Lot of good points on both sides.
Being a bit biased, my ketch offers numerous advantages some disadvantages- some of what haven't been discussed.
1. tremendous amount of sail configurations
2. add a inner forestay - i.e. cutter rig
-makes for a "klutter" term borrowed from Fuji site, great for storm jib
3. Mule sail easily induces lean - greater water line
-a smidgen faster, upwind
4. Staysail - makes beam reach a 'blast' literally
5. Extra Sail area combined with the heavy weight enables decent to good light air performance
6. Beating hard up wind in anything under 25 knots loses against most sloops
7. Going from a racing sloop to a cruising slug (ketch) made be a much better sailor, more attuned to perfect sail trim, getting the slots right, proper draft ect.
1. relatively long keel and 3-4 sails to trim can easily balance for self steering
2. Shallow long keel offers less area for cross seas to plummet
3. Shallow draft and higher center of gravity in light air makes for uncomfortable motion
4. Mizzen boom makes a great awning support
5. Reefed Mizzen acts as stabilizer at anchor
Day sailing Notes:
1. New people to sailing have 50% more things to help with on a ketch - many like being part of the action
2. Single handed handling is tougher
3. Shallow draft allows getting much closer to shoreline
The Fuji 32 is not a Alden design, but the hull originates from the desk of Clair Oberly designer of the Mariner 31 36 & 40. The superstructure design was appropriated (& compensated?) from the Fuji 35 which Alden did design. The full cut away keel with relatively shallow draft opens up shallow water cruising grounds while the 41' mast slips under many fixed bridges further expanding the cruising grounds. Nearly as many arguments can be made on shallow vs. deep draft boats as sloop versus ketch.
In comparing two very different types of designs from the original question and the intended sailing area of San Francisco bay with some coastal hops either boat should be fine, but not discussed:
1. skill level,
2. normal amount of crew available
3. preferred weather conditions.
San Francisco Bay has 6 ft tide with plenty of depth in 80% of region, the heavier sloop is a better fit for a single hander who wants more coastal hops, ketch may be better for bay explorer with friends.
