Bolger Micro

Hi, I previously had contact with two Micro owning gentlemen from/near Adelaide, Australia but lost contact since computer problem. One was Allen, sorry forgot other name. If you could please make contact again.

Also, Would like to see photos of some Micro interiors set up for solo cruising.

Thankyou,

I have seen two people (on the web) who have reinforced the hulls of
their Micro. The Zeiger's sailed a lee-board Micro. "After punching
a hole in the hull, just above the waterline, we added 1/2" "doubling
plates" port and starboard, doubling the hull thickness to 1" to about
8" above the waterline. It gave us a bit of extra buoyancy."
(http://www.ace.net.au/schooner/zoon.htm#start).

The other Micro saw was being built in England, and had reinforced
sides. I don't know if they boat was ever launched.
http://www.pentode.demon.co.uk/bolger/

When I was contemplating my Long Micro (LM) these builders influenced
me a bit. I opted for .5 inch sides on my LM (which Bolger notes is
acceptable). I think anything greater than .5 inch sides would be
excessive. Why not build with 3/8 inch sides (the stock sides for an
LM)? Or you could make laminate/sandwich sides (two pieces of .25
inch ply with foam board sandwiched between. Plenty of buoyancy but
plenty complicated to make too.

Both Micro and LM are designed with enough floatation to sit high when
full of water. I think about the possibility of being holed in my LM,
but it doesn't concern me much. I'll have plenty of time to swear,
wring my hands, and then engineer some kind of crude fix. Or just
motor or sail towards land with a couple hundred gallons of water
sloshing below.

Have you read Roger Keyes' accounts of sailing his micro off the coast
of Australia? He's modified his micro quite a bit over the years, but
he still sails solo, and regularly heaves-to for the night and naps at
sea. He's been on some extensive journeys in his micro. This says a
lot to me. The boat is a rugged little vessel and she'll take more
abuse than the crew will.
You can read about Roger and his micro in the "files" section of
Bolger7. There are also some good photos of Australian Micros
(in Bolger 7 and one of the other Bolger groups)

Hi again,_

I don't know what a spec micro would hold up to but mine feels incredibly stout. Years ago I ran mine aground at full speed. This is no small feat in a boat that draws a little over a foot of water and I was sure after jumping the boat up on that ledge that she'd been ruined but the only damage I could find was a little curl of lead ( picture a mallards tail ) in the bottom of the keel. As far as seaworthiness mine has been outside the San Francisco Golden Gate in high winds and at least sixs foot seas. The boat was fine but like others have said the real limits are in the crews abilities to sail and endure the physical demands of bad weather.
You mentioned you wanted to sail with your family and here I'll say we did so as a family of four. We cruised for tenor more days at a time in Mexico,in the pacific Northwest and in Maine but the boat is really best suited for two people even as a day sailor.
Again I'll urge you to consider the Birdwatcher especially if your going to trailer your boat. A micro takes time to set up and because of the rocker of the bottom needs a steep ramp to float it off the trailer. With a micro your going to need a dinghy and a motor so add that into the equation when your comparing costs. There was an article on the birdwatcher in Woodenboat and if you haven't read it I would urge you to.
I don't want to give the impression that I think the micro is not a good design I've sailed mine for ten years now and just spent two weeks cruising the Maine coast this summer with my wife. I just bought new sails for her and would find it hard to sell her but that said it's easy for me to see the merits of the Birdwatcher design.

The outboard motor you mentioned earlier will get you home through
some pretty hairy conditions :-)

Your best insurance is to include the flotation as designed :)
.... many do not :-(

(... perhaps for added security include a bailing pump too?)

I'd say 1/2" ought do for the bottom. 3/8" is good on the cockpit
deck and the cabin top which also serves as a deck at times, and, I
think, can do with the extra stiffness. 3/8" could do for the rest.

If you've yet to order the plans from PB&F then briefly include your
queries and concerns about the intended use with the order and
payment - maybe a rough sketch or two to illustrate your thinking as
well. I'm sure you'd receive a reply to that. They may just
say "Nay" or "Yay" to any particular modification, but you will then
know that with authority. They may make further recommendations to
your own suggestions.

I think so, but you would probably knock out a few teeth.
I think maybe my comment about "pushing the Elements to the limit" may
have been misconstrued.
First off let me say I live in Gulfport, MS. For those who may not be
familiar with our geography, we have several barrier islands with
three being a sort sail (5-7 miles offshore). The water depth between
shore and these islands averages around 12 feet (deeper in some
places, shallower in many!). Even though the islands give protection
from the ocean, when the wind conditions are right and the tide is
running in the opposite direction the seas get confused. Producing
short, flat, irregular waves usually up to 3 feet (although I have
seen 6).
Of course a prudent sailor is aware of the weather and always keeps an
eye out for deteriorating conditions, But what if I were on the open
ocean side (South) of an island, which happened to be the Lee side,
and was completely unaware of the Windward conditions until the
fateful return trip?
Per plan, would the Micro stand up to 3 foot seas?
The real reason I wanted a 1" Hull was due to Katrina debris. Efforts
are ongoing to remove more but it is a slow process. I worry that
eventually I may run into something and I wanted the piece of mind
that the Hull would stand up to it without puncture. Maybe I'm
over-worrying...
My intention for this boat is to sail with the family out to islands
on the weekends. I just want to be able to get home in bad weather
conditions if we are forced to by time constraints.
Mr. Lenihan, I have seen pictures of your boat and I aspire to achieve
the level of finish you did with LESTAT. A true Gold-Plater!
I have read a lot of Mr. Bolger's comments pertaining to changing his
designs and that is not what I intended. I just thought thicker was
better...
What about 1/2" Hull, 3/8" everywhere else? With sheathed exterior
will it be beyond the reasonable towing capacity of a 6 cylinder?
Or will the Micro with 1/4" plywood throughout and sheathed exterior
be more than enough for my needs and intended uses?

Keep this in mind; it will be the elements that are going to push
you around, not the other way around ;-)
Most well built boats will pretty much accomplish the task of saving
you.The master and/or crew however may not be able to take as much
as the boat can handle.

Added costs and added difficulty of bending 1" ply...unless you
laminate 2 layers of 1/2"....but then there is the cost thing again.

Micro.

Sincerely,

I'd suggest that you run your suggestions by PB&F. They could
quickly tell you what such a significant increase in the overall
scantlings might do to the Micro performance. I think they would be
quite interested to hear of your wanting "a boat capable of pushing
the Elements to the limit."


It's not just that with the extra hull weight you will have a much
reduced payload, it also may not be as stiff. 3/8" is good, and I'd
guess up to 1" around the bottom would be alright.

The Micro figures of 420lbs ballast, 875lbs empty weight, and 1650
lbs displacement are for a boat constructed from 1/4" ply, and only
painted. Jim Michalak has a rule-of-thumb somewhere that for 1/4"
calculate 35lbs per plywood sheet finished, which comes very close
to the specified Micro hull weight. For 3/8 it's 50lbs and for 1/2"
it's 70lbs (or there abouts), and I think that may be only for boats
sheathed on the bottom.

Thank you gentlemen for your responses. I asked 'per plan' for a
general idea of the price and time involved for a 'workboat' type
finish. Even though my goal is a 'Gold-Plater' finish on a strong
over-built boat.
I intend to use marine grade plywood throughout. 1" Hull, Transoms
and Sides (or would it be better to have 1" sides to about 5" above
where the Transoms meet the Hull and go 1/2" from there up?). 3/8"
Deck and Cockpit.
Everything exterior will be sheathed, everything interior will be epoxied.
I want a true keel with solid deadwood with the ballast through-bolted
into the Hull.
I also wish to beef-up the Deck (such as LESTAT) with three laminated
beams for deck support.
None of this is new and has been done on some existing Micros and Long
Micros.
In essence, I want a boat capable of pushing the Elements to the
limit. One that, if caught out in a squall, will get me home safe.
What are the disadvantages of the added plywood weight?
Any other modifications anyone would use (or did use) building their
Micro?

If you were going to build today...
Micro or Long Micro?
Why?
Bill's LM: $9000 / 1500lbs, empty = $6/lb

Bruce's Micro: $1400 / 875lbs, empty = $1.60/lb


Bill's LM: $9000 / 2400lbs, displacement = $3.75/lb

Bruce's Micro: $1400 / 1650lbs, displacement = $0.85/lb


About a 4x leeway factor for cost there.

I'm sure that these boats have been built for less and for more
depending on builder preferences. My example of a Micro was a quick
rough basic build, though of good materials I think, by a guy who
knocked out about six for family and friends in just a few years in
the early 90's. It is kept on a trailer, not sheathed in frp except
for some taped seams, has original house paint, and has one small
patch of rot in the topsides near the bow which used to protrude
from the garage of a former owner for some years - dry, covered
storage has markedly extended the life of this boat. If it had been
better built and sheathed, who knows, left on a mooring for the same
time it may have stood up just as well.

Just a small percent of the total investment. The price isn't fixed,
my guess is it will be about $150-$200. For exact price, contact: Mr.
Philip C. Bolger, P.O. Box 1209, Gloucester, MA, 01930, Fax: (978)
282-1349

The price of the plans will be recouped many times over in the resale
price, as a boat designed by Phil Bolger is worth something. While a
'self designed' amateur backyard boat is worth about zero.

> 2) How many have been built?

My guess, one or two hundred. Hard to know for sure.

> 3) Per plan, How many manhours in construction?

A huge variability, depending on your experience and your building
style (work boat versus museum piece).

I would take a bet I could build one Standard Micro, 'work boat
finish', in 150 manhours or less. I am sure that many have been
built taking 1,500+ hours.

I personally built my Micro (Navigator version), in 450 manhours, with
a couple hundred hours being spent on cabinetry, upholstery, windows
and cabin finish details. And, at least 150 hours spent (wasted)
doing things that I saw as 'improvements' from the plans, but in
hindsight...were not.

> trailer)?

Again, huge variability. With lots of scrounging and improvised
parts, I spent about $1,400 on the boat. Again, I bet that most
Micro's have been built for closer to 10x that price. Yet, a cheaply
built boat can be serviceable if not immortal.

By the way, I am *very* happy with my Micro since I finally got a
convenient (and coveted) marina berth in downtown San Francisco,
California. She was not nearly as fun to own when stored on a trailer
in my driveway, but now that she is floating in the marina nearby, I
enjoy using her several times a week if only for short pieces of time.
1. A fax to PBF should produce the cost of Micro plans. You should buy
your plans from PBF, since there are some royalty issues with other
entities selling PFB plans.
2. My complete guesstimate is that at least 100 have been built. The
old Common Sense Designs newsletter reported quite a few Micros being
built and launched. I recall that the old newsletters are archived on
one of the yahoo Bolger sites. They make for interesting reading.
3. Per plans, I imagine you could knock a Micro out in about 300
hours. The old CSD newsletters report various building times. But the
plans call for a plywood boat which is glued and nailed together and
coated in paint. Most people opt to sheath their boat in epoxy cloth
and resin. Some people are using MDO (which should save time and
epoxy costs). How long you spend is related to the degree of care you
take during the build. And completing the hull represents about 25-30
percent of the total building time. It's the little, detail items
(interior stuff, deck, spars, etc.) which eats a lot of building time.
I completed my Long Micro this summer after 920 hours of building time.
4. How much you spend depends greatly upon your materials. AC
plywood, or marine ply, or MDO? Epoxy (and if yes, which brand?)?
Hardware? Paint (porch paint, latex, or something expensive?). I
spent close to $9,000 building my Long Micro, including marine ply,
epoxy, buying my sails (from Dabbler Sails), a new 6 hp outboard,
electronics, etc. This price does not include a trailer- I got a
used, flat-bed utility trailer for hauling duties. I cannot dunk it,
but launch my LM with a sling at the boat yard. I suggest that you
look at the materials and figure out how much various grades of
materials will cost. You can score some great deals on older
outboards. Some people opt for polytarp sails, etc., thus saving lots
of money. Like everything else in life, it's all a compromise. But
it's a lot of fun to figure out.

Hi,
I sail a micro in the UK. She was built by a single man over a 4
year period. Her total build cost in 1999 were £6000+ incl trailer
(bespoke) and sail from Common Sense designs.

However she is up for sail for only £1200 excluding engine but
including two rigs - original and junk.

So a secondhand one seems to cost in better.

I have a Micro that has a bad case of rot. If anyone wants a PROJECT,
contact me.abrahams@...
It has a custom trailer (not titled) spars, sails, etc.
I had fixed the rot but it has returned. I'm tired working on it. If
interested, contact me. I figure the trailer, spars, sails, Lead
keel, etc. must be worth $300 but that is flexible. The boat is
actually usable as is. Located in Louisiana.
