In my perfect world, it actually would be a dive compressor that could fill a tank, and also have high cfm to drive a tool or two.

I actually found the ideal dive compressor, diesel, 10.3 CFM erc...
The downside is that it was relatively huge, and 15 grand.

Re: Need Some Compressor Advice from the Full-of-Hot-Air Blowhards ;-)

Hi cruisers, I'm a boilermaker with 15 years experience and a steel yacht.I would like to put my 5 cents worth in.
I have a 8.5 cfm compressor with a 20 Gal tank and wouldnt try to run a needle scaler with any thing less. 2.5 hp, one of the biggest that will run on 10 amp power. Electric grinders for me, air grinders bog down under load. I have a 1000 watt 5" gringer to use on shore power and a 500 watt 5" grinder that I keep on board because it will run off the 1kva generator without tripping the power. I keep a small 150 amp inverter welder on board to use with shore power. I take all my "jobbing" away from the boat. It's so hard to clean up all the grinding dust and the little rust spots are almost impossible to stop. While away the 5" grinder with a flat wire wheel will substitute for the compressor and needle scaler. The tool I bought for the yacht after the compressor and needle scaler was a wet and dry vacuum cleaner from the hardware store for cleaning up.

I do all my own steel yacht maintenance , use a range of air tools including a needle gun and small hand held grit blaster. Would not consider less than about 15 cu ft free air delivered compressor, and even then have an extra air reciever teed into the compressor line to give more capacity.
Regards,Richard.

Hey, thanks for this! those look pretty good.

Re: Need Some Compressor Advice from the Full-of-Hot-Air Blowhards ;-)

I have a 12KW gen set so I plan to go electric everything. Including scuba compressor
After I splash her, I'll carry a small lincon wire feed welder and the other basic metal working tools. I'll leave the mig, the buzz box and CNC in the garage. I really plan to NOT work as much as possible once the keel is wet. (pipe dream , I know)
Now let me explain that I am a dumbass.
I put a wooden deck and wheel house on a steel boat, so i will carry another set of tools to maintain the the wooden parts too. Tim "the tool man" Taylor would be proud of my tool locker.....LOL

Re: Need Some Compressor Advice from the Full-of-Hot-Air Blowhards ;-)

Xymotic,
Our compressor kind of evolved. It started off as an electric 6.5 FAD unit. Then I wanted to take it out to the mooring, so I ditched the electric motor and replaced it with a used Honda petrol motor.
Soon found that 6.5 FAD was not enough air to blast well with 1/4 inch nozzle so took the compressor head off and fitted a larger unit.
Still not satisfied, I teed an old 100 lb gas cylinder (well purged and drained) into the line for some extra capacity. Ten years later, it is all working well.
Lift it on and off the boat using the boom and topping lift as a derrick.
Regards,
Richard.
