BIGVEE™ replaces the narrow bow stops that have been in existence for the last 80 years. Those old bow stoppers were designed to provide a soft surface for your boat to sit against once your boat is winched forward into place.
Unlike BIGVEE™ most of them offer no or very little guiding ability.
The secondary locking bolt goes through the BIGVEE™ flange and through the hole you drill in your trailers metal bow stopper support arm. Only one of the four pre-drilled holes in the flange will be used.
Choose the most suitable hole for the bolt to locate within. The hole you choose will be the one most centrally located on your trailers bow stopper metal support arm.
