Does anyone know what the hull thickness is in the bow under the floor access panel located in the forward cabin? I assume this is the place where everyone mounts their transducers (at least that is where mine are).
I am going to install the Tack Tick wireless system on the boat and their standard transducers are for hulls up to 2.125″ thick. Or course, I can’t measure this till the boat’s on the hard and the old ones are out (I’m not that quick). I know Pearson built thick hulls and I’m trying to preorder stuff before the boat is hauled.

Less than 2.5″. Probably around 1-1/4 to 1-1/2, depending on how low you
go.Bob

Bou you need to account for the thickness of the hull + the fairing block.
Here’s an example from some friends of mine here in Seattle.

For the speed, you don’t need a fairing block because its rotation doesn’t
depend on vertical placement. True for depth, though, as it has to point
down when the boat is at rest.Depth can be farther up the hull where thinner, perhaps 3/4″ thick, outboard
the mast about 18″Bob

Actually know what I would do.. repalce your depth sounder with a combo
Depth Speed Temp unit. One less hole.-p

Thanks Dawn and Patrick! -
I always thought the speedo would have too much turbulence to be placed so far fwd. Especially on one tack or the other. Plus the pointy end bounces so much it would be out of the water half the time.
Mine is placed deep in the bilge where it would less effected and in the water on either tack.
Just my opinion

I put the transducer in the forward cabin close to the centerline and it has worked fine for me. the hull thickness is about one inch. I have the cutout on the boat in Trinidad. Jim 424 cutter #219

My transducer is located just forward of and to starboard of the maststep.
My knotmeter (didn’t work & was very
old<http://www.flickr.com/photos/deepplaya/4869441062/>)
was accessible via the hatch in the v-berth floor. It was a little to the
port side. I removed it and glassed this closed.I was waiting for airmat’s DST900 (no log wheel, cob instrument) but it
apparenlty is on hold, so I’m going to put in the Maretron
DST100<http://www.maretron.com/products/dst100.php>I already bought at
my next haul out.-p

I know this subject is 10 years old but trying to avoid a new one. My thru-hull depth meter stopped working so thinking about the in-hull ones. So as was stated the hull can’t be thicker than 2.1 inches and I have no idea what ours is. Anybody out there can shoot me an opinion on the in depth depth meters ?
Tnx much

My original Datamarine depth transducer was mounted to a wedge shaped block of wood under the galley sink. The wedge orientates it so it’s pointed straight down. I replaced it when I installed Silva Nexus integrated instruments about 20 years ago. I figured it was more useful to know water depth in front of the keel rather than under it so I mounted the transducer up in the V-berth where there is an access lid in the sole. There was a small flat section glassed to the center-line that looked good so I glued the transducer to that spot hoping that the transducer would work through the hull. It didn’t, so I made wood wedges using teak and cut a hole in the hull offcenter next to that flat section. I find the water speed sensor to be pretty useless. It gets fouled frequently and it doesn’t tell me speed over the bottom. I know what the currents are in my area so knowing VHW, water speed, is not helpful.
I’ve always been a bit nervous about putting the transducer up there where it might get whacked by something, possibly holing the boat.
