It was interesting to read Jon's "field report" on the KISS vs. Air-X re: noise, as we had an opposite experience. Spent parts
of 2 days in the cockpit
of a 35' Warrior with their new Air-X pole-mounted about 10' from our ears. The solar
panel would keep the line voltage up, which in turn meant the Air-X would only idle along until the fridge kicked in. That dropped the line voltage and the monitoring circuitry in the Air-X would spin it up to generating speed...which would then be reversed when the voltage climbed again. This went on constantly. Everyone in the cockpit
(6) was commenting on how unobtrusive the blade noise was; certainly never interferred with the conversation and it wasn't anything like the 403 2nd generation model.
The Warrior's skipper
was very meticulous and I wonder if a difference that would explain Jon's group's observation but also mine was the condition of the blades. These carbon fiber blades come from the mfgr. very rough; I've found I can reduce the noise off our first-generation AirMarine 303 wind gen by sanding
the blades, blade edges and especially the tips down smooth and then waxing the blades. Perhaps the Warrior's blades were smoothed by the skipper
(I never asked) while the boat Jon was next two had older blades and/or blades not 'spiffed up' in any way. Don't know...but when next in the States with WHOOSH, I'll probably be switching to an Air-X (better output, smarter circuitry) in part because of that experience on the Warrior.
KISS gets many positive reviews
- and a few quality negatives as their "production line" are a group of Trini teenagers down in Chaguaramas Bay) - and I would consider one if it wasn't for the fact our unit mounts at the mizzen masthead, which makes the AirMarine's smaller size a real advantage.
