Okay, I was thinking about the boards to lock the cabin. I want to use something less exspensive than teak. If I got to replace it in 3 years instead of five... who cares.
Doesn't make a huge difference what you use as long as it keeps the rain (and thieves - if that's an issue) out. You can use regular plywood if you seal it really well and plan on replacing it every couple of years. Marine Plywood would be better, Lexan would be really great (might cost money though).
I'll have prolly sold the boat by then. It has no railing around the sides (can't tell if it's called stanchions or lifelines or both) But 1 aluminum pole is about $130 less than SS.
On a 22 foot boat they are more decoration than safety feature. I wouldn't worry about them right now - later - if you keep the boat - get stainless steel.
Electrical, I am thinking about just using car audio wire from walmart and replacing the incandescent bulbs with a 4 cluster of LED bulbs.
Might be better to go with house wire. The audio wire is not heavy enough to handle what the battery MIGHT put out if it shorts - it is possible for your battery to start a fire.
I was thinking of using brass hinges or trying to find some from SS at homedepot for $% instead of $35 at west marine, to fix the seats and port cover.
Good idea - West Marine is expensive and there is no need to waste money - just don't use regualr steel because it is really difficult to get rust stains out of fibreglass.
I replaced the swing keel line with 3/16 steel cable from lowes and a $3 SS shackle from lowe's too. I figure, the replacement costs $8, so what if I gotta drop $8 and 20 minutes every 6 months or so versus buying some special marine grade stuff from west marine for 5 times that every 6 years.
Make sure you check that cable religiously - like every time you take the boat out of the water. It is a fairly important piece.
You are not doing anything that a lot of other folks haven't done. My one suggestion would be to remember that, if you intend to sell the boat in the forseeable future, you shouldn't do anything "permanent" to it that cannot be easily fixed or upgraded by someone buying it from you.
Hope the project goes well and that you have many great sails in her !
