The Harvester Project - 31' Mega Panga

After the empowering experience of The Discoverer Project, the FishingNosara Build Team has set on yet another course to redefine Costa Rica sportfishing.

The genesis of The Harvester Project was in the success of our 26-foot Super Panga Explorer.



The combination of a big-bow panga hull with a single Yamaha motor has proven unbeatable for fishing in our stretch of ocean.

As her legend grew, we began to wonder what the Explorerwould be like if it was just as big as the Wanderer and Discoverer.

We searched far and wide for the best panga hull manufacturer in the Western Hemisphere and, after a few mis-steps and dead ends we found the clear choice: Eduardono Boats based in Columbia.

The 32-foot Corvina hull is exactly what we are looking for: strong, light, and proven to last in rough conditions.



Like all panga hulls she is big-nosed, narrow in the waist, and flat on the bottom; these factors make it so that a single motor can get this boat up on plane and therefore saves a ton of fuel.



We placed our order with Eduardo a few months ago, and Craig got to work sketching out his dreams for the ultimate 'Mega Panga".





As the days crawled by we were left to salivate over this single picture:



Finally on November 3, 2014 she arrived to her new home in our Jacksonville, FL shops. Getting it out of the container was a little dicey:









Once settled we got her out of the box and hanging on chain hoists, we had to construct a cradle so the boat would sit level on the ground.

We won't be getting a trailer for this boat until later in the project, so it is critical that our saddle be at perfect level so that when we start laying out the floor and consoles things don't get off-square.













It took most of a day, but the Harvester is settled, level, and ready for us to sink our teeth into this meaty project.







The Harvester Project is officially underway and we are stoked to bring you regular updates live-as-it-happens on the Florida Sportsman Boat Build Forum.
Pura vida!

    Looking good Matt, were those technical drawings done in AutoCAD or Shipwright software? :grin

    Looking forward to another one of your builds.

    Wish I knew! Eduardono provided these drawings, and of course Craig's magic #2 pencil provided the rest :)

    Did you buy the hull from them "new" like that?

    That's right.

    Now Eduardono usually sells these boats 'finished' with the floor installed, several console options, etc., but we asked for it bare to make our work easier. If you look back at our other boat renovations, a lot of time and effort was spent to sand off old gelcoat, cut away old floor sections, and generally prep for new fiberglass.

    With this boat, the outside of the hull is finished and the inside is bare fiberglass so we are essentially ready to build. I'll post again later today with pics of the consoles and a new bulkhead that are almost ready to install.
    Pura vida!

    And here I am working on my 14 Ft. Panga and learning along the way. Kind of interesting the interior bulk head construction of my little boat and your mega boat are very similar. Of course you guys would get a chuckle out of my work. Looking forward to seeing the boat take shape.

    Trust me bro...all boats are tough! I like to poke around this forum and look at 60-80 ft. boat builds and am shocked at how weak our builds are in comparison.

    Still it all boils down to good prep work, fastidious cleaning, and patient application of resins/paints no matter how big or small your boat. The fundamentals are the same.

    Yes we probably could have, but we can't afford the extra labor. Also there would be an intermediate step of visiting a marina with a big forklift to take the boat out of the container and onto a flatbed. Plus we like to improvise! :crossed

    We're already catching a groove here on The Harvester Project.



    Craig, Brian, Alejandro, and I wasted no time to lay out the positions of the consoles, seats, and coolers. We also referenced the diagrams from Eduardono to determine the midpoint and weight bias so that the ice-filled coolers and gas tanks don't weigh down the back end of the boat.



    We are going to build a small cabin with a toilet in the nose of the boat, so the first major piece we've built is this cabin bulkhead:



    We use Coosa 26lb. Bluewater 'wood' for this piece, 3/4 inch thick. Coosa wood is really cool stuff; lighter and stronger than wood, easy to sand/shape, and fiberglass matte grabs onto it like Velcro.

    The drawback? $300+ per sheet :banghead

    So for this complicated piece we first fabricated it out of cheap press-board, then transferred the pattern over to the expensive Coosa wood.



    Despite the high cost, we are going to use Coosa exclusively throughout the boat for all the major construction, including the floor. We are going to try and get away with only one motor so weight will be a big factor in the HP decision. Also, in Costa Rica the gasoline costs $8 a gallon so fuel efficiency will also be a huge concern.

    We may break the bank buying Coosa now, but it will pay for itself in fuel savings over time.

    Here are our consoles, also made out of Coosa:







    We want split consoles (like our other panga the Explorer) because the long walkway down the center is a big boost for client comfort.









    On virtually all production boats the consoles (center or split) affix to the top of the floor. On the Explorer we found that consoles created a lot of flex in the sides of the hull.

    We saw the telltale cracks around the floor after the first season of fishing and had to add a piece of holding wood to tie the consoles to the side of the hull.









    That repair was a real pain-in-the-ear so we are taking this opportunity to build the consoles into the boat all the way to the stringers.

    Check out this force-sharing arrangement between the stringers and the consoles:









    Once we glass these bad boys into place they will literally become part of the hull.

    We'll be moving on to the rear coolers and tackle boxes next week, and until then keep the comments coming...we're happy to hear your opinions and will welcome any advice.
    Pura vida!

    Awesome,

    You didn't consider a center console?

    Are you going to cover those ribs or leave them exposed? What about a floor?

    We will build a floor at the height recommended by the hull manufacturer. Here is the floor of our current panga boat the Explorer and you can see how some portion of the ribs are under the floor and then the top end are exposed:

    We thought about it, however we really like the sight-lines created by a split console. At FishingNosara we are junkies for good photos and videos of fishing action, and we feel that on a narrow beam boat without a tower it is virtually impossible to get good shots.

    Check out this short clip of highlights from the Explorer to see the advantageous sight-lines:

    Nice Matt, I didn't realize that a panga would back down that well. Looking forward toward seeing this one come together.

    I see looks good, they look huge now but when the floor goes in I bet it will be fine, keep the pics coming.

    Matt,

    I fished three days on the Wanderer with Capt. William and Alex last year. Had GREAT trips.. The bigger boat was great, and we had some great weather so mid day trolling got pretty warm in the shade around the helm, even with the front windows open. Looks like this new boat will have plenty of space, and I'm guessing be more comfortable on those warm days.... This new Panga will be great for the type of fishing you guys do..

    The construction rolls on as the team struggles to lay up a lot of fiberglass in the face of gusty winds and low temperatures.



    We have been patient in waiting on the thermometer to climb north of 50 degrees before working, and are using 2% catalyzer to make sure this glass kicks off properly.























    Meanwhile, Brian has completed both of the large cockpit boxes; these installations will function as seats, coolers, and leaning post/fighting chairs. Like the consoles they are designed to attached directly to the stringers and will be installed before the floor.











    The weather should warm up this week and we hope that means more progress on The Harvester Project!
    Pura vida!

    Matt, are you going to have the radar arch like the Explorer?

    One of the things that is great about this layout is the captain, angler, and/or the mate have fast access to all the rods. In a style of fishing where the drop back is critical, the layout is great to get to ALL rods quickly.

    Awesome work Matt & team.
  • Matt JornMatt Jorn Posts: 229 Deckhand
    Thanks for the kind words. We are intending to duplicated the Explorer radar arch, however we may step the pipe size down from 2-3/4" to 2-1/4"

    The Explorer arch is a little overkill and all that weight above decks creates some listing issues when all the weight is on one side of the boat (this is especially problematic when the client, mate, and captain are trying to get a picture of a billfish in the water during the release)

    Also we will use a lot of pour foam to make the boat full-floatation, which should also help with the listing.
    Pura vida!

    Matt, the foam will do nothing for the listing. It's only gonna add weight and be positive displacement. Positive displacement are just areas of the boat that cant flood and will maintain buoyancy in case of capsizing or leaks. The wider beam and increased displacement will be the reason the larger boat wont list.

    I'm not a big proponent of foam. Even closed cell foam, especially around the fuel tank/tanks. If the tanks are aluminum the moisture that gets trapped between the tank and the foam will corrode the aluminum. I've seen it numerous times. I had it happen on a Mako I had.

    I started smelling a heavy fuel odor but just couldn't find the leak. I finally removed the console and the coffin cover and found all the foam was saturated with fuel. The deep pits in the tank where leaking fuel. If its not going to be around the tanks, or if you're using poly tanks then its all good.
    I have never purchased fish at the market or restaurant and I never will.
  • Matt JornMatt Jorn Posts: 229 Deckhand
    Thanks for the advice Dan and Catch22, and please to all keep it coming. We are certainly novices trying to learn and not trying to preach to anyone like we know what we are doing :shrug

    Fortunately we are still a ways away from the fuel tank install, but we will definitely rethink the foam scenario.

    Do you guys think that the positive buoyancy created by foam floation helps the boat get up on plane, or is that more a function of hull shape and weight bias?

    :huh

    Anyway, we have reached a milestone over the weekend: one console complete:









    Now on to the other console and fish boxes. Wish us luck!

    Matt, your displacement is the weight of the water displaced by the hull in the water. Its a balancing act between the weight of the boat and the weight of the water displaced. Adding weight (foam) will only increase your draft and make it harder to plane. The benefits of the lighter tower would be a center of gravity (CG) thing. Lowering the CG will increase stability.

    I'm not an expert by any stretch of the imagination, but IMHO the only benefits of foam are, it will help the hull float if capsized. "That's pretty big" and it certainly has some sound dampening qualities. The down sides are, open cell foam will absorb and hold water/moisture, and while closed cell foam will not they both will trap moisture and that pretty much sucks especially if that water/moisture is trapped against aluminum. It eats it up pretty fast.

    If you're going to run high density polyethylene tanks then I wouldn't sweat it. She's looking good...:wink
