Construction Of The 24-Foot Sailing Fishing Proa Coconut
The photos here tell the picture of the construction of our 24-foot sailing proa design Coconut in our boatshop in Honokaa, Hawaii.
She’s very similar to the 24-foot sailing fishing trimarans Tim built in the Marshall Islands in the 1980’s, except she’s relatively non-capsizeable when compared to the 24-foot trimarans, and probably faster under sail. These are VERY positive improvements for a small boat like this.
She’s 2,100 pounds at design waterline, that’s 1,000 pounds of boat, rig and gear, two 200-lb Micronesians, 400 lbs of fish, 200 lbs of ice, and 100 lbs of fishing gear. She’s 22 inches wide at her waterline amidships on a 22-foot waterline, for a 10:1 waterline fineness ratio. That means she should be fairly fast under sail, and easy to paddle when the wind quits.
Sophisticated and professional boat plans: (yeah right!)
Susanne and Sebastian (18 years) working on frames:
Jack (17) and Victor (23) setting up frames on the strongback:
Two of the bulkheads have 2 inches of blue foam glued to them, then ‘glassed with 3 layers 10 oz and epoxy, because they are the two ends of the insulated fish box.
Stringers and bottom planking on:
On 11-17-2018 we rolled her and installed the fiberglass chines on one side of the main hull; this is a view of the whole hull on her side (this makes putting the chines in easy):
View into the hull; the fiberglass chines are the bluish-green strips from left to right in the photo:
December 5, 2018; you can see the completed “pod” (except for its deck), and Susanne painting the inside of the hull. The long, skinny compartment just below where Susanne is working (that wasn’t there in previous photos) is the “sponson”. The sponson adds additional reserve bouyancy, additional deck area for walking and working safely, and will hopefully help make Coconut a drier boat by deflecting splash that comes up from the windward bow.
Also December 5, 2018; a little earlier in the day (before we flipped her on her side so Susanne could paint) another shot of the sponons when Susanne was “topcoating” it.
December 17, 2018; we’ve installed the decks in the “passenger cockpits” (those are the square holes with white inside them), more decking in the pod area, the insulation inside the fish hold, and the bow decking. Or is it the stern decking? This is a real question for a proa, because the bow becomes the stern, and vice-versa, depending on which direction you’re sailing at the time.
December 20, 2018; a shot taken with the iPhone’s “panoramic” photo feature; we couldn’t get far enough away from the boat in our small shop to take a normal photo.
Also December 20, 2018; a shot from the bow showing how skinny the hull is; this is why proas are such speed machines!
December 30, 2018; the last deck plank just went on, then we fiberglassed its top. You can also see the pod decking is on in this photo.
January 3, 2019; decking completed, deck fiberglassing completed, starting to sand the whole thing preparatory to painting. Sand, sand, sand!
Also January 3, 2019; Lucky and Rose on the proa for scale. Lucky is 6′-2″ tall, BTW! She’s a BIG little 24-foot boat!
January 10, 2019, Eucalyptus Saligna hatch coaming installed on the fish hold: 316 stainless steel screws, 3M 5200 bedding compound, and wooden plugs to seal the screw holes (plugs will be cut off flush and sanded, they will literally “disappear” in the wood grain of the hatch coaming wood). Saligna is a hard, heavy local wood with incredible durability, that we milled ourselves in our lumber mill.
January 11th, 2019, Susanne in one of the “fishing cockpits” installing deck hardware.
January 11th, 2019, later in the day, showing the whole deck with the hardware we just installed. That’s PB (shopcat) on one of the pointy ends. I mean, we can’t just call it “the bow” like we used to when I had a trimaran; there’s TWO of them, they’re identical. We’re really struggling with this whole “which end of the proa is it?” concept! We’re gonna have to come up with new words!
January 11th, 2019, closer detail of the deck hardware. You can see the big fish hold hatch with the long piano hinge in the center, white plastic access hatches and deck plates, Barient stainless steel #10 sheet winches on angled pedestals on both ends, little clamcleats for the jib furling lines, and Schaefer upright lead blocks for the jib furling line (the littel pulley thingie with the plastic tubing on it). The hole in the deck is for a hatch that isn’t here yet.
