Anybody Mounting A Compass?

Do they all have something protruding from the bottom of the hull?

i.e. If I pull the boat up on to Hobie cradles, is something going to catch on the aft cradle?

My 2015 TI has a recessed area built into the hull for a transducer. It was very easy to install a normal sized transducer into it, but a little more tricky to install the massive transducer that came with my side-imaging chart plotter/depth finder. Since it's recessed, there is no issue with cradles or trailers.

I don't know about pre-2015 TI's, someone else here will have to comment about that.

Lowrance sell a scupper transducer mount which could no doubt be used for other brand transducers. Fortunately, with a TI, I have two sets of scuppers (apart from seat ones), so could use a rear one, which never goes near a cradle. It isn't flush, but it tucks up nicely into th "vcrease" of the hull, well out of harm's way.

Your 2015 AI2 has the Lowrance ready hull, so it is a no brainer.

I have a speed puck on my AI2 where bjb mounted the Ritchie. I have an old flat, deck mount racing compass that mounts with 2 screws. I put the two small screws into the round hatch just in front of the seat, and the compass twist locks onto them. Sometimes I have it there and sometimes not.

I'll try to get a photo today and post it. Visually, it works really well. At the same time, it makes it harder for me to slide my butt forward off the seat to pull the mirage drive out, etc.

I mount the SpeedPuck on the hatch. Because of it's flatter profile it does not interfere with sliding my butt forward that much.

OTOH, the clear plastic "screen" has accumulated quite a few scratches.... from my butt or otherwise I don't know.

OTOOH, once the screen is wet, the scratches are no longer visible....and it is wet most of the time.

Another argument for a digital readout compass is that some of them are flat and a flat one could be mounted next to the SpeedPuck - facilitating at-a-glance assessment of speed vs heading without further compromise to the butt-sliding situation.

Still hung up on possibility of a latency issue though.... But, for thirty bucks, maybe I'll just try it.....

Pete, have a look at the TACKTIK digital compass. I had one on my J24 and it was awesome. Bit pricey, but you get what you pay for...

This thread has now get me thinking I should get a GPS. Anyway, here's a pic of the compass mounted on the deck hatch, with the speedpuck forward. I checked and really, I can sit forward of the seat on the space between the compass and the seat to reach what needs to be reached. Barefoot, the buttons on the speedpuck I can push with my big toe.

I like the line attachment point on the Mirage Drive plug.

Somebody suggested using a compass app in my smartphone.

Installed something called GPS Status v7.2.149 on my now-retired Samsung Note-1 phone.

Didn't work on that phone because any change in Pitch or Roll threw the heading way off..... and I was thinking "No-Go"...

But then I tried it on my new Samsung Note 4 phone and Pitch/Roll went out of the picture....it held the heading even when the phone was tilted left/right and fore-aft as it would be in my itty-bitty boat.

No way in the world I'm risking that phone on the water - but last week I saw an el-cheapo Android phone at Micro Center for under fifty bucks.

Would not expect a compass chip in something that cheap, but I have to start sniffing around in the $100 price range and see what comes up that has a magnetic compass in it.

The challenge is going to be installing the app in question to test a given phone for Pitch/Roll susceptibility... but it looks to me like there is hope there..... especially if it can handle a basic nav or mapping app as well.

FWIW, I got one of these: https://www.amazon.com/gp/product/B001Q ... UTF8&psc=1

Mounted it next to the SpeedPuck on the cockpit hatch: https://photos.google.com/album/AF1QipM ... GqoE45o2NL

Hatch still opens/closes normally.

Velcro backed up by lanyards.

Numbers could be larger... but they are readable as-is.

I like the functionality - especially when I am beating upwind to some place: trim the sail, adjust heading so telltales look right, note the compass bearing..... Then just glance at the compass every so often to make sure we are still on course. ..... As long as the wind doesn't shift, we're golden.

I use a ram mount claw and mounted a richie navigation kayaker compass. Like this i can clamp ii onto any where on the TI fit necessary.

This is how I did it, and it has been working perfect and watertight through major summer storms.
