Snow, Sleet and Storms
If you live in what some call temperate latitudes, theres a good chance you are just about to take your last sail of the season and are well along with plans to haul your boat for the winter. This is an inevitable progression for most sailors who live in communities that budget for snow removal. Getting your boat ready for this kind of weather calls for some clear thinking and a well-developed checklist.
Start by going over the boat, stem to stern, and make a list of everything that needs attention before you relaunch next spring. You might break that list into must-do and nice-to-do, in case you find extra time or additional funds to spend on the boat. Once youve made your lists, decide which jobs youll do yourself and which youll ask your yard to take on. If you have the yard do the work, the more written details you give them on each job, the more efficient and cost effective they will be.
First take all the sails, halyards and running rigging off the boat and inspect them. Either wash the sails yourself with a mild detergent and store them in a well-ventilated space, or send them to your sailmaker. Run the engine to warm it up and then change the oil and the oil filter. Top off the fuel tanks and add stabilizer and biocide.
After your boat is hauled, the yard will pressure-wash the bottom and block it up on jack stands. Its very important the boat is blocked up properly; winter winds can do a lot of damage in a very short time. Whether you leave the mast in or remove it is another important issue; some yards insist that masts come down, while others allow them to be left in place.
If your boat has a keel, it should be supported with at least two sets of blocks that will not move even if the frozen ground beneath them shifts slightly. Some manufacturers provide blocking plans for their boats, and a few include the best set to ensure maximum drainage. Usually, but not always, this means keeping the waterline at 90 degrees to vertical. You can check this alignment with a carpenters level.
In checking the jack stands, make sure the outer two are reasonably close to the forward and aft ends of the waterline. Stands supporting the bottom of the hull should be just below the chine or turn of the bilge with support tubes at a 90-degree angle to the surface of the hull. Most boats are most secure when weight is distributed evenly along the bottom of the keel. Make sure that opposing stands are tied together with at least 3/16in chain.
To finish putting the boat to bed, a good approach is to start from the bottom and work your way up. Clean the bilge with fresh water and check the pump strainers, hoses and hose clamps. If any need to be replaced, do it now or flag it as a priority on your spring commissioning list. Clean all through-hull valves and check that they are operating smoothly. Also check the keelbolts, rudder bearing and steering system. If something needs attention, put it on the priority list for next spring.
