Thanks all. In reply to the paint:
The entire hull is done in 2 coats op West epoxy then sanded out. Then I faired out some spots with West thickened with 406 and 407 and sanded again. Then I applied 5 coats of Awlgrip 545 2 part epoxy primer with a roller and brushed in corners as needed. I did these coats hot and then sanded the entire boat at the end. This final sanding was with a random orbital and 320 grit (hand paper in the corners as needed). The interior green is Petit EasyPoxy jade green mixed 50/50 with white, 2 coats brushed on. The beige interior is Interlux Interdeck premixed non-skid, 2 coats rolled on with a 3" roller. The exterior is Awlgrip 2 part LP sprayed 5 coats.

Well, for the most part my Spindrift 9N is done. I am waiting on my fender stock to come in to the store at work, and sail and rigging hardware to come in from B and B. Hoping to go for a row this weekend. Now to spend the rest of the off-season getting my Renegade ready to carry this around on deck and go cruising.

You can look at the thread just under this one for some info on scarfing http://www.messing-about.com/forum/viewtopic.php?t=5358 .
And you can use the BoardTracker search tool in the upper right hand corner of the page and find several threads with much info on the subject of joining plywood.
Once you have decided how you will proceed you can ask specific questions. There is no shortage of opinions here

I built a Spindrift 9, hardly the length boat you are doing, but I still had to join the plywood to make longer pieces. Absolutely you want to join the plywood first! The plans (if like the Spindrift plans) mention scarfing and butt joints w/tabs. Like Charlie I find scarfing to be the choice. He shows the pieces laid out glued up (or in the process off). Here are a couple photos of how I made the scarfs: (posted in order, so they go from bottom up) It looks a lot harder than it really is. We have had discussions on using cutting jigs, which might be helpful for thicker ply, but hand power planes, hand planes and belt sanders seem the tools for 1/4" and 3/8". Good luck with your project.

"A boat is finished when it sinks" That's why none of my boats will ever be finished if I can help it

at the unveiling.........

some more...........

Oh yeah, you probably want to see some picture?

Last fall a friend of mine, on behalf of his son asked if I would mentor his 8th grade class project. Henry is a great kid, and he wanted to build a boat, I'm sure you can all understand how hard this question was to answer :wink:
We got together and Henry showed me a drawing of the boat he wanted to build. It seems this was no ordinary toy boat. It had to be radio controlled and of sufficient size and stability to land a helicopter on. He knew the basic size and shape he wanted, but had no ideas as such about the details for laying out and constructing the hull. That was where I was to come in.
We talked for a bit about the numerous construction methods for building a wooden hull. One suggestion I made was to take the plans for a Spindrift 9 and simply divide all the measurements on the panel lay out pages by 3. Henry liked this idea except that he would loose his raised forward bulwark; a detail that was very important to him. So we figured out how to incorporate this detail while still using Graham's lay out drawings.
6 mm plywood was going to be way too stiff to bend for a 1/3 scale boat that is hard to bend to in the first place. So Henry agreed that door skin plywood would be fine. He was going to paint anyway, so looks wasn't important. The boat would be sealed completely in epoxy and live on a shelf in his room most of the time anyway.
Well, after 60 or so hours of construction and painting time Henry unveiled his ship "Bores" in front of a gathering of hundreds (well, ok, a lot anyway). Parents, relatives teachers and mentors all gathered to see the many projects of this class of creative kids, not the least of which was Henry.

That would be:
9 miles per hour = 7.82078618 knots
Still unreal!!!
Assuming that the miles are land miles this would be true. My GPS uses nautical miles.
But yeah, it is over hull speed either way. They must have been doing a little planing!

I had a 90 lb. Lab mutt I used to take conoeing all the time. He loved going wherever I went and learned to adapt. It sounds like your dog goes everywhere with you. He will learn, though it may take a few snarls or capsizes

After I had my laminated gunwales dry fit/clamped in place I drilled out countersink and clearance holes from the outside at both the bow and stern where they overlapped the breast plate and stern quarter knees (3 #8 x 1 1/4" screws each end). I then drilled pilot holes through the plywood into the plate and knees and test fitted the screws. When I was happy with how it all looked I scribed along the gunwales the entire length to show where I wanted the gunwales to be during glue up. I then removed everything, slathered my epoxy with cabosil on both sides of every meeting pair and put it all back together. I did end up wearing some of the epoxy, but it all layed out just how I wanted/expected it to. I finished by bunging the screw holes. Because the ends were screwed and not clamped while the epoxy set I was able to control how tight they were, which was snug and not totally squashed. The added fastening can't hurt either, laminations usually come apart from the ends.

First of all, many of the trepidations you may have will very likely eleviate themselves as you gain confidence from this forum and your success as you go along. There is a wealth of information here and it is freely shared. The details of the plans Graham creates and the fact that he builds them himself as well is no small step towards your success.
I leave for work in a minute so I can't get into a complicated comment on gunwales. Unlike regular dinghys where a sprung solid one will maintain its shape the nesting dinghy will have its shape altered when cut in half if it isn't laminated. But don't let the gunwale details stop you from starting, there is plenty of time to discuss them before you get to that point.
Enjoy the process, its fun!

There are polyethylene tanks available in small sizes for permanent installation.
-
I believe you would have to mount the tank in a permanent manner and add a vent line to the exterior of the boat to be compliant. But in answer to your question....I doubt it because it wouldn't be compliant.
-
You can also click on that little piece of paper to go to the last post that you read ... so you don't have to page through several pages of posts you have already read.
Now he tells us. I knew what it meant, but not what it did! :oops:

No idea when my next boat is, but I'm gunna try that next time. When I think of all the blood I shed carefully untwisting the wires to get a good lead to hit with the torch when I could have just cut them and zapped em...... Great idea Charlie! Sometimes things are so simple we overlook them in favor of what has always been done.

Varnishing is therapeutic. If it weren't no one would spend the time it takes to do it right. Enjoy each coat and revel in the last one!

I can't wait to become a grandfather, I wanna build one of those!! Stuff like that has a value that no one can measure. It looks great!

Scroll to the bottom of the B and B Yachts Forum page and you will see an explanation. In the case of the animated symbol it means that the thread is popular.

Ventilation will be the challenge though.
Cartridge respirators can help. There aren't as good as supplied air, but better than nothing.

Buying them from someone else wouldn't be right would it? I thought 1 set of plans 1 boat. At least that's how I understood it. Guess I'll just wait and hear from them when they get to it' date=' weathers not that great right now any way.[/quote']
I certainly agree that the designer deserves a royalty for every boat built. If the design is so clever, practical, beautiful or what-ever that it sells so many sets of plans that all design efforts are off-set and continues to sell, then good for him/her. I would give a reasonable time for responding. But if he/she is now neglecting to even respond at all to requests for plans then I would feel no guilt acquiring them elsewhere.

I couldn't decide if I was excited to cut mine in half or horrified.
She looks good! You must have done something right, she nests just fine :wink:
Now its time to come up with some clever answers for when people ask why you cut it in half. Here are a couple I used:
"She wouldn't fit easily in the shop for the rest of the work so I cut her into workable size pieces."
"I didn't like how she came out, so I am cutting her up to fit in the dumpster."
When I made the cleats for my center seat I found they interfered with nesting. I had to cut a notch in each of them in the aft section shaped to fit the aft portion of the forward half. Has anyone else encountered this?

The plastic sheet will make the soaked line smooth because you dont want to have to sand it' date=' which is almost impossible anyway.[/quote']
Would vacuum bagging improve on this? Or do you think your stretching technique is quite sufficiant?

Our painter at work was scheduled for a spar spraying session. My boss offered to let me sneak my dinghy into the spray bay. I had one shot at this free spray job' date=' and it was going to be white which is my choice for exterior anyway, so I chose the exterior. Awlgrip can be rolled and tipped, but EasyPoxy is easier.
Hehe, the letter e with an umlaut
