I had a question from Dutchess on which is better AIS A or B? I'm going to reply in a post instead of directly to Dutchess since the subject may be of interest to others.
If you want to participate in AIS (Automatic Identification System) you have several choices:
You can chose to just receive AIS signals from other boats and not transmit your own position. This is the least expensive option. You will need an AIS receiver such as AMEC CYPHO-150S for $259. It has an internal signal splitter so you can connect it to your VHF antenna on top of your mast for maximum range.
If you you want to transmit your position so others with an AIS receiver can see you (such as very big ships) then you will need either a Class A or Class B transceiver. Class A is for the big boats, it transmits more often and with greater power but it costs more, around $1700. The AMEC CAMINO-701 is such a unit. Be aware that the $1700 cost is only the tip of the iceberg. You would need a heading sensor, GPS antenna, a VHF antenna, a junction box for interfacing with on board equipment, it costs more than the $1700. Only big ships have them installed.
If you want a simpler solution to transmit an AIS position and also receive AIS info from other boats you can chose the CAMINO-108S Class B transponder for $649 (check the box with the integrated splitter). It comes with an internal GPS receiver but requires an external GPS antenna which you can get for $49, the GA-22. Just connect the external GPS antenna, split the power to your VHF radio and route the VHF antenna wire from the mast to the unit. No separate antenna splitter is required. Note, the antenna splitter is an active splitter. It does not introduce signal loss like a dumb splitter. It switches between the AIS transponder and VHF radio in real time with the VHF radio taking precedence if there's a conflict.

Poughkeepsie Yacht Club - At home on my dock, last post until 9/15/2017
This looks very big when passing close by! |
The boat at the left edge got my attention! |
Along the way we passed three naval vessels that were apparently in town for the Memorial Day weekend. One was an aircraft carrier, very impressive when so close. I can also vouch for the effectiveness of having AIS displayed on your chartplotter. At a glance you can see which very large boats are anchored and which are moving, very important when running through New York harbor. All the ferries have AIS too. Most chartplotters will give you a choice on how to display other boats on AIS. For me I chose the option of projecting a line where I will be in 10 minutes and the same option for other boats. If the two lines intersect, then you have a problem to solve to avoid a collision. Furthermore, there are two types of AIS. Class A just receives signals, Class B will not only let you see other boats AIS signal but it will also transmit your own position so you're visible on their AIS displays. I have Class B, everyone should. If you want to use your VHF antenna at the top of your mast (for maximum range) then you will also need an active splitter which automatically switches between the AIS transponder and your VHF radio with no signal loss.
I was a great cruise, now it's time to get ready for the fall and our next trip down the ICW |
So this is my last blog post until 9/15 when I hope you will join me again for another trip down the ICW to Key West Florida. There may be a vew interim posts when we take our four grandkids for a Long Island cruise, we are looking forward to that as are the kids. Thanks for reading the blog, it's been fun.

Atlantic Highlands - at anchor with cold and rain for comfort
A second iteration of the iris - I like it better than the first one |
Tuesday is predicted to be a better day as far as visibility, the temperatures will still be in the 60's with an overcast sky, ugh. The only good thing is the flood tide that should carry us far up the Hudson River in the morning. If you can catch the flood tide at the Battery in NYC, then you can ride it up the river all the way to the Poughkeepsie YC. This only works going up the Hudson since the flood tide is progressively later in the day as you move north.
Nobody left today, we're all in a row |
Once again we plan on leaving in the morning in anything other than a downpour. We've given up on getting warm weather but we do want to avoid rain going through NY harbor.

Atlantic Highlands - at anchor
Goodbye Atlantic City until next year |
A great dinghy dock at Atlantic Highlands |
The moorings here are $50/day, way overpriced. As usual, we opt'ed to just anchor which we prefer to a mooring anyway. There's room for at least a dozen boats but there are only four of us here tonight. There's a 15 minute (time limit) dinghy dock down the second fairway past the fuel dock. So we have everything we need in an anchorage.
Lots of room in the anchorage, why pick up a mooring?? |

Atlantic City - at a dock by The Golden Nugget
The marina was full! |
The entryway to the Golden Nugget |
There's a pool on the 6th floor, available to boaters too, cool today though |
I bet Finn and Rowan would have lots of fun with one of these in the house! |

Cape May - Last day
The dredgers are still squatting in the favorite anchorage in Cape May, but a few boats are still anchoraged |
We're having spring tides and the lows have been -0.8 ft! In walking Hoolie today we saw one boat in a place where we've anchored before, it's shallow. The big power boat (see photo) was hard aground and had called BOAT/US for a tow. When you anchor, all you really have to do is to look at the nearest tide station and subtract that number from whatever depth reading you see when you anchor. If the resultant number is less than your keel, then you will be aground. How difficult is that? I went out tonight with Hoolie and the boat was gone.
Let's see, if you keel is deeper than the water, you're aground! |
If all goes according to plan, we'll shove off for Atlantic Highlands on Sunday morning for our longest trip of the cruise (if the forecast holds).

Cape May - We explore Cape May shores
We actually saw the sun today so we visited the lighthouse/ |
If you take the round the Cape route on the inside, you'll have to contend with the standing waves |
There is not 55 ft at high tide, but the formula given below works |
As an example, when I came through on Tuesday the tide was at 1 ft above MLLW as given by the tide station at the western end of the canal. The NOAA actual vs predicted gave the result that the actual tide was 1 ft above predicted so the equation yielded: 58 - 1.0 ft tide - 1.0 ft actual vs predicted = 56 ft. With my 55.3 ft mast I had plenty of room, over 1/2 ft! Just to keep things interesting, the height boards were unreadable for the bottom half due to scum and several were broken off below the 52 ft mark. No problem, I've been through here a dozen times and my formula has always worked.
There's a great fish market over at The Lobster House, we crab stuffed flounder tonight with stuffed clams |
The winds on Friday are close to 20 kts all day so we'll take yet another day off and start north again on Saturday for Atlantic City and hopefully for Atlantic Highlands in New York Harbor on Sunday, if the weather holds.

Cape May - Rained all night long, cold today
Paul May is a dependable diver in Cape May - he's a local |
His truck is the equal of any machine shop - amazing |
Goodbye Paul, I hope I don't need you next year but it's good to know you're around |
The storms just keep coming at us. The first bleak window of opportunity looks to be Saturday and an outside change of a trip from Atlantic City to Atlantic Highlands on Sunday. Unfortunately, this is Memorial Day weekend and the marina at Atlantic City does not honor my Marina Life discount and on top of that they raised their rates for that weekend from $3/ft to $4/ft! Regardless, we need to head north sometime and if the weather allows it, we'll be there Saturday.

Utsch's Marina in Cape May - at their dock, dredgers and more dredgers
Utsch's has their own dredgers to keep their water level good |
Here's the next size up for more serious work |
Finally, here the anchorage hogging dredgers by the Coast Guard station |
Still, we're happy here in a slip normally reserved for locals due to demand |

Cohansey Island - at anchor
Hoolie's beach - for some reason he was very interested in that patch of seaweed |
On top of that it was hard to see forward in the downpour and sure enough, we snagged a crab pot buoy that was attached to a toggle (a two piece affair with a rope between the buoys, great for trapping a propeller). Most of it came off but I'm sure there's some left attached so I called for a diver at our next stop at Utsch's Marina. We were referred to a diver that thought it was a real imposition to actually have to dive. He wanted $350 to get his toe wet and then he was on an hourly rate with the minimum charge being one hour! We about choked on that and said, "No thanks". We're used to the southerly rate of $40 to dive to fix a fouled prop or replace a zinc.
The boat behind us search around for awhile but finally decided to anchor near us as is often the case |
Coming into the anchorage is where I picked up the buoy. It was raining hard and I was having a hard time seeing anything. Ann and I heard the unwelcomed clunk of a buoy hit and feared the worse (go set the anchor before we drift into shallows). However, most of the buoy and line came off and we found we still had forward motion. So we anchored and placed calls. I very much doubt that everything came off, it's not been our experience in the past with encounters with lobster or crab buoys. With a long trip ahead of us to PYC still, we need maximum speed.
Tuesday is also not such a wonderful day so we'll leave at 7:00 am and try to get into Cape May by noon so we can get under the 55 ft bridges in the canal. There appears to be a very narrow window to reach Atlantic City on Wednesday afternoon before the weather closes in again with high winds and waves. If the window stays open, we'll depart for Atlantic City Wednesday around noon and wait for a window for New York.

Chesapeake City - Last day
Ann's painting of the day |
Yesterday's painting |
At anchor, we see the sun for the first time in three days! |
We still plan on overnighting at Cohansey behind the island before moving on to Cape May on Tuesday. However, it looks like we may be trapped in Cape May for several days as a front moves through, we'll see.

Chesapeake City - Waiting for weather at anchor
Pretty house but lots of company with the overhead bridge |
Meanwhile, Ann painted and I worked on the 2017 edition of my ICW Cruising Guide. It will be greatly enlarged over the 2016 version with more chapters on what we've learned over the past 35 years of boating and the this year's best routes through the hazards of the ICW.
Good dinghy dock |
Quite a difference from last night when we were one of only two boats |

Chesapeake City - at anchor (oops, forgot to hit publish button last night)
There are only two of us here tonight |
Here's the reason there's even 4 ft at MLW, note the number "6" at the bottom left. He keeps the 4 MLW channel open |
The problem I'm told are the barges that come by in the canal and wash in silt into the entrance. The anchorage itself to the east of the entrance is not affected. The connection channel by the two ACOE boats is affected with only 4 MLW. We only draw 4 ft 9 in so with a 1 ft tide, we're fine.
There's a very nice park on the eastern end of the anchorage, great for walking Hoolie |

Annapolis - at a mooring
The mooring field is as crowded as ever, what a change of pace from the anchorages of the last two days! |
Hoolie relief is nearby, we use the northern dinghy dock, not the one down Ego Alley |
The "Sandbagger" racing class modeled after the original oyster boats of the Chesapeake. Sail area was not controlled. |
Nice sunset at Annapolis |

Solomons - at anchor
A fishing weir - no passage, many are 100's of ft long |
Off our aft at Solomons anchorage |
A view of Fleetwing and the anchorage |
On Thursday we're headed for Annapolis and a mooring. I think I owe Ann a painkiller at Pussars. From there we head for the Chesapeake City anchorage and see what develops for weather for going down Delaware Bay.

Mill Creek - at anchor
There's a out a dozen boats in all scattered around the anchorage, still plenty of room |
Typical house along the shore, secluded |
This leg of our trip is our anchoring leg and tomorrow's goal is Solomons in the anchorage by the Holiday Inn. We plan on leaving around 8:00 and we're expecting a crowd at the anchorage given how many boats we saw today. Everyone was backed up due to the windy conditions earlier but the rest of the week is predicted to be relatively calm, I sure hope so.

Hampton - Making plans
Nearby condos on the water, our morning walk path |
A view of the marina from the nearby bridge, it's not very big but we've always been able to get a slip |
The other great convenience here is the Enterprise office about 100 ft away and their $10/day weekend rate which we just took advantage of. However, it's time to go and Tuesday is our day for departure.

Hampton - Mariners Museum and Park and Dinner with friends
The last surviving example of a figurehead by John Bellamy, stunning in person |
I cannot imagine the noise this cannon made when fired in the confined area of a ship's hold |
You meet great sailors along the ICW - lifetime friends. |
