Thanks for the thoughts. It is sounding like a loop is a good idea. The hoses are probably original, so they are worth replacing anyway. The hose I am looking at will bend to a 4.5" radius, which I think I can fit. I might have to do a 360 degree loop, but that should be OK. I'll update if...

Has anyone ever had concerns about water finding its way into the fuel tanks from waves hitting the vents? The vent lines from my vents slope directly down to the tanks without high loops. I have a water separator fuel filter, but I'd rather avoid getting water in the tanks in the first place...

We did some transmit/receive tests with the Cobra fixed radio talking to a VHF portable. At the portable, the Cobra would go from "clear as a bell" to having very buzzy interference--no middle ground--either very good or rather bad. My wife was at the radio on the boat and she said she could...

The Cobra radio is an MR_F55. It has DSC, so it has to be 1992 or newer. I'm a bit away from the Coast Guard in Montana, and I don't want to transmit much for testing, but the Cobra with the Shakespeare antenna does pull in our local NWS station better than anything else I own. I think...

As a followup report, I replaced the antenna connector and got the slightly better (but not acceptable) SWR--around 5.0. I got a jumper to connect my Standard Horizon portable to the fixed antenna, and got a 1.2 SWR. This does seem to imply that the fixed Cobra radio or its connector is leaky...

All good points Bob, as always. I just don't like to see people put all of their faith in electronic devices. I will look forward to better performance from chart plotters compared to computers. My initial experience with my Lowrance unit and the people who make and support it has been very...

We've kayaked much of SEAK for many years and I don't think I have more than 20 charts in our portfolio. And our kayak has an even smaller chart table than our C-Dory. I would just use editing software to break the charts into chunks that would fit on the kayak deck. As a person that makes my...

All NOAA charts are available in PDF format direct from NOAA. Find a place near you where architects and engineers get their plans printed and have them print the PDFs for you. We have a Selby's store in Billings that will print the latest PDF file for you for around $7.00, and that includes...

Thanks Bob. The garage is stick-built, so probably not an issue. I think I'm going to re-do or replace the connector. Shakespeare says this antenna should come in around 1.5 SWR, but, as you say, there's probably less quality control. I'm thinking I'm kind of stuck with this one, or in for a...

The antenna is within 10 feet of my garage, which could be an issue. The SWR meter I am using is for ham radio VHF, which is in the 140's mHz range, so it should be close enough. I'm going to try re-doing the connector also. Thanks for the ideas.

I just installed a new antenna on my new (used) boat: https://www.westmarine.com/buy/shakespe ... --12008215 The radio, an older Cobra MR F55 pulls in the local weather service channel very well, but the SWR is about 6.0 (not good). Shakespeare says this antenna should come in around 1.5 for...

Thanks for the comments. Now I just need to get the boat in the water to finish the project...

There is a lot is excellent information in these forums about compass location, much of it thanks to Bob W.: http://www.c-brats.com/viewtopic.php?t= ... s+location I'm trying to save some experimenting in regard to relocating the compass on my new used C-22 Cruiser. The compass was located...

Hi Wayne, I think it was your photos that I was thinking of. Nice work! I may have some detail questions when I get working on this. Thanks for sharing.

Thanks. By 10% clearance do we mean 10% of the prop diameter, or 10% of the distance from shaft center to tip of skeg? If I measure from shaft center to the bottom of the anti-cavitation plate, I get 4 5/8". That would mean that this 8.7" prop would have close to 9/16" clearance from blade...

Thanks for all the info. I think the post I was thinking of was that of an owner who created their own design, fixing the faults of the factory design. If anyone can find this one, please post a link.

I remember reading a post or viewing photos a while ago showing how a C-Dory owner had modified the dinette table and seats to be easily converted to a berth. I can't find it now. Does anyone remember where this info is or who posted it? Thanks.

Thanks guys. I see that Tohatsu makes a prop with those specs: Tohatsu Part No. 3B2B645110 PROPELLER (8.7d X 5p) 4-BLADE HIGH THRUST for $72. I have choices.

Thanks Gary. Using the calculator at http://www.csgnetwork.com/marinepropcalc.html I input this info: Speed: 6.1 mph (C-22 hull speed) Gear Ratio: 2.08:1 Prop Pitch: 5 (lowest I can find at Tohatsu) Slip: 30% (a guess) And I get 3828 RPM. The 9.8 owner's manual says that the motor...

Hello, I've acquired a 9.8 Nissan/Tohatsu 4-stroke for use as the kicker on my C-22 Cruiser. The prop and spare that came with it are identical: Diameter 8.5, 3-blade, Pitch: 9. The original owner used it to push an inflatable. Does this sound like an OK prop for use as a kicker on a C-22...
