Dear Client,

Please choose among the following services if any are of interest to you:

$45/occurrence - We open your boat (hatches, doors, windows) in the morning and close it in the afternoon.  It includes a visual check for any anomaly that would be reported to you. It does not include fixing the eventual anomaly.
$65/occurrence - You must provide us with a clear description of what/where to check. It does not include recharging your batteries. 
$100 per block. We will drop cement blocks where you tell us to. Each block is about 1.4 tons. Straps to tie your boat to the blocks are not included. You may provide them or jump to the next section if you need us to provide them.
Straps are $95 each. You may keep them when you leave.
Once your boat is here and we will have inspected her, we will provide you with a quotation.
