Before Raising the Mast

Remember plan drift?  It works by accident, and can happen by design. 

So why would a person steer away from a perfectly good plan offered up by a designer that will yield a perfectly usable boat?   I mean, it would seem that by now there ought to be a boat for every conceivable taste and desire, from racing to puddle jumping.   I mean, it's as easy as jumping on the Internet and looking, right?

Well, finding a boat design on the Internet is kind of like buying a car, unseen, off of Ebay--especially if it's a model you've never owned before.    Now, how did I even pick a Teal?  Well the original idea was to build a Harley 8 (think cheap sailing experience).  My friend James said that, "No, you won't be happy with that".   Now, of course during his build of his Harley 8, the Teal kept popping up as a "neat" boat.  Still James wanted something bigger (he's going to build Michalak's Mayfly 14) because he wants to carry two people in the boat.   The Teal looked really appealing, and before l knew it, here I am.   Not building a cheap boat either; phooey!

Now, is the Teal THE boat for me?  Well, probably not, but since this whole exercise was not born of my "wanting" a boat, it's more a matter of grabbing the most available plan vessel and going for it.   But, that is NOT recommended if you're WANTING a boat.

So, back to the mast.   Why on earth would I not follow Bolger/Payson's perfectly sensible spirit rig?   I honestly can't say, but the spirit rig didn't look too user friendly and lacked one vital element that somebody else suggested I have--the ability to reef the sail or otherwise depower the rig (short of dropping sail and rowing).   Also, a 16 (ok, 15'8" and some) foot mast?  Egad, that's a lot of mast way up there or on top of my car.  Still, it fits the Bolger imperative in many of his "instant" boats of "simple, simple, simple", as in instant, not espresso.

Since I am effectively a newbie, I also didn't want to have too much sail and the attendant hazard of dumping the boat and then trying to recover it.   However, in the future, I might.   That's the point where they say you should build another boat, but why not make the current boat more flexible so I can change things about?  The most changeable thing on a sailboat is the sail rig, and changing that moves the sail's center of effort, which either means moving the leeboard/daggerboard, or moving the mast.   Well, easier to build a multi-position mast step than a multi-position leeboard, which would be a lot easier than a multi-position daggerboard or centerboard (though it's probably been done).

Well that's my story and I sticking to it.  The initial sail rig will be a balanced lug.   It's also a simple rig, though probably not a as simple as a spirit, since the lug requires some extra setup and tensioning to work right.  However it runs on a lot shorter mast and is a lot simpler to cut out (yes, the good ol' blue poly tarp special).
Eventually I might try the gaff with jib that the Annas Discorse has, simply because it looks a lot more "boaty", but it may be a poorer performer.  Might not even get that far, but I will get this boat built--otherwise I'd have an interesting half built thing in the backyard.  Besides, I've already ordered the epoxy (ouch!) and it's on it's way as I write.

Next time I'll put up pictures of what I did (on the mast step) and let others rate my wisdom on that.  Still, it's my boat and if it all comes out wrong (or right) it's going to be my problem or success.  Your mileage will certainly vary.

Bottoms Up!

Well, with all this fiddling, you think I would put the bottom on this and get a move on.  Okay, hint taken.

Sawing out the bottom went fairly quick, though the final result came out roughly a 1/4" oversize overall.  That's not too bad, as that beats coming in under size.  I did have to wait a day to try to bind in a split in the chine (keep the knots facing in--the only knot and bang, the only split.......   I tried to put PL Premium (think an extra thick version of Gorilla Glue) into the cracked piece, cover with plastic wrap, and then clamp down with a piece of luan.  Well when I pulled the clamps, the joint lasted a whole five seconds before springing open again.  Probably should have used Titebond II.

Yeah, I thought I had this crack beat with PL Premium--5  SPROING!  Keep those knots on the inside folks. 


Well, since the split's going to be a pain, may as well put the bottom on.  Must note that this boat is gifted with "plan drift".  If you'll note, we had that bit of bother when we cut one of the sides in identical fashion.  This was resolved by cutting off the offending ends of the sides and putting longer butt plates on.  Okay, that's not bad, but what about those temporary frames than were glued in, and sank flush to the bottom of the sides......   Ahhh, that's a bit more interesting problem.

Turns out the 8 foot center portion comes within an inch of each of those frames, and of course there is no room for a traditional butt plate (as spec'd in the plans) to fit.   Gee, an inch?   Well I did have plenty of 1x2 stock and since  frames almost come down flush with the sides, what about just attaching the 1 x 2 to the frame and use that as a butt plate???  Well why not.   The items were cut and fitted (more on this), glued and screwed on and then allowed to cure a little bit.   When things were set up to my satisfaction, James (who was over since he wound up taking some glue home with him) helped me fit the bottom, starting with the bow portion.
This gives an idea of what the bottom butt plate came out to.  It is glued and screwed to the bulkhead and the bottom sheets are nailed to that (bedded in PL Premium).  Also shows to better effect the off balance cut of the side butt plates.  Oh well.

All sheets were laid on large beads of PL Premium and then nailed down with 1 inch nails.   What! no bronze nails?   Well, in the time period of building this boat, getting bronze nails (which won't rust if exposed to moisture) were a mail order item and the boat had progressed a long ways without bronze nails--so onward.  However, if I build another craft, I will go through the bother of ordering bronze nails for joinery, and copper nails for any clinched nail work (such as putting on butt plates).

We got the bottom on in very quick order (the advantage of working with two people).   Of course with the bottom laid down, without mishap, it was time to let the glue dry.   This gave the opportunity to pore over sail plans, as this will directly affect how we deal with the next major part of the boat--the mast!
