You imply that I'm a yankee and I take offense.
Let it be known that my great grand daddy (several times back) was one of Houston's heroes at San Jacinto and I do know good BBQ. Not sure which should cause more offense. Back to the Alabama: HOW was it disconnected and reattached. The rail thing makes sense but the attachment had to be under water, doesn't it? Rather quickly is somewhat subjective, I think. Since Semmes mentions it several times, it implies that it wasn't an easy task like shoveling several hundred pounds of coal to raise steam. Granted it was new technology but that doesn't seem to be Semmes focus. I don't recall him mentioning the "why" of the removable propeller. Ray "Glenn Ashmore" wrote in message news:fvUqb.10776$62.3537@lakeread04... Don't sell us Southern good ol' boys or our BBQ short. The CSS Alabama had a retractable propeller for better efficiency under sail. (Beats the heck out of a feathering prop.) It was disconnected from the shaft and hoisted under the fantail on a rail assembly. It could be lowered and pinned to the shaft rather quickly. The Alabama had several other inovations. It could change its rig at will to disguise itself and had a retractable stack so that it could look like a pure sailing vessel.

My sincere apologies to a fellow Southerner. :-)
All I really know about the CSS Alabama was from a Revell kit I built back in the late '50s. Think I paid $.89 for it and saw one go for over $600 on ebay recently. That particular model had a reputation for being pretty accurate representation The prop had a sleeve that fit through the stern and over the shaft. It was probably pinned from the inside but I would guess that the real thing was a bit harder to fit. OTOH, as you say "quickly" is a relative term. At the time 10 knots was considered a high performance boat and 60º to the wind was close hauled so they probably had some time before the pursuer got within cannon range. I would imagine that Semmes as captain of the Alabama was more concerend with the tactics of naval warfare than the intricacies of technology. The Alabama was not so much a hybred as a hermorphrodyte. It was both a sailing and a steaming vessel. She was built as a commerce raider not a ship of the line. Had she been intended for toe to toe battles she would have been one or the other. Not both. Bringing the prop out of the water greatly reduced drag under sail but was an additional hassle for the skipper to deal with. BF wrote: You imply that I'm a yankee and I take offense.
