"Fair prices" as it relates to the six letter word "marine" is a tough one, and I echo what webwench said about using the best. At least for the "essentials" like rigging
and structural components as it relates to ocean-going, you'd really be best served by going with the higher end stuff like Loos rigging
(as opposed to discount rigging made in China) and good quality marine plywood
for your bulkheads.
The nice thing about a small DIY boat is that the best stuff in the quantities you'll be looking for still isn't all that difficult to swallow. Find a local lumber
supplier who sells marine-grade. One nice sheet of 1/2 or 3/4 ply will be the most expensive piece of ply you've probably ever bought, but will go a long way on your boat and be well worth it not only structurally but also aesthetically. You want tight layers with good quality glue and no voids. Biaxal cloth/tape is an excellent tabbing material for bulkheads. It expensive and usually sold in large quantities ($600 or so for a 50yd roll I believe), but that should be all you would need for everything.
Having made the mistake in the past, I'd recommend taking on projects more or less one at a time and researching the hell out of each one before you get carried away with buying
supplies. At the same time, try to make sure you have everything you will need on hand for the project
And if you're re-doing your portlights
, if you've got factory right now I doubt those will be strong enough to take a punch from a breaking wave. You will probably want to replace.
Also make sure you invest in good quality thru hulls and sea cocks. If you're going simple and install a composting head
over the traditional marine
toilet, you should only need a few holes in your boat (one for raw water
for inboatd if applicable, one for sink drain, and maybe one for sea water
intake for sink).
Lots of high-end marine hardware
here, but some of the best: http://www.robinhoodmarinecenter.com/spartanmarine/
When you (re)bed any deck hardware
, cut holes larger than needed, fill with epoxy
to seal off balsa core
and then re-drill to size. Countersinking the final holes slightly is a good idea to give whatever sealant
you use a nice O-ring type seal that has plenty of room to flex. I been using marine-grade butyl tape recently for bedding compound and love it. Need Butyl Tape ?? Photo Gallery by Compass Marine at pbase.com
