Grandpa Glockman...Is it worth to buy this 500k yacht and move into it and use it like a home?

Then the sewer system and fresh water cost how much every month?
No idea. I know a friend who owned one party yacht. Still sold off eventually. As he could do welding & machining, he fixed up the toilet
Not sure about water but I vaguely remember he said about recycling system likely to use flushing. Drinking water should have water tank for refill.
 
The maintenance costs will kill you, even more expensive than owning a Ferrari LOL.
-------------------
Living full-time on a yacht (or large boat) in Singapore instead of in an HDB flat, condo or landed house may seem appealing, but the maintenance and recurring costs can add up. Here’s a breakdown of what you’d likely pay, based on public sources + reasonable estimates. Use this as a framework — actual costs depend heavily on yacht size, age, usage, and how upscale the marina is.

Key Cost Categories​


  1. Berthing / Marina / Slip Fees

  2. Utilities (electricity, water, sewage, etc.)

  3. Maintenance & Repairs (hull, mechanical, corrosion, etc.)

  4. Other Costs (insurance, membership, licensing, crew or help, etc.)

Singapore-Specific Costs & Examples​

Here are some real figures in Singapore to ground the estimates:

  • ONE°15 Marina (Sentosa Cove): a 50-60 feet yacht berthing cost is SGD ~$1,920-$2,300/month for Members. (one15marina.com)

  • Simpson Marine says berthing tends to cost SGD $480 to $1,500/month for smaller yachts, but for a larger (~60 ft) yacht the cost can exceed SGD $2,000/month. (simpsonmarine.com)

  • Utilities at ONE°15: electricity ~ SGD $0.58/kWh; water ~ SGD $8.80 per m³ for members. (sgmarineguide.com)

  • Marina Country Club: electricity ~ S$0.25 / kWh. (Marina Country Club)

  • According to MoneySmart, typical maintenance & repair + fuel for weekend-use boat/yacht might cost SGD $500-$1,500/month depending on usage. (MoneySmart)

What It Really Costs: Example Scenario​

Let’s assume a modest yacht (say ~50 ft) in a decent marina, used fairly often (weekends + some weekdays), live-aboard style. Estimate costs:
Cost ComponentEstimate (SGD)Notes / Variables
Berthing/Slip feeSGD 1,800-2,500/month (~SGD 21,600-30,000/year)For a 50–60 ft yacht at premium marina (ONE°15 etc.). If smaller yacht, cheaper; if larger, much more.
Electricity~ SGD 200-600/month (or more)Depends on how much shore power you use (AC, refrigeration, lighting, etc.). At ~0.58/kWh in ONE15, a big load (air-con, etc.) adds up.
Water & sewage / pump-out etc.SGD 50-200/monthDepending on water usage, shower, washdowns, blackwater pump-outs.
Fuel / propulsion (if motor yacht)Varies heavilyIf you move often. If mostly stationary, less. But engines still run for power, generator etc.
Hull maintenance & antifoulingSGD 5,000-15,000/yearNeed periodic cleaning, painting, treating with antifoul paints; combating marine growth etc.
Mechanical & engine maintenanceSGD 3,000-10,000/yearOil changes, filters, cooling systems, etc. More if larger engines or more usage.
Corrosion / seawater damageSGD 1,000-5,000+/yearSeawater is very corrosive especially on metal fittings, propellers, shafts, electrical contacts etc. Likely you’ll need periodic replacements, sacrificial anodes etc.
Interior upkeepSGD 1,000-5,000/yearCleaning, upholstery, wood finishing, mold/mildew etc especially in humid/tropical environment.
InsuranceSGD 1,000-several thousand/yearDepends on value of the yacht, usage, coverage. Probably 1-3% of value annually.
Licensing / membershipSGD 1,000-10,000/yearDepending on which yacht club, marina membership, import / customs / regulatory costs.
So, combining everything, for such a 50-ft yacht in Singapore that is fairly well used and more or less lived aboard, you might expect SGD 30,000-60,000/year or more in recurring costs beyond purchase cost. That’s ~ SGD 2,500 to SGD 5,000+/month, excluding the monthly installments you need to pay for the yatch if you are leasing.

⚠️ Things That Often Get Underestimated​


  • Corrosion from salt water wears things faster than on land: metal fittings, propellors, hull fittings, electrical wiring—all need extra attention and likely replacement more often.

  • Mildew, humidity & mold inside cabins. The tropical climate accelerates degradation of interiors.

  • Storm damage / weather: mooring damage, high wave damage, more wear in rough weather.

  • Labor / professional servicing: skilled marine mechanics / electricians cost premium.

  • Depreciation & resale: unlike property, boats depreciate, and resale costs (transport, shipping, brokerage) can eat value.

✅ Compare With Housing Costs​

To compare:

  • A modest 4-room HDB or small condo in Singapore might cost you SGD 2,500-4,000/month for mortgage / lease etc plus utilities etc.

  • A landed property will be much more, of course.
So while a ~$500K yacht might seem “cheaper” upfront, the ongoing costs far exceed what many pay for homes — especially in a fixed, well-constructed apartment where maintenance is shared or lower.
