LEAVING ENVOY DURING THE WINTER IN THE WATER VS HARDSTAND

Envoy is on the hard in Lefkas marina, Greece and we will be back there early next week.

Having owned Envoy since late 2006 we’ve now left her unattended for periods ranging from about 5 months to 27 months, mostly on the hardstand but sometimes in the water so what are the pros and cons of each for boats in general?
Next week when we rejoin Envoy she’ll have been out of the water for about 6 months so then we’ll report more on this subject.

Envoy on the Ostia marina hardstand, Italy

Firstly it’s much more pleasant in a marina living aboard while your boat is in the water. You still get gentle boat movement (sometimes not so gentle during gales) and it’s much easier and safer to get aboard your boat and load supplies using the passarelle from the dock compared to a ladder from the ground.
In most marinas we can use our own shower rather than the shore facilities and empty the galley sink, neither of which we can do on the hardstand.
Marina hardstand areas are generally rather litter-strewn and dusty so we always find it easier to keep Envoy clean while in the water. But of course below waterline areas are a different story and while your boat is sitting unused in the water your hull will suffer more marine growth than usual.
So far as safety of the vessel is concerned each option is probably neutral. While in the water there is the risk of damage to mooring lines, cleats and hulls during storms, as well as the risk of taking on water if a leak develops. This is very dependent on the location of the marina since many are subject to surges during adverse winter weather.
On the hardstand there is some risk of damage during travel lift operations or from the vessel falling or being knocked over during earthquakes or severe storms, both of which are prevalent in the Med.
Personal safety is better with your vessel in the water as many accidents occur with people falling from their vessel or ladder onto the hardstand below.
In most marinas security is better on marina piers than it is on the hardstand where there are more people coming and going and public access is less restricted.
Cost is another factor to take into account and this depends on the individual marina and their ratio of berths to hardstand area. Sometimes it’s cheaper in the water and sometimes not. Seasonality also affects this with considerable more hardstand area being available during summer months.
Envoy’s refrigeration system has the option of air or seawater cooling but the latter is more efficient so that’s another plus for being in the water.
There are some repairs and maintenance which can only be performed out of water (for example servicing seacocks and running gear) but on balance there is more that can be achieved in the water.
Another negative for staying in the water is the possibility of galvanic corrosion and/or stray current electrolysis.
Osmosis is another risk for GRP hulls and a spell of several months out of the water can only assist its prevention.
