On a sailboat those kinds of speeds feel quite incredibly fast.
Is a trimaran faster than a catamaran. The trimaran NEEL is faster than catamaran. The trimaran has the widest range of interactions of wave systems generated by hulls at speed. Doing 20 on a sailboat feels like doing 40 in a powerboat possibly even more exhilarating than that.
This is also true for cruising trimarans as proven by the last ARC rally won by a NEEL 47. Try GOLD FREE for 90 Days. They are faster safer and more comfortable than anything with a single hull.
Trimaran and catamaran sailboats are typically much faster. An offshore catamaran or trimaran. Due to their lighter weight multihulls tend to be faster and can sail better in lighter winds.
While a catamaran is still faster than a monohull of identical size it falls short of the trimaran in terms of sheer speed. Trimarans with one or two daggerboards or a centerboardusually have a better ability to tack and to go to windward and aregenerally faster for the same length of boat. As a result trimarans are generally more.
Gone are the days. The superiority of the trimaran is obvious during upwind sailing especially due to the rig. Then are trimarans faster than catamarans.
Monohull skiffs are some of the fastest boats around. Trimarans are therefore faster than catamarans and this difference is very significant when sailing into the wind thanks to the centering of the weight in the central hull which limits pitching. But like all things it depends on conditions size and so forth.
