On a 20 ft. tender design, not being an NA, I asked a lot of questions (dumb) about the proposed transition from displacement to planning in...
SuenosAzules, Hi, what model thermal imaging camera did you use from FLIR? Thanks, Mark Cat
The system as proposed would not be that difficult to test for heat transfer before installation. The internal tube mixing devices are called...
Bert, for a production boat, all DC LED lights are tested on the bench for acceptance (spectral output, interior design team mockup test), power...
In regards to the power distribution for a larger vessel like yours, the trend I see to loads and power are as follows: 1) For safety with...
In production designs where there is liability: The shore power approach should address all of the failure modes at the pedestal even if an ISO...
Per ABYC shore power connect / disconnect must follow the shore power warning label located at the vessel power inlet. The same procedure is...
It is best to talk to the battery manufacturer about the proposed series and parallel connection in regards to power take offs, cross connect,...
For a 1200Ah house bank I usually discuss the planned layout with the battery manufacturer support engineer. Charging, battery box design, etc....
Would it be possible to summarize your sailboat circumnavigation Cat requirements? In relation to the design presented, I cannot comment on the...
Yes, this is what I suggest. With the addition of: corrosion and failure to bond. Best regards, Mark Cat
In the approach to shore power mis-wiring, do not exclude a high resistance or open grounding (green) conductor. Mark Cat
Not sure if I can add more than what has already been said. Mabruteam provided a good summation for R-410A Options. For new designs, yachts...
I use isolation transformers on shore power input, so single phase 120 VAC reverse polarity is not a problem. However, if polarity is reversed,...
sdowney717, Many newer inverters use an output stage + PWM/Micro that creates a representative AC sine wave, as opposed to a square wave...
For this size HDPE jet boat, if you want to go into production, design for a rotomold. Mark Cat
For USA 120VAC 60 Hz metal case inverters, the case is bonded to the AC output grounding conductor (green wire). This is done to clear an AC...
michael, Very good advice. The welded aluminum tank features are numerous in construction. The tank is removable. Placement of the heaters...
maggie42, Not dealing much with these types of panels, perhaps you could help me in answering a few questions. In making a panel, why do you...
Is the on-demand system attractive because of weight? Its hard to say the best way to heat water on-board unless the vessel requirements are...
