The dining room/kitchen doghouse on the Irvin and Miller (her sister) have a forward winch area to the rear of the doghouse. Together they are quite large and really stand out in any photos also showing the narrower telescoping hatches fore and aft of them. Don't know about the "sister boats" of the Roberts having a doghouse, but there is no doghouse in the Erie dock picture, just a forward winch in that spot and glare of the sun on the flat deck. Those that can enhance or blow-up the Erie picture will see a big old steam winch, one up forward and one aft on her deck.
What I did find out and can clear up is the number of hatches on Percival Roberts Jr. and Alva C. Dinkey had at birth: According to "Greens Marine Directory 1916"; The Dinkey, built in 1909, and the Roberts, built in 1913, were very similar boats. Both where 580'long, 58'wide, 32'draft, 3 holds, and identical triple expansion engines with Scotch boilers. The Dinkey had hatches and hold tonnage of 12H/4000T,12H/3400T,12/4100T=36 hatches/11,500 tons capacity when built. The Roberts had 13H/4100T,12H/3200T,10H/4400T=35 hatches/11,700 tons capacity when built. In later "Greens pubs" both boats, in mid-life, had there boilers replaced w/Water Tube Boilers. The Dinkey in 1943 (mfg. date) or after, changing her numbers to 12H4000T,12H/3300T,11H/4000T= 35 Hatches/11,300 tons (1H and 200T less). The Roberts in 1946 or after, changing her numbers to 11H/4200T,12H/3400T,11H/4100T=34 Hatches/11700 tons (1H less, but same T). It appears the shipyard learned over 3 years that by reconfiguring her holds, the Roberts wouldn't loose any shipping tonnage like the Dinkey did when converted. It also appears the Water Tube conversions were possibly heavier and required more space than the old Scotchs, because both boats lost a hatch. I wonder if these changes are true with all the other boats that had the same conversion. I'll bet the relocation of the rear masts from behind the stacks to in front of the stacks took place at the same time. Location of the rear mast might be, at a distance, a visual sign of a boiler type or change on old boats. Both boats being the same size, with the Roberts being able to carry more, I don't think she was designed for or ever had a doghouse or extra guest quarters. I think the reason for one less hatch at birth than the Dinkey, is the designers increased the narrow space between hatches by as little as 3.5 inches, 34H x 3.5"= 109", 1H = 9' or 108"+ 2 edges. I'm guessing the confusion about the number of hatches in later life, is nobody did a Arron Rogers (double check) after 1946 or just looked at her (like we have), but being lazy used builder's data.
Still need advice on how to enlarge, enhance, zoom-in or clean up old web pictures like the Roberts? Any help appreciated.
Thanks in advance.
