At HydroHoist® we take pride in bringing the most advanced, easiest to use, and lowest maintenance boat li sys-
tems to the market. Installaon of the li is simple due to its lightweight design and ease of operaon.
The following pages contain step-by-step instrucons of the installaon and operaon processes.
The Light Series HarborHoist™ li takes between 8 to 12 man-hours to assemble on average. Review all parts, hard-
ware, and required tools before beginning assembly. Don’t forget: safety rst.
If you have quesons, contact the Technical Support Team at 1-800-825-3379.

Requires careful consideraon
WARNING: could cause harm or damage to the li, vessel, and user
INTRODUCTION
Lis must be installed by an approved HydroHoist® installer. Failure to comply will result in termina-
on of warranty and could cause injury to the user and damage to the li and vessel.
It is STRONGLY recommended that each installer read the manual before aempng an installaon.

PRE-INSTALLATION CONSIDERATIONS
It is wise that the following determinaons be made before installing a HarborHoist:
• Locaon of li assembly (remote or on-site)
• Method of transport from assembly to launch site
• Equipment required to safely build, transport, and launch the li
• Contact points between bunks and the hull (consider strakes and other hull protrusions)
If you plan to build remotely and assemble the li before transport, rst determine the li’s minimum width from
Chart 1. State regulaons may require special permits and escorts for transportaon. Consider how to obtain per-
mits and the cost. Remotely building pre-sub assemblies and then compleng nal assembly at the launch site might
be logiscally simpler.
Other items to consider:
• Does the launch site allow commercial work?
• Do you need a permit to work and/or launch at the ramp or dock?
• Is there a me limit on dock use?
• How will you transport the li from the launch site to the install locaon?
• How much of the li can be preassembled and transported safely?
• Do you have equipment with the capacity to li subassemblies onto a trailer for transport to the launch site?
• Does the nal assembly locaon have equipment to hoist and launch the completed li?
• Is there level ground for nal assembly, or will some assembly occur in the water?
• Verify the slip width meets the minimum requirements of the li width, see Chart 1.
• See Chart 2 for a list of the required tools.
Working through these consideraons is the rst step in a successful build.

*** This is the minimum the li can be for a 4" of clearance per side
**** This assumes you are using a rope mooring soluon. This measurement allows for a 4" space between
the rub rail of the vessel and walkway. If used with a pole mooring system add an addional 24" to the mini-
mum slip width to take into account this system. The addional 24” will allow for mooring on both sides of the
li (12” per side)
