Trawler(fishing)
A trawler is a fishing boat designed for the purpose of operating a trawl, a type of fishing net that is dragged along the underneath of the sea (or sometimes above the bottom at a specified depth).
A trawler can also refer to a cruising trawler which is a recreational boat as it resembles a fishing trawler.
Modern "rock hopper" nets have heavy rubber wheels that allow the net move slowly over rough ocean bottoms without tearing on rocks.
Sailing trawlers can trawl at depths of 55-75 metres, but modern trawlers can often trawl to 900 metres. Sizes of modern trawlers vary from 2,500 to 3,000 tons.
Fishing trawler,made up of wood was invented in Brixham(in England) in 19th century, which is the largest port in the South-West .

Pontoon
A pontoon is a flat-bottomed boat or the floats used to support an arrangement on water. It may be simply constructed from closed cylinders such as pipes or barrels or made-up of boxes from metal or concrete. These may be worn to support a simple platform, creating a raft. A raft supporting a house-like structure is single form of houseboat.
Pontoon boats usually run slower and are less likely to cause harm to themselves or other vessels, and are thus less luxurious to insure. As such, they are the most admired vessel style for rental operations. They also present the largest value in terms of capacity to price.

Longboat
His longboat should not be confused with a Long ship; or with a narrow boat. In the days of sailing ships, a vessel would take a number of boats for various uses. One would be a longboat, an open, mainly rowing boat with eight or ten oarsmen, two per spoil. In other words the longboat was double banked: its rowing benches were planned to accommodate two men. Unlike the vessel or the cutter, the longboat would have quite fine lines aft to permit its use in steep waves such as surf or wind against tide where need be.
It had the double-banked understanding in common with the cutter. This was possible as it had a beam alike to a cutter's but broader than that of a gig, which was solitary banked. The longboat was frequently more seaworthy than the cutter which had a fuller stern for such load-carrying work as laying out an anchor and cable. In a seaway or surf therefore, the cutter was more flat to broaching to.
