Canal Boat Cruising Supplies
What this covers
The on-board consumables and small-equipment kit you use cruising rather than building or maintaining the boat: fuels (coal, smokeless solid fuel, kindling, fire-lighters, diesel jerricans, propane bottles), lubricants (engine oil, gear oil, grease for the stern tube), water-tank treatment, toilet chemicals (for cassette toilets), washing-up and cleaning products safe for grey-water discharge, charts and waterway guides, windlasses, mooring pins, and basic safety/first-aid stock.
What to look for
- Solid fuel from a Smoke Control Area approved supplier if you intend to burn it in towns and cities — much of the canal network passes through SCAs and HETAS-approved smokeless fuels are required there.
- Bagged coal sold in 25kg or 50kg lots at canal-side fuel boats and marina shops; check it's a BSS-compatible bagged product, not loose run-of-mine.
- Toilet chemicals labelled as biological / formaldehyde-free if you use Elsan disposal points — Canal & River Trust and other authorities require non-formaldehyde products at most disposal points.
- Engine oil to the manufacturer's grade and specification (typically 15W-40 mineral or semi-synthetic for older indirect-injection diesels; check the engine handbook for modern engines).
- Fresh-water tank treatments rated for potable systems where you use the tank for drinking water.
- A working windlass that fits your local lock paddles (3/4" square or 1" square — most boats carry both).
- Red flags: formaldehyde toilet fluid sold at canal-side without warning about disposal restrictions, generic engine oil sold without spec, unbagged solid fuel without provenance.
Common questions
Where do I get diesel on the cut? Marina fuel berths and travelling fuel boats — the latter especially common on the wider network. Always check the declared split for propulsion vs. domestic when buying.
Can I burn ordinary house coal? Not in Smoke Control Areas, where you must use approved smokeless fuels. House coal also gums up boat stoves faster.
Do I need both blue and green toilet fluid? Modern bio-formulations work in most cassettes without separate odour and break-down products.
How much fuel do I burn per hour? A typical narrowboat at cruising rpm burns roughly 1–1.5 litres of diesel per hour. Higher with a thirsty engine or strong stream.
What's a windlass? The cranked handle used to wind lock paddle gear. Carry at least one of each size you'll meet — losing one mid-flight is a long walk.
When you need this
Stocking up at the start of a cruise, refuelling between marinas, replenishing the boat after a winter lay-up, restocking the bilge first-aid box, or buying that windlass to replace the one you dropped in the lock.
