I am thinking of buying the big Hummingbird locator. A friend of mine has one and it is really a hassle to remove and take off the boat every night. I have a tiller so mine would mount on top of the area my gauges are on. I would like to build a wood cabinet to put the locator in with a flip over door. The door would have a clasp on the bottom for a lock. I understand that isn’t heavy enough to stop a determined thief but it would slow down a opportunist just walking on the dock. My question is what wood would be most resistant to moisture? The box will stay on the boat all year but the electronics would be removed when I wasn’t up at the lake. Rain & dew are the concern. The boat is stored inside during the winter. Also is there a particular stain and sealant for outdoor use that should be used?
Thanks for any advice.
