What do you find useful for working on ya boat on the water? When I have had access to a pontoon wharf with power and water, it was soo much easier to get jobs done. I found doing repairs with Windchaser on a buoy mooring quite a challenge. After an initial surge of energy and doing weeks of internal sanding and fairing by hand, I gave up and bought a small 4 stroke generator.
I selected a 4 stroke .7 kva Kipor for about $400 as it runs most of what I need, is very light, and relatively quiet. The tools I use most are an orbital sander, drill with various attachments and grinder.
I start the orbital sander and drill on low speed then speed them up, the overload light on the generator does not flick on. The drill is rated at 1000 watts so theoretically is too large for the 770 watts maximum of the generator however, I do not use the drill on the hammer setting and start it at low speed so it does not draw anywhere near what it could. However, the 500 watt grinder kicking in does cause the generator's overload light to momentarily glow so it is not something I turn on and off all the time.
While I still do lots of hand sanding and use other manual tools, the small generator and power tools mean I get a lot more work done in the short times I have available on the boat.
What do you use that helps to get those repairs done?
