Dolly Trailer Combo System

Dynamic’s “Dolly-Trailer Combo” is designed so one person can travel and load/unload their boat without assistance. This system has several options shown in the pictures, including a “spar deck” to store spars while traveling and a “rack above” for a second boat. Add Dynamic’s rolling rack pads and tie down straps and you’ll have the complete setup! This unit has the ability to be tailored to a trailer you already own, we can recommend a trailer for you, or we can build the hole unit and have it ready for pickup.

Modular Rack Systems


ST-Opti-9-3-18-47-60 V2 DimetricST-Opti-9-3-18-47-60 w boats Front viewST-Opti-9-3-18-47-60 w boats dimetricThis 9-Boat Optimist Storage Rack has it all.  PVC storage tubes mounted below with optional aluminum locking doors allow the sails and spars to be kept on the float and dry.  Pressure treated 2×3 wooden runners allow for sailors to pull out any boat on the rack.   This is a great option for privately owned boats – without runners it can be difficult to get upper or middle boats out of the rack, as you can’t climb through the rack to lift the boat out.

IMG_1778IMG_1777Dynamic “Shell Dolly”  Part number 10000-S – 2015 MSRP $235.  This unit allows users to lift the stern of a kayak, canoe, or shell onto the dolly and then pull the boat around by the boat’s bow.  This dolly comes complete with tie down straps to secure the boat and a “kick stand” to help keep the dolly upright when you’re lifting a kayak or canoe onto it.
