How to Shrink Wrap a Boat HDS Carbon from Lowrance - Are you ready? HDS Carbon from Lowrance - Are you ready?

Give your boat 100% protection during the off-season.

Shrink wrap systems are a great way to protect boats stored in the off season, build temporary structures to contain construction dust or cover unused equipment. Shrink wrapping creates a versatile waterproof barrier that stands up to the environment. Completely covering the boat helps to keep out rodents and protect canvas from bird droppings, dust and debris. Because it is heat tensioned, shrink wrap eliminates pooling and sheds snow to reduce the risk of collapsing from snow loads. The tight material remains stable in high winds and will not chafe gel coat and paint.

Dr. Shrink manufactures their shrink wrap using 100% virgin resin with UV inhibitors to maximize strength and lifespan. Three colors are available in some thicknesses to better match the demands of certain applications (see below). Seven different widths allow users to select the best size to meet the needs of the job(s) and reduce waste. Each roll features center folded material to make the larger widths manageable and to aid in draping sheets of shrink wrap over the boat. All of Dr. Shrink shrink wrap is #4 low density polyethylene shrink wrap completely recyclable using Dr. Shrink REBAG® recycling bags or through a recycler that accepts #4 low density polyethylene.

Why the different colors?

All shrink wrapped boats require ventilation. The color of the shrink wrap you choose will affect how much ventilation is required—and how well it is able to stand up to the elements.

  • White: Great for most applications and stands up to the elements a little better. White offers Minimal heat transference and produces less condensation. Ventilation is still recommended.
  • Blue: Ideal for snowy climates, the darker color heats up and helps to shed snow to prevent unwanted snow loads. Users will want to use additional ventilation to control condensation.
  • Clear: Primarily used for green houses, this material can be used for brokerage boats to allow in light for showing the boat. Liveaboards who spend their winters “on the hard” also prefer clear shrink wrap. Since clear shrink wrap allows the most heat transference it requires additional ventilation for condensation and mildew control.

Selecting a thickness

Dr. Shrink materials are available in different thicknesses to suit different applications. Below are some guidelines for the best uses for each thickness. Regardless of the mil rating, all of the material carries 12 month UV protection.

  • 6 mil: Good for general marine use. Can be used inside or outside in areas with milder winters
  • 7 mil: Great for general marine use, smaller temporary structures and covering mid-sized equipment. Able to handle harsher winters with moderate snow
  • 8 mil/8.5 mil: For applications that require a heavy duty material. Great for wrapping commercial vessels during construction or repair or for boats exposed to high snow loads. Used frequently for temporary structures, covering scaffolding and as a general purpose construction applications.
  • 10 mil: Ideal for heavy duty use. Excellent for temporary structures, covering larger commercial vessels for refit or repair.

Selecting a width

For wrapping boats the rule of thumb is to have an additional 6" below the perimeter band to tuck up against the hull to hold in in place. Many users select a width that corresponds to average length of their customer’s boats (including the extra to tuck under the perimeter band) so that they can cut the required beam length from the roll. For larger and longer vessels or commercial applications selecting the material based on overall size may be a better approach. No matter which method you use, you will benefit from shrink wrap being center folded.
