The site should ideally be in the sun some. This means that the sun, especially in the morning and shade in the afternoon. This ensures that the pond is too hot in the summer months. It will also help algae from getting out of hand.
Hard or soft boot? In my experience the best soft lining. The hard-line pre-formed and difficult to level. When you install a preformed ship many of them are built in the factory shelves and different levels. Dig a hole larger than the size of the entire surface of the pond and the total depth. This makes a lot of digging. Dug and the soil is level, install the liner and began to fill. Be more than a re-fill with you, so have the ship move. Try to pack down as you go. Placing water in the liner will help to anchor in place while you refill. If you live in the territory of which have been frozen in the winter temps, NOTE: liner drive can be popped out of the ground during the winter.
A delicate ship that gives you more flexibility. By design, the layout and the edges are easier to conceal.
When digging into the boat gently to install a pool spray paint on the ground form, start digging. Also be a level as possible, but the boat is very forgiving and gentle would be subject to any minor bump or Divette. To install the rack in the pool, you can dig into the wall of the pool or the use of materials such as bricks to make shelf. A pond underlay material is very important. This protects the ship from roots and rough edges. If you have a stone or other rough material to the pad edge or both edges of the boards, so that they would not rub against the ship itself. When you install a soft liner to get down and smooth (you should get in the pond) and work your way up. Again, the water film will increase pressure and help reduce wrinkles smooth out. If you are building a waterfall, running the software under a rock the ship and into the pond. Make sure that the overlap in the pool a little better. This reduces the amount of water loss.
With hard or soft padding do you want to cover the edges with a kind of boundary stones. This is for decorative purposes, when a hard liner, but with a soft lining border rock is a must. This will anchor the ship in place and keep the edges from moving or slipping. You can use natural stones like slate or stone for a natural look or a more contemporary, cutting precast concrete wall caps for a clean custom look.
