Here I am
No longer living on a boat, but can still help.
Firstly, to store a boat anywhere you'll need a yacht club membership. The likes of One Degree 15 charge about $75,000, but you can probably get a transferred membership thru a membership broker for 15-20k. On the other hand, somewhere like RSYC will do a three-year "term" membership for about $4200. These are not transferable so you won't get it cheaper via a broker, but you might get a full membership for not a lot more via a broker.
Other options are Keppel Bay, Punggol and Raffles (Tuas). Unless you're connected to SAF (are you?)
Disclosure - I am a member of RSYC. I chose them as a compromise between location (closer than Punggol, Rafffles) and price (a lot cheaper than Keppel and One Degree).
TO help your decision, consider that the best boating in Singapore is around the Southern Islands - that is a long way from Raffles or Punggol. About 20+mins from RSYC depending on your boat speed.
Choosing a club and paying for membership is only one consideration - the second is berthing space.
There are pretty much no wet berths at Keppel & One Degree, both have long waiting lists. Possible at RSYC, I am not sure of the current status. More likely at Raffles and Punggol, as they are both less desirable for many in terms of distance.
However, if you're an occasional boater with a 25ft craft (odd size, more likely 22, 26 or 28ft!) then I would suggest you consider a Dry Berth. It's cheaper and kinder to your boat in the long run (don't need to anti-foul the boat if you're hosing it down after each run, less corrosion).
In which case, RSYC is probably your best bet. Not sure of prices, I would think around $10-$15 per foot per month. (A wet berth up to 35ft is $490 a month, and a dry berth will be a LOT cheaper).
With a dry berth at RSYC, you book up to 24hrs in advance and they will launch your boat for you via an over-size forklift. Less than 24 hrs and you might have to wait/queue for a launch. Six free launches per month, $20 for every extra launch after that. Weekends and public holidays are obviously busy.
On the return, they will place your boat on a washing rack and transfer it back to its storage rack when you're done. Plenty of crew around who will clean your boat for you for a few $$.
Now for costs...
Before you buy, you're going to need a license to drive a motorised boat in the port of Singapore. Its a theory course, exam and practical test for around $400. You can't drive a boat without it, and demonstrating knowledge of Maritime laws, custom and practice.
I would guess for a 25ft launch with twin outboards capable of 20kts, around 10-15yrs old and not a POS, you're not going to see much (if any) change out of $50k to $100k. Less than that you need to be suspicious. $50k might get you a crappy Chaparral with one engine, $100k might see you a Grady White with twin outboards. (Chaparrals are the Suzuki Swift of the boating world, Grady White more of a Volvo). Of course, you can spend literally $1,000,000 for a new 25ft powerboat with triple 300hp engines...
Even a Chaparral would probably get you to Batam or the JB marinas but immigration on your boat is a whole other ball game, for another post. Cheaper boats will only have one engine, and that might be fine if you are staying close to shore but otherwise...well you can imagine what happens if you lose that one engine!
Remember - everything costs more in Singapore - and boating is even MORE than that.
You're going to need to register the boat and licence it, get a Radio licence and pay insurance - that's about $3k right there, about $2k a year to maintain insurance/licence.
For a boat over 5yrs old, budget around 10% of the purchase price, per year, for maintenance and repairs.
Then add your fuel costs.
Being practical or mechanically minded doesn't help much either - the spare parts are a closed shop here. Gotta pay someone to do it, and even finding that person can be a nightmare, its such a small market in Singapore (unless you are a VLCC).
With membership, berthing, cleaning, paperwork etc I think you're looking at $12-$15k per year for something small and basic. That doesn't include the boat or fuel. Or the beers you'll need onboard.

There is a story told to anyone considering buying a boat as follows:
"If you're considering buying a boat, go to the bank and withdraw all your money in cash and put it in a suitcase. Go to the marina and throw the suitcase into the water and watch it drift away.
The next month, do it again.
And again, repeat for a year.
If at the end of the year you are still happy throwing all your money into the water, then you're ready to buy a boat!"
