    I was planning on starting to paint this past weekend and even purchased some oil-based primer, but the guy at the paint store scared me a bit. He was adamant that if I attempted to use non-marine paint on a boat that I would have to repaint every year at best, and at worst the paint would just come off in huge sheets after one day out on the lake. So, I chickened out and decided to let the epoxy cure a little longer and allow for more of the blush to form before I sanded it.

    I did set to work glassing the remaining parts and even started construction on the cabin ...

    Before I started painting my boat, I also agonized about what paint to use. I almost chose Acrylic water based paint after reading the following article: http://www.simplicityboats.com/latexcarnel.html
    In the end, I also chickened out and decided to use Interlux Brightside paint above waterline and Interlux Pre- Kote primer. Below the waterline, I used Interlux Bottomkote.

    So far, I like the results but time will tell how long it will look good. Based on the article I quoted, I very much doubt the paint would come out in huge sheets as your paint dealer said. Houses that are painted with acrylic paint and are exposed year long to brutal elements do not lose paint in 'huge sheets' ��
    I personally think I would have been quite happy with a good quality acrylic paint but I also fell victim to advertising for marine paint ��

    Also, FYI for anyone in the future looking to build this boat, at this point I'm at 222 hours and $4737.75 invested.

    A rainy, cold weekend. I got a bunch of sanding done but no one wants to see pictures of that.

    I did, however, make a first attempt at a hand-made rope fender using the method outlined in The Splicing Handbook. Considering that I used some old cheap camping nylon rope that I had lying around, I think it turned out not too terribly. At the least, it gave me the confidence to order some real rope and try it for real.

    More progress ... got my custom cut stainless hawse pipe / scupper trim / scuff plate / misc brightwork or whatever you want to call them. Just need some polishing ...



    Got one side of the roof glassed ...



    And finally got a coat of primer on the bottom ...





    The primer was exciting, but it sure revealed some flaws ...

    Busy week here ... it went from 35 at night to 65 in the blink of an eye, and stuff is curing really quickly.

    Picked out the final paint colors:



    Got some glass on the last panel pieces. Just the deck to make now!

    Had a weird issue on the hull top. About a 6" by 3" strip in the center didn't "kick" and two days after I glassed it was still wet. I wiped up as much as I could with a rag and then put more epoxy on top of that section. It seems hard as a rock now. It's not a structural piece and it's well above the waterline so I'm not going to worry about it.



    Now it's getting exciting. I cut a fit template out of hardboard for the deck and tacked all the remaining panels in place so I could make sure everything lined up. I'll just need to adjust the deck in a couple of spots by 1/8" or so and I'll be good. I also wanted to make sure all 6'3" 280 lbs of me fit inside well. It's tight but doable. I think it will be fine, but if I could go back I might make the seat boxes 1" lower.

    just as an FYI, the West System pumps do not last forever. Just because epoxy comes out does not mean the right amount is coming out. I experienced the same thing this year on a different project and it turned out the resin/hardener ratio was wrong and it took forever for the epoxy to set. I replaced the pumps and all is good now.

    I haven't been posting, but I sure have been working.

    Got my 20hp Tohatsu, the price of which stung a bit. A few more gallons of epoxy, too ...

    The fit of the deck gave me fits. I cut it three times on the CNC using 1/8" scrap sheets and modifying the program slightly each time until I got the fit I wanted. Now cut for real out of 1/2".

    295 hours and $9354.19 in deep now. I had originally planned on about 250 hours and $7K total so I'm definitely over budget. Those reading this in the future preparing for their own build of this gem be warned :-)

    The boat sure is starting to attract attention from the neighbors. Almost every night I have some variation on this conversation:

    Them: "Is that a boat?"

    Me: "It sure is!"

    Them: "Like, a *real* boat?"

    Me: "Yep"

    Them: "Will it float?"

    Me: "It's a huge waste of time if it doesn't"

    Them: "How can you know for sure?"

    Me: "It displaces more water than it weighs, so unless physics has changed recently, it will float. It might leak if I do a crappy job, so I'm trying not to do that."

    Them: "Good luck! We're enjoying seeing it progress"

    My next door neighbor has borrowed a bunch of my books and is planning on building a drift boat this winter, so the fever is spreading ...

    it is posts like this which TELL THE TRUTH about expenses & hours that give me a good feeling

    John Q reads an advertisement and a poop sheet for a _______ (you fill in the blank) and he sends off for the plans and buys a bill of supplies and thinke that in exactly __X___ hours he will have the project ready for the water/road/track/mountains...

    AND IT AINT LIKE THAT AT ALL

    Many Thanks for dragging us along

    GOOD PICS & GREAT NARRATIVE

    Well, by the time you are finished, I'm pretty sure it will have cost you about as much as mine did. Mine was about 15K (Canadian dollars mind you), so that amounts to roughly U.S. 12K. The website cost estimate was based on 1970 prices I think plus it only took basic structure into account and not what it takes to really finish a boat. They were also using polyester resin instead of Epoxy and the resin is considerably cheaper, but stinks like hell compared to Epoxy.

    As for the amount of time required to finish your boat, you may be surprised by the amount of hours it will take you if you are looking for a glassy finish. After I was done and took the boat out in the sunshine, I was shocked by all the imperfections I could see, but by then, I was so fed up with the sanding, painting, cleaning ad-nauseum that I lowered my expectations and learned to live with the imperfections

    Well said. I've decided for now that the hull needs to pass a 2 foot test (no obvious problems from 2 feet away), the interior a 3 foot test, and the deck and cabin outer a 1 foot test. I gave up on mirror finish a while ago.

    Your advice about the West Systems pumps was spot on ... I bought new pumps and haven't had any more problems, and the difference in pumping smoothness was immediately apparent, so I was probably overdue.

    I primed the inside of the cabin "door panel" for lack of a better term (my automotive background is showing). I want to get the hard to reach areas under the deck primed and painted before I attach the deck later this week.

    While I was at it with the primer I went around and did the hull underneath the rub rail and the top side of the planing fins. It felt really good to have some visual progress after weeks of trimming blobs and sanding.

    I got the aft upper hull side attached last night ... you may have noticed in the previous photos that I had a 1/4" wide and deep trough routed in the top of the rubrail. I had already spent a lot of time fitting that panel, so it was simply a case of filling the trough with thickened epoxy, sliding the panel in, positioning some screws to hold it down, and clamping the top so it would set roughly fair. I pulled the screws out this morning with no issues. My epoxy technique is still improving ... If I had been as careful with the lower as I was with the upper I could have saved myself about 5 hours of sanding and filling.
