This paper describes a discusion on a SES concept without flexible seals. A weak point of Surface Effect Ships(SES)is considered that they have flexible seals which require both labourous maintenance treatments and high maintenance costs, Recently, a new concept of the SES without flexible seals has been reported. Its hull form consists of the twin frontal hulls and the hull with aircushions, which could eliminate the frontal and the aft flexible skirts of the usual SES. The calm water resistance was calculated and examined for this type of the hull without flexible seals. And it was compared with the resistances of the hulls with flexible seals and the usual displacement catamarans. It is found that the value of resistance of the SES without seals is about 60% of that of the usual displacement type catamarans although it is slightly higher than the SESs with flexible seals at the speed of 40〜50 knots. The results are promising the application of the hulls without flexible seals for fast carferries.
