Much of the fleet has been equipped with this 48" wheel which allows you to steer upwind while sitting in a "tiller" position, with your back against the windward lifelines. The wheel is, arguably, as sensitive upwind as a tiller and much easier to handle downwind in waves when the tiller tends to throw the helmsman around. It's also better at the start and in close quarters maneuvering where the ability of the helmsman to move quickly from side to side makes maneuvering easier.
My family likes the security of a "sit-in" cockpit. At the dock I'll cover my jibs with a zippered sock raised on the spinnaker halyard, so the racing sails have no sacrificial UV layer to degrade their performance. When we go daysailing, there's no sails to bring up on deck, and there's no pile of four or five jibs and spinnakers down below.
As for the spinnaker, the A-sail can be loaded in a spinnaker sock to make even single-handed spinnaker sailing possible, with the addition of an above-deck autopilot.
The hardware to control the sock, but not the sock itself, comes standard on the boat and is class required. For racing the A-sails are generally thrown and retrieved out of the front hatch with all lines attached and never removed except to change sails. A retrieving line attached to the tack of the A-sail allows a windward douse which collapses the sail as it is pulled around the jib and down the hatch.
When I'm racing the additional level of control of the upper mast would be nice. When I'm daysailing, they'd be a pain. You probably make your decision on the boat based on other issues then convince yourself that having them or not is what you wanted anyway.
I'm just as glad to not have to carry the extra crew to work them. The hull molding question is a little bit unfair. Hulls after are SCRIMPed, which is TPIs process of laying up dry glass and core material, then introducing all the catalyzed resin at once so that the entire hull is molded as a single primary bond with no voids due to the vacuum.
I'm not sure if any shoal draft boats were built. The boats are designed so the righting moment of both configurations is the same, although the deep draft enjoys and advantage upwind in light air.
Most fleets have standardized on the deep keel, while the Chesapeake Bay Fleet has gone shoal draft, as are many of the Florida owners. Also this probably understates the A-sail's size advantage over a traditional spinnaker. Taken together this is probably the difference in a boat that will plane on a reach, and a boat that will only surf downwind. Also you'll need the bunks for those 10 crew members. When will someone design a boat that can be effectively raced with only the number of people for whom there are bunks?
They basically say, "You can't change the boat unless these rules specifically allow it, period, the end. I believe approximately boats have been made since its introduction in or approximately 25 hulls per year.
I hope this biased view was helpful in outlining some of the issues and tradeoffs between these two great boats. I'm just suggesting you also look at their latest successes In both hand lay-up and vacuum bagging the initial process is the same. The fiberglass is laid up and wetted out by hand. That is, gel coat and other "liquid" layers are sprayed into the mold and allowed to cure until tacky then layers of laminate fiberglass cloth of different types are hand "wetted" or saturated with resin which already has catalyst in it and laid into the mold.
The cloth is smoothed with squeegees, and more resin is added until the cloth appears to be completely and thoroughly wet through with resin. Any dry spots result in voids which can blister and provide no adhesion between the laminate layers. This process continues layer after layer, until the entire "outer" hull is finished. That is, their resins "co-mingle" and harden as a single structure.
I do not know if this can all be done in one day. After the outer hull is laid up, sheets of balsa coring are fitted carefully into the hull. I imagine these sheets are compressible, so they are just tightly hand laid next to each other, while the outer hull is still tacky.
After this the "inner hull" is laid up over the core material using the same process that was used on the outer hull. Again the laminate layers are saturated with resin until completely wetted out.
Some structural stringers may be laid into the hull near the end of this process, but most interior structures are added after the hull "shell" is completely cured. At this point a hand-lay-up hull is left to cure. After it is cured, it is removed from the hull mold, placed in a rolling jig, and moved into the assembly process where additional structural components are added, etc.
With vacuum bagging, when the last of the layer of laminate has been added to the inner hull, the entire hull is wrapped with plastic and a vacuum is applied.
As the air is evacuated from the bag, the external air pressure squeezes the laminates together. This applies uniform pressure to the laminates and I think may result in "squeegeeing" some of the surplus resin out of the uncured sections of the hull. This is captured by a filter at the vacuum points. As I understand it, pre-cut and stitched laminate layers are placed in the mold DRY.
Other cruisey features include Volt electrical system, below decks linear drive autopilot and many other nice features that would make her ideal as a family day sailor, but she is so nice that the serious racer would do well to buy her and tweak her to be the best of the race course. Awlgripped in and not a mark on it!
Sail Magazines "Boat of the Year" when introduced in ! Her large cockpit makes it pleasant to take a good sized group out for a day sail and the wide ranging popularity has made the design one of the most popular class race boats ever! Accommodations: Starting forward is a V-berth with storage under followed by Head to Port with manual W. Opposite is a hanging locker. Forward is the Nav. Station to Port with flip top chart table while to starboard is the galley with single burner alcohol stove, stainless sink with manual fresh water, and storage.
Chilled food stuffs and beverages are kept in a 54 quart cooler that stows behind the companionway ladder. Headroom below is 5'-4", 2 opening hatches and 4 opening ports. Of note, the owner has varnished all teak trim below vs. Edson pedestal steering. Wide side decks lead fore and aft with double stainless steel lifelines, stanchions and bow rail and stern rails. There is a centerline gate at the transom. IJPE : Hall spars tapered, fractional rigged, aluminum mast with white Awlgrip finish with rod rigging.
