Hi out there good people
I've got some more silly questions, but hey, thats the joy of being the new boy!!
Firstly, where would be the best place to look for my hull fitting for the depth sounder? I've inherited an old GME unit which appears to work but reads "0" all the time. A friend suggested that the transducer (is that what its called??) may have been painted over during a recent antifoul. Murphies law being what it is I/we didnt pick upon this fact when it was out of the water for survey. The wiring disappears downwards into the hull just into the forecabin. I thought it might just go through the hull there, but after several diving attempts I can neither see nor feel anything. It couldn't go right to the bottom of the keel, or could it? I can't find anything but a few really sharp barnacles on the bottom of the keel...... Another friend suggested I could remove the fitting from inside the boat, but I have visions (nightmares) of trying to stem the inflo... None of my books mention "how to"...
My second question relates to airflo. With summer almost here and with dreams of idyllic weekends aboard I'm wondering if anyone out there knows anything about ways of opening up the cabin to more airflow either with a roof hatch or opening side windows (are they windows or ports??). I reckon something for the stove would be great. Any suggestions?
Thanks

g'day
my gme transducer is mounted next to the hull on the inside on the starboard side. it sits under the cushions and boards in the saloon. Access is simple - lift up the bunk cushion and remove the wooden board below (not fixed down - so easy) and there it is. Such a fitting would explain why you have not found any exterior evidence of one.
Alternatively, it could be that you are currently run aground in which case the depth sounder is working perfectly!!
re ingress of water for thru mounted hull fittings: purchase some wooden pegs from whitworths (a few bucks each) and tie them close to each thru hull fitting. So in emergencies should valves etc fail, you can knock the blighters into the hole and thus hold off the overwhelming forces of seawater a bit like the Welsh Guards at Rorkes drift!!

Hi. Doug.
I and my wife Janet have owned two top hats. A Mk. 2 in the mid. seventies and now a Mk.3. If you have a Mk.1 ! cannot advise you as to where to place your through hull transducer. In the Mk. 2 and the Mk.3 there is a best place. It is just forward of the galley and before the vee berth at floor level. There is normally a small removable cover over this area. Place your transducer in this place. It is mid. boat length and at minimum rocking position.
Best Regards, A. J.

Hi
I agree with everyone else on the position of the transducer, mine is aft of the head and under the saloon cushion
As to air flow, being up in the tropics (Mackay, Whitsundays) humidity is a big problem and keeping airflow. When sleeping on the boat I open the front hatch and attach it to the jib halyard, by doing that you can adjust how open you have it, particulary if raining or showers. I dont know of any top hats that have opening windows!. If you look at members photos you will see Mirandis, and either side of the hatch are what looks like white funnels, they are air vents, which swivel 360 deg so you can pick up the air flow from any direction, they open into the forward bunk so you gey a good flow of air. I also have two other spinning type airvents one over the stove and one in the head.
I find with all that and the back open plenty of air gets through.

I have a shroud that clips onto either side of the front hatch to form a funnel of sorts. Assuming you're on a swing mooring you will be facing the breeze so it pours in.
