Condensation and portlights

Cruising in the cold (frost warnings one night) wet weather confirmed the wisdom of my decision to stick with my plastic Beckson ports and install storm covers

for offshore work. The condensation was incredible. Water poured off of the aluminum skylight frames so fast that I thought the gaskets must have gone. We had to put the wastebasket under one and the stream was like a leaky faucet. I opened them up and the gaskets were dry. It was just the condensation running around the frames to the low point. I'm glad I didn't have metal frame ports doing the same thing over each bunk.

Radar

Less useful than I expected; especially for the single or short handed sailor. To get the full benifit, you need a dedicated radar watch stander playing with the gain, tracking targets, and going through various modes. Out in open water with alarms set, it is a different matter but, when landmass returns are mixed up with traffic, it takes a lot of attention to spot other traffic. Small craft don't show up well enough on the Garmin chart overlay to spot easily. You need to find them on the radar only display and then look for the little red spots. It was great to have in thick calm fog crossing Penobscot Bay when I could turn the steering and navigation over to crew and just focus on the screen but I wouldn't have wanted to be alone on auto pilot with my attention so taken up with the radar display. Very cool to watch boats go by that you never would have known about though.

Many plastic lobster boats without much mast or rigging barely show up on radar at all. The air force should study them for stealth that works in damp wet conditions (unlike the B1 bomber).

Cabin Heat

We were never cold below but, wow, is it wet cruising this time of year. I've cruised in the fall when it is generally colder but the water temperature makes a huge difference. We couldn't have been wetter from condensation if we had taken a hose to the inside of the boat. A diesel cabin heater with a flue may be next winter's big project.

Early cruising

This is a great time of year to cruise. We were in Pulpit Harbor and Somesville with just one other boat each time. We saw just one yacht east of Schoodic and it appeared to be daysailing out of Lubec. Never a problem finding a mooring although I generally anchor. No waits for fuel or to do laundry.

Roger, nice info. Some of your points are the reason we cruise in Sep. Better wind, cooler nights, warm water and rarely a problem with moorings or dockage. We tend to see more like minded people(no kids) when cruising this time of year.

I disagree about the radar though. We keep a physical watch on the bow with a horn and I use the radar display to see what my wife cannot. The overlay and side-by-side screens are very good for seeing targets and avoiding them. I do not usually need to make any adjustments to get clear views of targets. It did take a while to get the settings just right though. I used clear sunny days to get the gain and other settings to my liking so I would know how to interpret the blips when in fog or at night.

I don't think we really disagree. I didn't say it isn't useful or I regret one bit the two grand and frantic effort of getting it installed in time. It's a great addition to the boat and I'm glad to have it. I do a lot of singlehanded and essentially singled handed sailing though and I don't think the radar is going to change my practice of getting close in where most others fear to go whenever possible to minimize traffic conflicts. There is just too much for one pair of eyes to do to fully utilize the radar. The side by side screens are very useful and what I used most. I did run it constantly in the clear for familirization.

A tall blond wife who would stand on the bow with a horn for hours in the damp would be a also be a great addition to the boat and increase the utility of the radar but I don't know where to get one of those:)

Sorry, poor choice of words. I did not think you regretted having purchased the radar.

Lobster boats are a whole different challenge in the fog. They will spin around stationary and then suddenly gun the throttle. With radar, you really have no idea which direction they may speed off in. And they are certainly not looking at their radar.

The tall blond wife is a good addition to any boat and she just loves sitting on the bow in the fog. Especially when we are sailing. She also acts as lookout when racing. I would not trust that job to many others.

Radar

Having used several radars with MARPA, I wouldn't buy a unit without it. Makes tracking those targets much easier. Of course, I haven't checked the price difference. I agree that the side by side split screen is the best way to use the radar.

My Garmin has MARPA but I haven't installed the heading sensor necessary for it to function. The unit maintains acceptable overlay alignment without a heading sensor but it might be worth it for MARPA.

How well does the feature work in complex topography where there are a lot of shoreline returns?

Marpa

Shoreline returns don't seem to matter, just that the vessel target is consistently present. If the target fades then the radar will lose the MARPA lock. It seems to be able to recover if it's lost for just 1 scan, but longer than that is no good.

On a recent delivery coming into Rhode Island I painted what I thought were some anchored fishing boats. They turned out to be buoys marking Pt Judith.

The MARPA derived heading / speed can jump around a bunch if the target is not really good. I needed to have the target trails turned on to really track the vessels that day.

Roger,

Some points on condensation.

A wet bilge will lead to lots of added interior condensation when combined with humans.

Lack of intake & exhaust ventilation like solar vents or dorades will lead to condensation

LP gas cabin heaters, like the Force 10, and ovens/stoves give off TONS of moisture when burning. We always open the main hatch when cooking to move the moisture out.

With a dry bilge, solar vent and a dorade vent we have literally no condensation on metal hatch frames, port lights or anywhere on the interior even when it dips below freezing. It is a very, very rare occasion that we get internal condensation. I have spent a lot of time trying to minimize condensation and get rid of it.

The two biggest minimizing factors I've found are.. A DRY BILGE & Ventilation. Solar vents and well designed and placed dorades ROCK!!!!

One other thing that I never thought could help but does is backwards opening hatches. In foggy conditions you do not suck as much wet air in but still seem to get enough ventilation to keep the air moving.

Some points on condensation.
And very good points too.

I actually have a very dry bilge. It's basically a sump within a sump, within a sump so the water concentrates to where it can be stripped right out. Strider also has two dorade vents and more opening ports than I've ever seen on a boat her size.

The culprit in this case was temperature in the low 40's and driving rain condensing fog and fine mist right around the boat. Condensation has seldom been a problem on the boat. We were also trying to use the Origo stove to dry out some shoes and gloves.

I also have the backwards opening hatch amidships but it was too cold to think about opening it.

If I install a heater, it will be diesel with a flue.
