Idlewild 12/16/05: Communications at sea

I am getting more impressed each day!  They are using Sailmail--which has 11 stations world wide and is far more limited than Winlink  (HAM radio 43 stations world wide, and far more frequencies scanned) both on SSB.

I have had success with keeping in touch with several circumnavigators every day via Winlink or sailmail.  (and it costs a fraction of satellite communications).

As for the weather--no formal routing service.  (This may become very critical as they get into the Western Pacific, with typhoon season)  My personal experience is that a dedicated Weather fax (Furuno) was the best way of getting weather (along with high seas reports and BBC--and similar--radio services.  I would opt for the dedicated fax if doing a trip currently, even if I had routing.

I love the comment that the World is still a backward place--which it is, but many of us do not really realize it.

I also am very interested in the costs. The building of the boat is a project which could be undertaken by any skilled welder or wood worker.  The interior appears to be quite utilitarian.  I would not be surprised if this boat could not be replicated for well under $200,000 and some labor on the owner's part.  However in plywood it would be much cheaper.  A quick calculation shows that plywood costs about 25% of aluminum for raw material.  For just the hull (including frames--rough calculations show about $7500 for plywood and $30,000 for corrosion resistant aluminum) However the use of wood would require Epoxy and cloth plus fastenings, and bring the cost closer to 35% to 50% of Aluminum.  The engine at 55 hp could come in at around $10,000, Gen set $8,000--you get the idea..
Of course you have to add your own labor at $3.00 an hour (about what amateur boat builders "earn" when they sell their projects if well made).

Comments?
