Layout software, not marina management.

Dock Builder

  • Slips, finger piers and walks
  • Take-off and quote
  • Permit and proposal drawings

Marina management software

  • Not in Dock Builder: Slip reservations and rentals
  • Not in Dock Builder: Tenant billing
  • Not in Dock Builder: Fuel dock or store sales

No wave, load or structural analysis, and no survey data: depths come from soundings you enter. The automatic take-off assumes wood-framed floating or pier docks.
