At $3k plus installation and spares for a 3 week trip...even that one is pretty steep Andre. Betcha his fuel tank is small too! Don't see many other options though as he will want a minimum of 80 gallons and a SAFE capacity of about 150. Maybe some bladder tanks can be stashed under v-berths and settees instead. Since with a small boat and unfavorable weather and/or problems, the trip could last 4 weeks easily and even 5-6...seems like maybe both a watermaker and some extra tankage would be prudent. I would also be looking at a towed generator or solar to supplement my alternator.
