3 Terms
According to GB 8242.4 and CB 11573 Chapter 1 Regulations 4 Technical Requirements
4.1 Partially enclosed lifeboats shall be made of a rigid hull made of flame-retardant glass steel and a permanently attached rigid roof of not less than 20 cm in length at the bow and stern.
4.2 The strength, stability, performance, crew quota, passage, buoyancy, propulsion equipment, accessories and equipment of partially enclosed lifeboats shall comply with 4.2, 4.3.2.1.4.1.5, 1.6.4.7, 4.8 + 4.9 of H11573 respectively. 4.3 Partially enclosed lifeboats shall be equipped with a permanently attached foldable roof. The foldable roof together with the rigid roof forms a windproof and rainproof body, completely covering the lifeboat occupants and protecting them from wind and rain. The foldable arrangement shall be: with suitable rigid profiles or strips to enable the awning to be raised: h. It can be composed of no more than 2 The canopy can be easily propped up by one person. The canopy basket should be insulated with less than two layers of material separated by air gaps to protect the occupants from the damage of cold and heat, and facilities should be provided to prevent the accumulation of particles in the air space. The outside of the canopy should be a bright and visible clear yellow. The color of the inside of the canopy should not make the occupants feel uncomfortable. c. There should be inlets at both ends and both sides of the canopy. The inlets should be equipped with effective adjustable closing devices that can be easily opened and closed from both inside and outside, that is, air-permeable (meaning to prevent the intrusion of seawater, wind and cold air, and facilities should be provided to semi-fix the opening and closing devices at the inlet.

f. After the inlet is closed, there should be enough air for the passengers to enter the pre-inlet. The equipment for collecting the air should be installed:
h. If the boat is tilted and the passengers cannot escape, 4.4 Each partially closed lifesaving chamber should be equipped with effective water trapping facilities or automatic water-removing facilities. 4.5 The height from the upper surface of the floor to the top of the boat in at least 50% of the floor area is not less than 1.7m. 4.6 The allowable deviation of the station of partially closed lifeboats should comply with the provisions of 4.1.3 of GB11573. 5 Test methods
5.1 Strength test methods shall comply with the provisions of 5.1 of GB11573, 5.2 Material test methods shall comply with the provisions of 5.2 of GB11573. 5.3 Stability test and dry limb determination methods shall comply with the provisions of 5.3 of GB11573. 5.4 Seat test methods shall comply with GB 5.1 of GB 11573, 5.5 Interpretation of the mechanism test method shall be in accordance with 5.5 of GB 11573. 5.6 Operation test method shall be in accordance with 5.6 of GB11573. 5.7 Water test method shall be in accordance with 3.7 of GB 11573. 5.8 Tightening test method: The boat is fully occupied and two crew members shall hold the folding seam upright to verify that the operation is not obstructed and can be completed within 2 seconds.
