My Next Dinghy Project - Construction
You can never have (or build) too many small boats :-). 
Here is the planning for this project.
 
Spring Hill, 7 Jan 2012
I decided on building the Spindrift 10N. 
 Here are the costs (so far) ...
ItemCostShip- pingSourceNotes
Plans $65 $5 B&B Yacht Designs The plans consisted of 13 A3 (11½" x 16½") sheets of drawings and instructions, and 25 8½" x 11" pages of material list, sources, their prices for materials and hardware, etc.  The plans include pretty good detail on the sail rig.  The materials list includes a couple alternative manufacturers (Ronstan, Racelite and Harken) with model numbers for all the sailing hardware.  There is a helpful list of recommended sources for the plywood, aluminum tubing for the mast and other materials.  There is a CD included with about 250 photos of Spindrifts under construction and finished.  All in all, it looks like a pretty good set of plans.
Plywood 4 @ $68.80 = $275 $10 World Panel Products I placed an order with World Panel Products for 6mm Okoumé.  WPP calls it simply "Okoume Marine BS1088 Plywood".  What they're currently offering is made by Garnica.  It is 100% Okoumé - that is, all the plys are Okoumé.  Their 6mm plywood is 5-ply, each ply ~1mm (with the face plys a little thinner than the core plys).  I believe it is Garnica's Okouply Premium but haven't been able to confirm that.  The World Panel Products warehouse is just a couple blocks from the port at West Palm Beach so it will be easy to get the plywood to the shipper.  WPP has been nice to work with, and is packing the plywood on pallets for "export shipping" plus transporting it to the shipper for a nominal $10.
BTW, B&B is offering 6mm Joubert "Okume marine plywood BS1088" at a simiar price ($75 as I write this) but the price sheet says they "do not ship plywood - pickup only".
Fiberglass & resin $479 $50 boatstore .com I chose to use West System epoxy and cloth.  boatstore.com had the best prices I could find.  Note that this line item includes 3 yds of 6oz cloth that I plan to use on the bottom.  That added $45 to the cost not in the original plans from B&B.
Hardware for the sailing rig $133 $16 B&B Yacht Designs Except for one or two items, B&B had the best prices (and generally much lower than I could find elsewhere) for the hardware for the sail rig.  Curiously, the 2 Harken micro blocks were of an old design (and didn't match), but at $6.50 each I guess I can't complain.. well, too much.  I'll pick up a couple new ones at West Marine next week.
Misc hardware $21

Auto-release Clamcleat CL257. B&B had been out of these.
Sheeve for the top of the mast.
Line $69 $10 P2 Marine The line for the sail rig.  40' x 5/16" and 100' x 3/16" of NER Sta-Set in various colors.  This order also included a Harken 4mm bow shackle.
Sail $340 $22 B&B Yacht Designs I got the sail with a zippered luff and 1 reef point.  Included were the insignia and sail #, and a sailbag.  It looks to be well made.
BTW, the sail from Sailrite with a sailbag was $234 for the kit + $275 labor.
Clamps for joining the halves 2 @ $48 = $96 $4 discount marine supplies .com These were expensive, but I expect they will be very convenient.  Garry Prater, who came up with this idea, described to me how he was able to join the two halves in the water and how he did that once in gale-force winds in an emergency - when he had to launch his dinghy to carry out an anchor in the Intracoastal Waterway during a sudden storm.  (Times like that make for *very* vivid memories :-)
Watertight access ports $xx $xx Probably BOW These will be for access to the floatation compartments.
Stainless steel $15(mat)
$75(fab)
$13
 
Online Metals I ordered 3' of ⅛" x 1½" Stainless Steel Flat Bar T-316/316L for the mast plate and the brackets to join the two halves.  I'll have a local fabricator drill and countersink the holes and make the bends.
Oarlocks & sockets 2 sets @ $20 + $30 = $70 $5
(tax)
West Marine I like these sockets because they have replaceable nylon sleeves and are nice and quiet.  I'll probably install 2 sets of sockets to have a 2nd rowing position - where I can sit at the bow to balance the boat when need-be or for occasions when I want to row for a while facing forward.
Mast $154 $19 Online Metals I went with the 6061-T6 from Online Metals.  Spindrift's large plan sheet calls for 2" aluminum at the base while the materials list calls for 2¼".  I called the designer, Graham Byrnes, and told him that I liked to go out in "fresh" conditions and asked whether the larger diameter mast would be better.  He said the mast size has evolved a bit and that yes, I should not have any problems (like permanently bending the mast in strong wind) with the larger diameter.  They had found the larger diameter mast bent less in normal conditions, maintaining better sail shape and sailing faster.  That was the reason for the change from the original plans.  He said he has sailed the Spindrift in over 500 races.
Shipping & customs - about $770 Abaco Shipping, Arawak Agency (Customs Brokers)
Based on materials cost of about $1000
Customs Duty 410
Freight 220
Brokerage 139
This is an initial estimate of the cost for shipping from West Palm Beach to Marsh Harbour.  It was based on my rough estimate of $1000 for the plywood, resin, and fiberglass cloth.  To the right is a breakdown of the costs.

 Start of construction
Spring Hill, 17 Jan 2012
So I guess this is the actual start of construction.  Woo-hoo!
 
I received 3' of ⅛" x 1½" T-316/316L stainless steel today and brought it over to the fabricator.  This is for the plate at the base of the mast and the connectors for joining the two halves.  Garry Prater's plan called for 2 connectors, but I think I'll add a 3rd in the middle as I've shown here.  For the two bolts on the left of this plate (that will overlap the trunk, shown in blue), I'll use the West System technique of drilling the holes oversize, filling them with epoxy, and embedding the bolt's threads into that epoxy plug.  I believe the West  
System guys have determined this produces a connection stronger than the wood itself.  Actually, I think I'll do that for all the bolts (rather than a nut and washer on the inside) - to reduce the number of toe-stubbers inside the dinghy.

And the results.  Hey, it's a start.
Now I need to get back to Man-O-War to start on the hull.


Misc notes:
  For the Spindrift, a good idea for joining the two halves.
I like these flush mounted hatches and installing them without toggles although commercial screw-in waterproof deck plates would probably be more practical.
