Sabino Build Log
Landlocked:
All,
Some of you may have been following my Sabino Engineering Build Log in Steam R &D which is an amalgamation of several steam focused threads. I thought at this point, the Steam section might be more appropriate for the work on the hull. In so much as this is my third winter of work, over the next several days, I'll get the hull work caught up to date. Then, postings will slow to a crawl...
The Sabino is a 1908 steam boat designed the rivers of Maine that was later modified to work in the bays of Maine. The major modification was to add two sponsons to the sides of the hull to reduce roll and then widen the superstructure for new hull.
Sabino is still afloat and operating at Mystic Seaport in Mystic CT USA

I obtained plans from the Seaport and enlarged them to permit a 1/16 scale build. This size would be as large as I thought I could manhandle up and down my cellar stairs.

The hull lines reflect the current hull. To build it, I realized I would need to simulate building the original hull and then add on the sponsons. Here I'm guesstimating what the original lines might have looked like.

Initial phases where fairly typical. I made the backbone and then I glued the lines onto the frames. Having cracked thin frames on earlier boats, I cut the frames out solid, test fitted everything into mortises on the backbone, and then cut the frames "thin." I made a building stand angled to reflect the keel's drag to hold the backbone in a Workmate for after it comes of the strongback.

Apologies to my English teachers. I know the difference between were and where >>:-(
Since the sponson planking runs over the original hull planking, I added short "sister" frame pieces on which land the butt ends of the "original planking.

Hullo Ken.......
I am a little lost with the hull lines. :embarrassed: ...
Is the water line about the level marked BPOW..?.......
Just having a little difficulty %) in understanding how such a modification could reduce a rolling moment
