Advice needed on dehumidifier
We are planning to leave Bessie, our NT32-238 on the hard north of St. Louis, MO, for the winter. This will be the first time that we have left a boat for the winter are are seeking advice on winterizing, especially the need for a dehumudifier. We understand the need to blow all of the water lines clear, and we have an air compressor aboard.
Many thanks,

For the last ten years, we’ve been using a stainless steel Mermaid unit - works very well. It’s a bit of a beast to store in the engine room when not in use.
Pricey though - but it’s for your beloved tug, so simply insert a low impedance source of funds.
I set it on the galley sink on a modified drain board and let the water drip into the sink.
Happy tuggin’

Currently cruising Salt Spring Island. Just fueled up in Sidney BC Canada for $US 4.26 a gallon!
Here’s a note from Mermaid a few years ago - price has likely gone up:
Our horizontal 120 volt dehumidifiers are $830 each. Horizontal dimensions are 7.5" tall, 12" wide & 13" long.
It can be built in 220 volt for an additional $140.
Shipping ($40 anywhere in the continental US) and tax (only if within Florida) are extra.
Our units are stainless steel construction and include a 5 year factory warranty.
They weigh 36 lbs.
They take 3-4 days to build and 2-3 days to ship.

Each winter I put a "big box" store (like Home Depot) 30 pint dehumidifier in the galley with a short hose attached to the built in hose drain (that bypasses the storage tank) for continuous operation. If worried about the boat becoming too dry, install a timer to set the number of hours you want it to run. Also, you can use a "humidistat" or measuring device (I used a home "weather station" for a humidity reading and temperature reading) to monitor internal temps and actual humidity.
This system worked great, coupled with an oil pan heater on the Cummins engine that kept the engine warm and the entire ER warm and dry (no rust problem at all). I kept the ER hatch open to aid in circulation of air.
In my last year of ownership, I also used the same type of dehumidifier in the head draining into the shower (no space on the small counter to drain into the sink) and into the sump. Head door tied open against the stairs. This helped move throoughout the entire boat. All windows and exterior hatches closed.
One of the dehumidifiers was over 10 years old and still worked great.
You do need access to "shore power" for this to work, but it does work very well keeping the boat dry and free from "boat odours", at least in my experience.
PS. I live on the BC south coast where it rains most every day in the fall, winter, and early spring with outdoor humidity around 90% plus most days. With this system, interior humidity was around 40% and was fairly constant.
Hope this helps,
