The Sport of boating is one of the most fun American activities in the warm weather months. People buy and rent them in all shapes and sizes. They can cost as much as a few hundred dollars for small aluminum boats used for fishing or rowing and up to millions of dollars the very wealthy may invest in their spacious yachts. Other than springing a leak and submerging a small aluminum boat, there is not much water damage that can be done to the inside of one of these. The much more high priced yachts, cabin cruisers, and house boats are a whole different thing.
When these more costly vessels are in great condition they can be so exciting to ride up and down the waterways in. Some people go out in them all during the year. If they are not in use, they are usually always kept resting in a boat slip in a marina somewhere. Smart people should check over their boats entirely prior to being left to sit in a boat slot, sometimes for weeks or months before they will be taken out again. Of course, those who own those really costly yachts will most likely get someone to do this for them, but many boat owners will do this job themselves.
Even when the boat has no leaking when it is docked in the slot, many times because of very rough rain and wind events, boats could be tossed violently around in the mooring slot. This may cause it to be punctured, or if enough water gets inside the boat, it can become submerged right in the slip. Sometimes the water at a slip might not be that deep and sometimes only one side or end of the boat will sink, permitting the other end or side to be left sticking up. Either way it is a bad situation.
Less elegantly made boats, such as a pontoon or fiberglass fishing boat, should not sustain irreparable water damage to the boat interior. Often times the submerged motor may be savable. Normally boat owners will have insurance and it is likely to pay for the cost for the boat to be raised and any fixing amount, if it is fit to be saved.
Larger boats like house boats, cabin cruisers, or yachts can have many things such as appliances, carpeting, furniture and other features that sustain water damage and are not logical to try and save. In the majority of events where a boat is horribly damaged, they will be totaled out and the owner will get a brand new boat. If Mother Nature is the reason for the damage in many boat sinking occurrences, there is not a lot that may be done to stop this other than keeping a boat in dry dock for the season it is not being used.
