Canvas / Canvas Maintenance Items
Canvas Synthetic Fibre Tarpaulin
Canvas Synthetic Fibre Tarpaulin is a group of 24 IMPA-coded items (codes 232221–232257) under Canvas / Canvas Maintenance Items in the Rigging Equipment & General Deck Items section (IMPA 23). All of them are priced per metre. The names most often specify polyester (10 of 24). The list runs through 16 metric sizes from 0.35 mm to 0.88 mm.
Buying guide
This group is coated synthetic tarpaulin cloth sold by the metre — polyester, vinylon and nylon in several thicknesses and widths. It is light but strong, resists sea water and sunlight, and is made up into covers, awnings, tents and similar. The standard bolt is 50 m or random length.[1]
The bosun raises it when covers wear through; on ships with tarpaulin-secured hatchways it is also the material of the hatch tarpaulins themselves.[2]
How to specify it
State the base fibre (polyester, vinylon or nylon), the thickness in mm, the width in mm, the colour and the total length. The catalogue items differ only by these values — for example polyester from 0.47 mm to 0.82 mm thick and widths from about 920 mm to 1,850 mm — so a quote that drops the thickness is not comparable.
Sewn seams need sealing: the catalogue notes that needle holes must be sealed with a waterproof agent or modified polythene resin. Order the sealant with the cloth if covers will be made up on board.[1]
Rules and certificates
Load Line regulation 15(11): at least two layers of tarpaulin in good condition shall be provided for each hatchway in position 1 or 2 closed by portable covers. The tarpaulins shall be waterproof and of ample strength, of a material of at least an approved standard weight and quality. Battens and wedges must be efficient and in good condition, and steel bars or equivalent must secure each section of cover after the tarpaulins are battened down.[2]
COSWP asks for enough properly fitting tarpaulins, batten bars, side wedges and locking bars for wooden hatch covers so the hatch stays secure and weathertight in all weather, and for crew handling tarpaulins to walk forwards, not backwards, so they can see where they are going.[3]
Questions buyers ask
- Can this cloth be used for hatch tarpaulins?
- For hatchways in position 1 or 2 the Load Line rule asks for at least two waterproof layers of a material of an approved standard weight and quality. Check with the flag or class what weight is accepted before making hatch tarpaulins from it.
- Polyester, vinylon or nylon — which should I order?
- Match what the existing covers are made of so repairs and seams behave the same. The catalogue lists all three in several thicknesses; state the one you need with its width.
