]

I pulled the air cleaners off of my MD 11 for the first time to clean them and was surprised to find that they don't come apart.  It looks like the filter media is fine wire mesh.  From what I have read (which is sometimes suspect) you just soak the whole thing in diesel fuel, blow them dry and treat the element with some thin oil.  Does this sound right?  Thanks. Rob

[cap...@comcast.net]

I'd start with a new one then follow the directions. You have no way of telling how old ( or degraded ) it is.

Rick EP

[Dan Pfeiffer]

Getting new ones is not a likely prospect on this engine.  The units are really more silencers than filters.  The wire mesh will keep thnigs bigger than marbles out.  That's the way they came.  They are pretty effective as silencers.  Having one fall off while the engine is running will show you that.   You have described the cleaning method outlined in the MD11 instruction book.  In addition to that book I have some service manuals in PDF that I can send you it you want. 

 

Dan Pfeiffer

[richard usen]

Why would you need an air cleaner on a boat? You're not taking in dusty air. What you need is a strainer to keep the bugs and rags out and maybe something to tone down the noise. My snow blower doesn't have an air cleaner in the winter, only in the summer when it runs the mower deck.
