What are the advantages of a catamaran split hull design compared to traditional monohull boats?
A catamaran split hull design offers advantages over traditional monohull boats in terms of stability, speed, and interior space. Catamarans have two hulls, which provide better stability and reduce rolling motion in rough waters. They also have a shallower draft, allowing them to access shallow waters. Additionally, the wider beam of a catamaran provides more interior space for living quarters and amenities. Overall, catamarans are known for their efficiency and comfort on the water.

What types of sailboats can travel the globe solo?
Monohull, catamarans, and trimarans.
The disadvantages of sailing a trireme?
They don't point well to weather. When they capsize they don't come right side up on their own like a monohull. You need to enslave at least 100 oarsmen if you want it to go anywhere. I'd recomend a small sailing dinghy or catamaran by Hobie Sailing. Do you mean Trimaran? A trireme is an ancient Greek/Roman warship that was oar driven!

Why has the America's Cup gone from a mono-hull to a multi-hulled vessel?
Best i can tell Allinghi cheated by using american sails in the 31st and 32nd races. Then got cocky and refused to race a monohull in the 33rd race as defenders and now tradition and real sailing are most likely gone forever from the America's cup. Might as well program the ugly things some people refer to as boats to sail themselves. Then forget about real sails, rails in the water and beautiful boats.Perhaps more concisely: A reduced drag coeffiency rating means less wind to propel the craft at an equal rate of speed, regardless of perceived beauty; oh voice of envy.
Will a fast ferry make you more seasick than a conventional ferry?
The answer is: sometimes yes, sometimes no. The chief advantage that high speed ferries have over monohulls for minimizing sea sickness is that they make crossings much faster than traditional ferries, therefore limiting passengers' exposure to uncomfortable sea conditions. Whereas monohulls are more comfortable in head seas (seas that run in a direction opposite that of the vessel), catamarans are often more comfortable in other sea directions. Catamarans are particularly uncomfortable when running into a sea on the forward quarters (seas that face the vessel, just at an angle to either side of the vessel). HOWEVER, catamarans are often now equipped with something called ride control that can smooth out the ride to the point that it is better than a monohull in all conditions. Ride control is typically actuated flaps, one per hull, most often hanging off the stern(s). Because there are two hulls to attach these flaps to, spread a good distance apart, the ride control flaps are very capable of keeping the roll of the vessel flattened out. Additional ride control elements now often on high speed ferries are "T-foils", inverted Ts hanging from beneath the forward portion of the catamaran hulls. In combination with stern flaps, passengers are granted a pretty smooth ride in even harsh conditions. So, in summary, catamarans have a better chance of limiting sea sickness primarily through the shortening of time that one is exposed to uncomfortable seas. However, if there is not ride control, catamarans can still deliver as, if not more, uncomfortable motion as monohulls depending on sea direction. Also, more important than type of vessel is the route of the vessel. There are many situations where monohulls run on more protected routes to the same destination of a high speed ferry and therefore are simply challenged less by mother nature. Good luck!
What is tender assisted drilling rig?
TADs were the rig of choice in the 1950s and early 1960s in the GOM for development drilling off fixed platforms. However, the monohull tenders tended to lose location with mooring failures during storms. This occurrence, along with severe motions of the tender, resulted in their losing favor, except for use in very mild or benign environments, such as in the Far East and West Africa. There are about 25 TADs in existence today, with most being monohull tenders. Four are semi tenders and offer the motion characteristics to drill in mild to somewhat severe environments. The TAD advantage is that its DES is relatively lightweight, one-quarter to one-fifth the weight and one-third the space of a standard platform rig. Most TADs carry the DES on the tender hull and are self-erecting, so no workboat or derrick barge is required. They are particularly attractive for situations in which there is an old platform with reduced load-carry ability and/or space, such as when a platform was drilled with a standard platform rig and then production equipment was loaded onto the platform, thus eliminating space and load-carry capacity. It is not unusual for a platform to deteriorate with age and then be unable to hold up a standard platform rig when additional wells need to be drilled. The TAD is an option for this situation. Of course, if the platform is in jackup water depth range, the jackup may also do the drilling if its cantilever can reach the well centers with adequate load capacity and if there are no incompatible spud can holes and/or a severe punch-through condition. For spars and TLPs in deep water where weight and space are at an absolute premium, TADs, particularly semi TADs with their lightweight DES, have significant advantages in some cases over a modular platform rig. This is usually true for spars and TLPs with > 9 or 10 wells up to a maximum of ≈ 24 wells. For spars and TLPs with < 9 or 10 wells, their load and space availability are too small for any type of platform rig or DES, and those with > 24 wells are large enough to support a modular platform rig without a large weight and space penalty assuming all other factors are equal. Semi TADs also have the advantage of acting as construction barges for platforms that are commissioning production equipment. Their large rig-up crane, open decks where the DES is stored and transported, accommodations, and general facilities offer a relatively inexpensive construction platform compared with a construction derrick barge. Why would anyone want to use a TAD? They may be particularly attractive for standard platforms in water depths over jackup-rig rating and where space and/or load limits are a major factor, for deepwater spars and TLPs with the right number of wells, and for any platform where weight and space for long ERW are limited. Generally, a TAD costs more than a platform rig, especially the modular type, but they are a very attractive option for certain situations. http://petrowiki.org/PEH%3AOffshore_Drilling_Units#Tender_Assist_Drilling
