Alan is perfectly correct. However you will please note he used MSD porta potti - these are equipped with all the ports required for deck pump out etc. MSD - marine sanitation device. Not all porta potties have the requisite fittings. the happiest maintenance day on my boat was the one I...

Depends on what is in there now and what is included in the quote. If you are replacing like for like it will be cheaper. If you are not you may need new mounts, coupler, possibly shaft, prop, etc…. I considered a repower from A4 to diesel and was told I would need new shaft new prop new...

What is in it now? peter

A watt is amps times volts. For a 12 volt system then, 1000 W/12 V = 83 amps. They report 1 kW hour so that would be 83 ampere hours peter

there are numerous world cruisers using electric motors is one example. peter

and while we are talking about bows, any suggestions on how to replace the metal fitting on the bow that joins the rub rail from one side to the other? Thanks, Peter

I guess we will need to hear from Greg to be sure, but it would have to be closer to 25 hours than 250 hours? It will be interesting to know! p

Surely the $25k for labour is a typo? $2.5k would be more like it, no? at $100/h, $25k would be 250 hours of work! Peter

I think heating the clay pot will not be too effective. While clay has a specific heat capacity that is about three times that of iron, the mass of the engine compared to the pot is huge. good luck, peter

I have tried this and have one of my efforts installed on the boat. My CAD skills are quite limited and I am not 100% happy with the outcome. The lens has a "taper" to it and I could not get the large flat section tp be perfectly parallel to the printer bed (or maybe my printer was not aligned...

I had a spot on a pac cup boat this summer for the return trip. race was cancelled - i was sad. peter

Lots of good ideas for the companionway. Thank you very much. Now, how about getting the beasts on and off the boat into the dinghy to row them ashore to do their business/go for a "walk"? Appreciate any wisdom the group may have. Best, Peter PS - 60 lb dogs

I have the tall extractor and would definitely go for the shorter more stable one (like the topsider) if given a second chance. The tall one is ok for cars but is a bit tricky to transport back and forth to the boat - you need to wedge an oily tall cylinder somewhere in your car - and I have...

Is it possible you had your A's and B's mixed up? A polar diagram is boat speed plotted versus course off the wind. So the distance from the origin at any given angle is the boat speed at that angle. Another way to think of it is if you plotted the velocity vector with its tail at the origin...
