Each of the boat’s intended use affects boat sizes and helps secure the suitable boat trailer width. When going for freshwater fishing or hunting, consider having compact boats. You can have a smaller boat trailer with a width of 7 feet by having a 12 foot long pontoon boat.

Larger boats beyond 20 foot long are the best choice to load more weights, especially for bay boating. Larger boats can ease towing and maneuvering on congested bay and fit to use on open and calm waters.

Always measure from the bow eye through to the transom section’s drain plug to ensure the right boat trailer. Exclude extensions like swimboards, bow pulpits, and overboard platforms for correct measurements.

  • Store boats in the water for long extended periods like during winters. This is more convenient but has risks. Dry indoor storage is the best alternative in this case.
  • Go for dry docking or indoor boat storage in the off-boating season, like in the winter. It reduces the risks and damages to boat hulls and boat trailers and extends lifespan.

The roller trailers work in low tides and shallow waters though expensive. Though costly in maintenance, running parts are not immersed in fresh or saltwater and are thus, less likely to be damaged.
