It was the fourth anniversary of the sinking of the boat Jalakanyaka in Thekkady on Monday.
No official function was held in the tourist spot to pay homage to the 45 tourists who were killed in the tragedy.
The two-storey boat owned by the Kerala Tourism Development Corporation rests on the shore near the boat-landing station. The main reasons for the tragedy, which raised many questions on the safety of tourist boats, were the defects in the design of the vessel and overloading. As many as 95 people were on the boat with a passenger capacity of only 75.
The Crime Branch has said that its inquiry is complete and will submit its report before the court soon. A judicial inquiry commission has suggested measures for improving safety, such as provision of lifejackets to all travellers. However, these were implemented only for a short period and people seem to have forgotten them.
The tragedy affected tourism in Thekkady.
For over three months, boat services had not been offered in the spot.
The judicial commission of E. Moideenkunju, Sessions Judge, Alappuzha, inquired into the reasons for the tragedy and made recommendations to prevent similar incidents.
The commission submitted its report on August 25, 2011, to the Chief Minister. The report made 22 suggestions.
