Re: Removable fibreglass doghouse for Micro ?

Hi Kenneth,

Thanks for your thoughts.

I am going to build Micro to plan and this would just be an add for
use in longer passages. Some protection from the elements and a
little extra stowage space. I wouldn't compromise or modify the basic
hull/deck construction at all.

Hadn't thought about the weight of a f/glass structure of this size.
Could get a tad weighty I guess.

I will look at your suggestions.


Cheers,

Paul.

Ha ha!

Thanks Nels!
Hi John,

I was aiming for an all rounder with this.

Strong, but light as possible. Similar to Roger's, but a demountable
f/glass version and still leaving enough aft deck as to still be
useful and not quite as enclosed as the Navigator.

I guess a f/glass structure of that size could start to get a tad
heavy. I'll have to do some calcs.

I also like your idea too and I have ordered the extra Navigator
upgrade with my Micro plans just to get some ideas on how I might be
able to modify it.

Cheers,

Paul.

Hi Kristine,

Thanks for your comments, suggestions and 'thumbs up' on this.

Thought I might be getting into the realms of fantasy here.

I will look further into it as I am building my Micro.

It certainly would be nice to have shelter and extra stowage space on
longer cruises without permanently altering the basic design.

I will try and keep it as light, yet as strong as possible.

Attachment/anchoring points and some sort of mating/sealing gasket
would be needed. I guess these could be done easily enough.

Cheers,

Paul

Nels,

The"skipper" is just part of the delivery crew, with me doing the
steering as Jean Gauthier likes to take advantage of the local
knowledge method of navigating.The real skipper/owner/builder,Jean
Gauthier, is the one taking the picture.....

Ah yes, high times.... WOOPS!....happy times along the mighty
St.Lawrence, ex home/port/playground to the mighty LESTAT :-)

Peter
Paul that would be a great idea you can make your mold
out of tempered hardboard, use light spackle compound
for fileting your corners. Put cut PVC pipe to put in
the corners so they become a wireway for your wires to
your lights. Oh you put the wireways in after you are
mostly done with your glass work.

Deppending on how big you make it you can put a
wireway in the core in the top so you hide all the
wires to your lighting.

Windows can be flat glass and installed in a molded
gasket

Your idea is a good one and a sound one as well.

Blessings Krissie

Paul,

It depends on what your requirements are for the boat. If you wish to
take the boat offshore, even for coastal hopping, then you may want to
build it for the worst unforseen conditions that you may encounter.
Remember, if you are knocked down and rolled over by large seas, the
boat must have the capability to survive. If the boat is to be used
for daysailing and the doghouse for some protection from the elements,
then this is another set of requirements which may not need the extra
robust construction. Roger is prepared to trade off the extra windage
incurred by the dog house for the protection against wind and spray
during long passages. I have been thinking about a coach
house/doghouse modification for my Micro and think that a modified
Navigator coach house would be an alternative. This would involve
covering the existing hatch opening with a "box" covering (lexan) and
then using Bolger's Navigator cabin as per design. This would
eliminate the Major surgery required for a full navigator conversion,
keep the midship bulkhead intact, still leave the original cabin space
and provide and enclosed steering and navigation area. The trade offs
would be less space for passengers and extra windage,

Cheers
John

You might consider contacting Roger and getting his thoughts on any
changes he might suggest. You could likely just bolt it on with a foam
sealing gasket between the joint - just like a truck topper. Bolger
actually suggested this addition for an OLDSHOE.

One challenge I see with Roger's design is lack of sight lines
forward, unless the skipper is standing. When motoring it could be a
significant factor.

One of PCB&F's most recent hard dodger designs that I am aware of is
on the AS39 LE CABOTIN. Photos 17 throught 21 show some
self-explanatory views.

Also photo 17 shows the skipper rolling "something" in his fingers to
share with the crew??

Fiberglass is relatively heavy for its strength compared with wood, especially
if you use solid fiberglass. Plywood is lighter for the same strength, and
it is also cheaper and easier to work with.

Strip planking might work and it would be light and strong, especially if you
use western red cedar. Balsa is even lighter.

You could use foam cored fiberglass to make it light too, but then you'll
spend a lot of money for the foam. Fine if you want the foam for additional
flotation or insulation, but if not then plywood is probably better.

As far as the "removable" concept is concerned, that's a good idea provided
you build the boat strong enough to not need the doghouse for its strength.

Hi folks,

After seeing Roger Keyes Micro with it's doghouse, it got me thinking
about creating a similar structure but made completely from
fibreglass (very light and strong) and made to me removable.

Roger mentions that his doghouse was designed to be removeable so he
could restore the boat back to original should he need to.

It could be made to 'clip on' to attachements and incorporate stowage
compartments, lighting, port holes, lockable companionway and hatch
etc.

Thoughts?

Cheers,

Paul.
