Bill,
I was getting ready to make a cheap awning that would improve on the boom
tent I use now. I use tent poles laid across boom and nylon tarp providing
a covered wagon look. The problem with what I have now is the tarp is not
big enough and curves down to sharply. It does not totally enclose the
cockpit but does provide sun and rain protection when over nighting or
motoring. I was going to order larger material and fit to size. I liked the
dacron idea vs. canvas or sunbrella. I am also considering different
materials; more like what is used in modern dome tents.
PVC is OK but I would look at telescopic poles or tent design. Go for some
of the poles with shock cord holding them together. When secured dome tents
can hold up to very strong winds. They are very light weight and easy to
store.
I would be interested in the awning piece and perhaps side panels depending
on design.

>>Boom Room Design Parameters:

>>2. Not integrated with Pop Top Enclosure - removes complexity factor
>>and improves economics/ease of set-up.

>>3. Fabric is sail cloth, with roof panel treated for water resistance.
>>
>>4. Roof panel rests on top of boom as main support beam.
>>
>>5. Must have rigid frame at roof panel perimeter; other roof support
>>members TBD.
>> a. Evaluate frame materials for lightweight rigid frame that
>>is easy to store
>> b. Consider aluminum tubes with crimp/socket connections, and
>>shock cords
>> c. Explore design for "yokes" to fit over boom as supporting
>>"rafters"
>> (see drawings if I can figure out how to attach)
>>
>>6. Multiple side/front/rear panels with optional screen and clear
>>plastic sections.
>>
>>7. Side/rear panels zip in place and snap to gunwale; taught snapped
>>panels provide lateral roof support; no need to attach to stays.
>> a. Lower boom slightly to assemble, then raise boom to tension
>>panels
>> b. If using roof panel only as shade tent, run cords/straps
>>from perimeter
>> frame to gunwales for lateral support
>>
>>8. Front panel snaps across cabin trunk top, leaving hatches outside boom
>>room
>>
>>9. Forward edge is in front of mast and inside forward side shrouds;
>>aft side shrouds are disconnected for boom room set-up; topping lift
>>line runs next to mast; roof panel seals around mast.
>>
>>10. Rear panel fastens inside rear stays and stern rail and snaps to
>>gunwale, with enough tension to ensure rain will slide down the angeld
>>surface; evaluate whether a "shoulder" can be created by adding ties
>>to stern rail (similar to how an umbrella tent has outside ties to the
>>exterior frame).
>>
>>Net, the design that Slim has (which Stan made for the original owner)
>>is pretty close to what Stan thinks is optimal. The idea of multiple
>>panel options (solid, screen and clear) gives it the Rhodes
>>flexibility and quality, while keeping sizes down. Where he has never
>>been happy is with frame designs. He leans toward aluminum or
>>stainless with the "crimp and socket" (somebody tell me if there's a
>>techincal term) type fitting and shock cords used in tents. The
>>individual pieces need to be short enough to fit under cockpit seats
>>or in lazarette.
>>
>>Stan is more than happy to have some help in project managing this,
>>which Bill and I are doing for now. Stan will advise as we go. He
>>thinks we should work with small fabricators to get a prototype built
>>vs. working with someone "in the sailboat business."
>>
>>
>>Next Steps:
>>
>>1. Finalize design specs and obtain firm committments.
>>
>>2. Create prototype, beginning with frame fabricator.
>>

>>Please reply with comments and suggestions.
