Re: 1989 Hunter 40 - A million questions.

you may not need to winterize but need to consider what happens when it is stored in a wet warm climate. there are some books on the subject. i have read a few many years ago. We don't do either with our boat we sail year round. In Florida things will grow in and on everything

No winterizing. The boat will be near Ft. Myers.

What do I do about the electrical system? We have solar, so do I just leave it all "running" as usual to keep the batteries charged? Should I leave a couple of lights on inside to provide some draw?

Thanks for the tips.
Will you need to winterize? If you can, it might be a good time to scrub the water tanks and completely dry them. Winterizing might be a good way to keep mold and scum from growing in the lines.

The holding tank... pump out and fill with fresh water, pump out and fill with fresh water, again and again until all the sediment is gone...or else you are making cement on the bottom. Maybe a gallon or two of antifreeze is the way to go even if it won't freeze, just to keep things liquid.

I would take out the batteries and store on a trickle charge, remove the solar panels and store. 10 months is a long time to sit in the sun, wind and rain.

Leaving electrical stuff running for 10 months unattended does not seem like such a good idea, but I'm not the expert....beatlejuice, beatljuice, mainesail.

This is true if they are the rolled sheet crush washers. that are like an ring made of tubing. they should be only used once. the soild copper sealing ring can be reused if they are annealed

Re: 1989 Hunter 40 - A million questions.

Barque 'Washer starts out soft,Work hardens . Like new wire, bending breaks up big soft 'Crystals' of metal ,more smaller 'cells' of soft left,more boundaries to fracture. gets hard,leaks or fails. Bring copper to annealing temp and atoms regroup and form large crystalline structure (soft,malleable) Ferrous metals workharden and fracture too .Bring to red hot and cooling slow anneals. Cooling quick traps the carbon and other additives in the matrix and make brittle ,hard .reheating a bit and quenching allows control of how much (Think knife, spring , file ) Same with aluminium .Extruded is usually a copper alloy Heating to where the carbon soot from the smoky torch burns off allows the copper atoms to redesolve into the Al. Take care as it melts with only a bit more heat Got maybe few hours of malleability before the copper re forms little alloy crystals and softness is gone (think aircraft rivets ,,annealed ,kept refrigerated until used.) No numbers offered here, just a mental exercise what;s what at an atomic level.

Re: 1989 Hunter 40 - A million questions.

Capt - I am not enough of a metallurgist (or any other 'urgist, for that matter) to know what annealing does. Is that to harden the otherwise soft washer?
