I think that a tabernacle on a modern
sloop over 25' would'nt make much sense. On such a rig you will probably have to remove the sail and boom, making it alot of work just to go under a bridge. Also with the mast being so tall, you would have to disconnect it from the tabernacle because it would be sticking out two far to travel much on the inland waterways. It would also be difficult to lower such a long spar from
deck. However for a boat like the Amphora (you can see pics of her rig in my albums), that I rigged as a gaff
ketch motorsailer with both spars on tabernacles, they are great. On one trip north we lowered the mast on the
Hudson, raised them when we got to Oswego, had a great sail across
Lake Ontario (yes she would sail off the wind), and lowered them the next day to go into the Trent-Severn waterway. I designed the rig so that I did not have to remove the
mainsail, gaff and boom to lower the main, and It could all be lowered from
deck.
