Pat, They are making a killing even at that price as it takes them only one day and it is pretty much just one guy doing the work. However, it was still worth the cost when you compare it to the time

Pat, HHN uses fairly large timbers for a boat our size - roughly 8"x8". It gave me just enough room to lay on my side, and use and grind the old epoxy back. It was gruelling work and OSHA would defini

Paul, The keel did not yet have the bottom paint applied to it in the picture I posted. The gray color is the epoxy coating.

Pat, Soda Blasting is significantly less aggressive then Sand Blasting and is much less likely to cause damage to your gelcoat. Personally, I would not have my boat bottom Sand Blasted. When I was con

James, Assuming you have the OEM Amel bumper, the bumper would likely just rip off the back of the boat if you tried that. It's made from some sort of foam rubber and held in place by just two M8 bolt

Arno, Voltage may not be as bad an indicator of SOC of LiFePO4 batteries as you might think. Here's a quote from the owner of MV Tanglewood who has had his LiFePO4 bank in operation for about ~18 mont

Scott, Thanks for taking the time to reply. I have read your posts with great interest and they have definitely helped me in planning and implementing my own system which shares many of the same compo

Arno, No problem. That article that I linked to by Compass Marine is by far the most comprehensive that I have found regarding using LiFePO4 batteries in a marine electrical system. I have read it man

Matt, That is true and Firefly batteries are technically lead acid batteries. They are just so unique and unlike "traditional" lead acid batteries that I put them in their own category.

Joerg, I think you ask a great question. The only information that I have been able to find regarding anything remotely close to answering the question of what actually happens if you keep LiFePO4 bat

When I asked Dessalator's USA rep Mark Fruehauf at Balcen (info@...) about how best to winterize our watermaker I got this reply: "For winterizing I recommend doing a fresh water flush and then

Porter, That's part of the issue. If you read each manufacturers instructions for how to store their LiFePO4 batteries you will get very different answers. There is some level of commonality between s
