"Nilai ekonomi ikan kerapu bebek dan ikan kerapu tikus yang begitu tinggi hingga mencapai ratusan ribu per kilogramnya membuat banyak orang tertarik untuk membudidayakannya. Sehingga tuntutan akan alat angkut yang cocok pun kini menjadi perhatian. Penulis mencoba memperkenalkan alat angkut berjenis kapal trimaran dengan lambung tengah sebagai kolam ikan dan lambung samping sebagai propulsinya. Dengan bantuan software hydromax pro versi 11.12, penulis mencoba menganalisis stabilitasnya. Pada 3 kondisi pemuatan serta variasi jarak antar lambungnya menghasilkan nilai periode roling kapal yang cukup lama yakni 18 - 27 detik, untuk stabilitas memanjang kapal ini trim ke depan sedangkan untuk stabilitas melintangnya, kapal hanya mempunyai sudut oleng maksimum sebesar 90 agar propeler tetap tercelup air.

The economic value of grouper fish which is very high, up to hundreds rupiahs per kilogram make people interested to cultivate it. There for, the needed of a type of trimaran ship with middle hull as fish hold and sided hulls for propulsion system as distribution tools or transportation. Analyzing of the stability is using hydromax pro v. 11. 12. In three loading condition and length variation, the rolling periode of trimaran is long enough, between 18 - 27 s. But, the longitudinal stability is front trim, and transverse stability, maximum angle is 90 to make the propeller still drowning."

"High speed catamaran and multihull high speed marine vessel have become very popular in the last two decades. The catamaran has become the vessel of choice for the majority of high speed ferry operators worldwide. There have been significant advances in structural materials, and structural design has been combined with higher power density and fuel efficient engines to deliver ferries of increasing size. The multihull has proven itself to be a suitable configuration for active power projection across oceans as well as for coastal patrol and protection, operating at high speedd for insertion or retrieval with a low energy capability. At present there is no easily accessible material covering the combination of hydrodynamics, aerodynamics, and design issues including structures, powering and propulsion for these vehicles. Coverage in High Speed Catamarans and Multihulls includes an introduction to the history, evolution, and development of catamarans, followed by a theoretical calculation of wave resistance in shallow and deep water, as well as the drag components of the multihull. A discussion of vessel concept design describing design characteristics, empirical regression for determination of principal dimensions in preliminary design, general arrangement, and methods is also included. The book concludes with a discussion of experimental future vehicles currently in development including the small waterplane twin hull vessels, wave piercing catamarans, planing catamarans, tunnel planing catamarans and other multihull vessels."
