New Boat Vocabulary Word Coaming

One of the smarter things Ive done on the shantyboat, was to add a coaming around the edge of the cabin. A new vocab word for me as I slowly get all nautical during the one plus year shantyboat build:

coam·ing  

/?k?miNG/

Noun A raised border around a ships hatch serving to support the hatch covers and to keep out water. A similar structure around the cockpit of a boat.

The Glen-L Waterlodge plans didnt call for a coaming, since Glens cabin design was significantly different, and he wasnt nutty enough to consider board and batten as a cabin exterior material.

Take a look again at my wall cutaway diagram:

The coaming is the board labeled "edgeboard" against the inside edge of the side framing member.  My goal was to make sure that if water splashed up on the exterior board and batten, that it would not easily get into the boat, more so because I plan to fiberglass right up to and over the coaming.

Heres what it looked like without the coaming.

I had the lumberyard rip a few 2x6s edgewise to create the coaming. 

Of course, I epoxied and screwed it into place.

Later when we fiberglass the decks, we will create a curved filet at the inside corner and curve the fiberglass up over the coaming.

For some reason it strikes me as unusually handsome and boaty.

Roof Rafters The cabin takes shape

When we disassembled the Hollister chicken coop, we got a bunch of beautiful old 1x12 redwood siding, a shitton of corrugated metal, a handful of old dimensional redwood 2x4s, and finally, a dozen or so roof rafters, complete with birdsmouths.

True they were old and some were a little worse for wear, rotted at the ends or showing signs of termites, but most were quite usable.

This is an awesome diagram with much of what you need to know about roofs in general. Terms youll need for our shantyboat roof are common rafter, ridgeboard, birdsmouth, eave, gable end and gable end stud, ladder, collar tie, and rafter tie (also called a ceiling joist).

I sorted the good rafters from the marginal. The usable but marginal ones I treated with CopperGreen Clear and cut off the bad parts.

Since our shantyboat is smaller than the original chicken coop, I cut the rafters down to size, decreasing the overall length as well as the length of the eaves. I carefully cut the angle where they met in the center and re-cut the angle of the birdsmouth.

I laid them out on the floor of the barn, and used a temporary plywood collar tie (leaving a slot at the top for the ridgeboard) to keep everything from going wonky while I struggled to secure them into place.

With some ridiculously awkward effort, I got the two end rafters up supporting the ridgeboard.

Then one by one, I installed each of the rafter pairs.

Finally, I added a permanent collar tie to each of the inside rafter.  I suppose soon I will have to add a ladder to support the gable overhang and a fly rafter.

At the end of the day, for the first time, I was able to see the shape and size and height of this crazy boat.
