A charter yacht or a ferry that turns around between shifts gives the cleaning crew a narrow window and no second chance. On a yacht exterior the surfaces are also expensive and varied: gelcoat, antifouling hull paint, stainless and chrome fittings, teak, synthetic deck decking, anodised aluminium, glass, rubber seals and a stack of through-deck fittings that must not be forced. A service provider working in that environment needs records that protect both the client and the crew: proof of what was done, evidence of the condition found, and a method nobody improvises on a wet morning. The documentation structure below is what a marina services manager or an on-board cleaning contractor should be producing.
1. A pre-clean condition survey with photographs
Before a wand is lifted, walk the vessel and record the condition. Photograph, with a date stamp and a consistent sequence, the areas where disputes start: gelcoat with crazing or chalky oxidation, existing cracks at chain-locker edges, lifted antifouling, blistered paint around through-hulls, scratched stainless, clouded windows, and any repair or touch-up already present.
Record it as a signed sheet the skipper or mate countersigns. That single page resolves 90 percent of claims about work done in a hurry, and it also tells the crew which areas the method must avoid.
2. A per-surface method statement, not one general instruction
Write the method for each material, because the materials behave differently under heat and pressure:
- Gelcoat and topsides: no stationary jet, no close-range pressure, working from clean areas toward dirty.
- Hull below the waterline: antifouling condition dictates what is allowed; a soft or peeling coating rules out aggressive work.
- Stainless, chrome and anodised trim: specified pad grade and product only; no acidic cleaner left to dry on the surface.
- Teak: no high-pressure jet along the grain; the method is defined and consistent, because over-scouring removes timber permanently.
- Synthetic decking: cleaner choice and dwell stated, plus the rinsing requirement, since residue on decking is a slip issue.
- Windows, seals and through-deck fittings: distance limits, dwell limits, and a written rule about seals and any fitting that can be driven open.
3. Record the equipment and its settings
On a between-shifts job, the settings actually used matter more than the machine name. Log the equipment identity, the mode, the temperature and pressure in use, the nozzle and standoff distance, and which operator ran it. Heat-based cleaning reduces how much chemical the job needs, which is a real advantage close to sensitive surfaces: equipment offering a dry-steam and wet-steam choice lets the crew use a low-water pass on topsides and a heavier pass on the waterline and stern, and the mode used is a line item in the record rather than a matter of opinion afterwards.
Published figures give the record something to reference. The fixed model in this class is specified at 160°C steam temperature and 0.8 MPa vapor pressure on a 220 V supply, so a client can see exactly what energy was applied to their gelcoat rather than being told the crew "used the steam machine".
4. Time, labour and handover records
For each shift, record crew names and hours, start and finish, and the sections completed against the work order. Between-shifts work is often interrupted by a departure; a handover note that states what is done, what remains and what was deliberately left for the next window is what prevents a half-finished job being read as a finished one.
5. Chemical inventory and storage on board
List every product taken aboard with its name, dilution, safety data sheet reference and where it was stored while the crew worked. Marinas and operators police this tightly, and a product used without a record becomes a compliance argument after the fact. Where heat replaces detergent, the inventory gets shorter — which is worth stating plainly on the record, because fewer chemicals aboard simplifies the operator's own paperwork.
6. Runoff, containment and where the water went
Wash water from a hull and topsides carries antifouling residue, oils and whatever product was used. Document the containment arrangement and the disposal route for the shift: what was captured, where it went, and who collected it. In many marina environments this is a hard rule, and in any case low-volume methods make compliance realistic — a machine that heats a bounded tank of water, such as the 80 L unit referenced on the fixed machine specification, produces far less runoff than an open hose, which is why it is often the only method a pontoon or hardstanding can legally support.
7. Power, water and the utilities actually used
Record the supply used — pedestal, shore power, on-board generator — the outlet, and the cable route, together with any restriction the marina imposed. Note also the water point and the fitting type. On a busy pontoon these details decide whether the job happens in the window, and the record explains a delay without argument. Battery or mobile equipment changes that story completely, and the range of mobile cleaning machines exists for sites where the shore supply or the layout cannot be relied on.
8. Post-clean condition and the exceptions list
Photograph the same sequence after the clean, and finish with an exceptions list: anything found during work that was not in the pre-clean survey, anything deliberately not cleaned, and anything that needs the owner's attention. A client who receives before-and-after photographs in matched positions plus an exceptions note renews a service contract without being chased.
Keep it to a form the crew will actually fill in
Documentation that takes twenty minutes a shift will not survive a wet evening. Build it as a one-page form with tick boxes, a photograph sequence reference, and three written fields: exceptions, handover, and containment confirmed. Then the record exists, the crew complete it, and the provider can show a surveyor exactly what was done and to what standard. Where a vessel's surfaces or a marina's constraints fall outside standard practice, that same record is the basis for requesting a configuration matched to the job — customised cleaning solutions are specified from documented site conditions rather than from a guess.
