Sorry for the late reply to these. We had company this week and they just left.
Ok, here goes:
We have been living aboard and cruising (or modififed cruising depending on your definition), for many years now. We have taken some time off here and there, but this is not our first time living aboard, or being mobile live aboards. As such, the day we bought the boat, I had them raise the waterline three inches. We have never gotten close to that waterline, and it may have been an overkill, as even fully loaded, the top of the paint is a couple inches high.
My performance loss is kind of odd since we now are aboard FT with no address or even a dock box (this means that things we might have left in storage or in a dock box or in a car, we now take with us). I would estimate we lose about a knot in 15 kts. However, we can still get to or over hull speed, but it takes more wind (maybe 20 kts). I was motor sailing Saturday, and was were running about 8 kts, with 8.3 the high. We waived at RTB (a member here) as we sailed by him and his wife. So, I can still get pretty good speeds, but it takes more 'power' from wind or motor. Another interesting change is how we motor. I assume this is because of the higher displacement, but whereas before, I could slow the boat down quickly with the motor (like coming into a slip), I have to plan ahead a lot more now. SHe doesn't stop on a dime anymore, if that makes sense?
As it stands, we have enough food for about a month on the boat. THis assumes no outside food. That is about how we stay stocked. We stay stocked that way not because we have to or spends months at far away anchorages, but because we like a variety of things to eat on the boat and a trip to the grocery store is a real PITA (we do not have a car). We try to make frequent trips to keep her stocked up because that way I can haul the canned goods in small amounts on the bike, backpack, or cart. If you wait a week+, then the amount you need to get to restock is a lot more, more weight, and probably will cost a cab.
If we are major conservative, on the hook, we can run about two weeks on water. THis is a periodic shower and conservative clothes washing and dish washing. We can all shower conservatively, every day, for a bit over a week on what we carry comfortably. SO to cross the Atlantic or Pacific, which I have no interest in at this point, we would buy a watermaker.
I think that answered all your questions?
All good CD. yes, same here, lock stock and barrel on the boat. we actually are cruising about 1500 lbs lighter then when I left Seattle in 99. It does make a difference! I was given a water maker several years ago, and have never installed it. Don't want anything extra to maintain. 100 gallons for two goes a long way...plus it rains.
Same with food, a village on every island, fresh is so good. getting pretty handy with the crab trap. Can't keep my wife away from the fishing pole either. I ride my bike also to provision, good work out in the tropical heat. Beer gets a little heavy though..
