Micro as in Phil Bolger's Micro design, I think.

Correct. Always been intrigued by the Bolger Micro. But, the square sections and blunt bow were a bit too much. So, mine is a bit longer and has the raised cabin from a OZ build and the sides angle out to the lower rub rail, then return to the top, so it is 6" wider, that, running forward, gave an angled bow, a bit sharper..
Stern was angled out a bit, then returned to the 'deck' level.
Laminated up the main mast, mizzen in bits, as the temps are around 0°C. Quite close, after several years of fiddling. Aim to sail her to the Semainedugolfe.com in Brittany in April.

I must fugure out how to post pics. Tried a few times, but Not. Tec specialist, someone else..

Easy enough these days.

1. Start a reply or new post. Put the cursor where you want the photo, then click the "Insert Image" icon that looks like a photo/image of a tree in the menu at the top of the window on the post where you want to put the photo. (A blue globe with a red X is just to the left, and an icon that looks like a filmstrip is just to the right).

2. When you click the "Insert Image" icon, you'll get a box that gives you 2 choices for where to find your photo. Pick "From Computer" and not "From URL."

3. A button with "Choose File" comes up. Click it, and you can browse your computer to find the photo you want to add.

4. Once you choose the photo, click the words "Upload File" underneath the "Choose File" button.

5. It may take a couple of seconds, but a small version of the photo will appear in your post.

Hints: Best to upload smaller files or the upload can fail. I try for no more than 1000 pixels in width or length.

Hope that helps. A modified Micro would be neat to see here.

Just had a search....I believe i will be entering the quirky boat design rabbit hole of Bolger for the rest of the evening! It certainly seems "more boat" than the West Wight Potter i get to use, though why it has a bow like that i have no idea.

Great start Steve. I thought I was quick starter but this is way ahead!!

Look forward to following the build.

Regards Neil

Both of you need to knock it off! Or come do my day job so that I can do something really important, like work on the boat! Got in an hour shaping the floors, but nothing significant. Feeling like my feet are in molasses! But seriously glad you have time to get to enjoy it!

Is now the time to tell Ken my wife and I are off to Tasmania for 3 weeks holiday? (got tired building boats) Lol.

Andrew -- by all means please learn how to post photos -- and then give us a thread about that event. There's nothing like it in the States.

Re: Ptarmigan 17 glued lapstrake yawl

Best of both worlds. A long way off, but, will you be glassing the exterior and if so, how will you deal with the lap end grain? I read a suggestion of a hardwood capping on the exposed plywood end grain?

I will glass the bottom including the first strake. I can radius that chine easily. No need to do more than epoxy coating above that, the bottom will be done for mechanical protection. As for end grain I'll first coat it with thinned epoxy using the manufactures proprietary additive then two coats of epoxy before painting. It worked on the last boat which is now 6 years old

The rudder head is shaped and glued on, fillet curing as I write. Epoxy coating in the next few days. The head is blackbutt and will be vanished, the blade will be painted. 20230308_181027.jpg

I am quite possibly over-thinking the risk of damage, or thinking of the consequences of such. More fenders are cheap insurance. Its the only advantage i see of multi-chine stich and glue that buries the joint inside and out in glass, but, it fails in the aesthetics and from what i have seen, requires a lot of repetition of sanding and filling to look any good to hide the tape seams.

Yeah, this boat was originally drawn as a stitch and glue but it's not an attractive design and I'm not a fan of stitch and glue. I love a nice lapstrake and they're easy to look after, no need for glass everywhere

Agreed. Your lapstrake version will make this boat very attractive. I've built three S&G boats without regret, but I chose a lapstrake as my "forever" boat.

Re: Ptarmigan 17 glued lapstrake yawl

Looking good Steve :-)

Does the 2nd plank just butt join the 1st, and do you need to chamfer the edge of that 1st plank to make the joint clean? It was one part of building my Hartley TS16 that I found very difficult especially when sliding long lengths of thick plank around during the dry fitting. No doubt you've thought this through & have a solution. This looks like it will be a pretty boat.

Re: Ptarmigan 17 glued lapstrake yawl

That's a tight workspace! Reminds me of the little garage bay I rented to build my boat. It worked OK, but you do have to be efficient with the use of space, eh? Looks great so far.

Re: Ptarmigan 17 glued lapstrake yawl

Neil, it's just the same as your current build but the garboards are one flat panel so it will be faired to accept the next strake but then instead of ending up with a traditional strake step the strake will be faired flush with the bottom panel then a second bottom panel goes on, the joint will then be radiused into the strake. From there on it'll be normal lapstrake.

Tom, it's a little tight but not quite as bad as it looks
