It is difficult to find a trailer to fit a classic whaler, because they need to be supported by the keel rollers. The bunks are not used to support the boat weight, and should be adjusted to be about 1/4" away from the hull, enough that you can rock the boat when it is sitting on the rollers Most keel rollers will collapse over a few year and no longer allow the boat to roll on and off; they allow the boat to then rest on the bunks. This increases the effort to launch and retrieve the boat. After replacing my rollers 5 years +/- with Stoltz rollers, ( Stoltz Industries, Inc | Polyurethane Rollers for Boat Trailers ) that problem has gone away. To be certain of aligning the boat in the centre of the keel rollers, you can either use self centering rollers or install side boards. I have a friend with a 16ft Whaler that uses a combination of bunks in the rear and rollers near the front that seems to work well for him. I believe it was purchased here in CR at Campbell River Boatland so most likely a Roadrunner.Boston Whalers should not be trailered with an all roller trailer. They should have a trailer that is fitted with keel rollers as well as bunks. Hence, the boat's weight is supported at the keel and the bunks provide lateral support. It may be difficult to find the right trailer sitting on a lot. I have had good experience with Highliner Trailers in building the right trailer in the past. They have several dealers on the Island.
Is that the correct way to trailer a whaler? Thanks.
Perhaps a few more keel rollers, but looks ok to me. Here is an article that may help you out. Classic Whaler: Boston Whaler: Reference: Trailering: Trailer Set Up (continuouswave.com)Is that the correct way to trailer a whaler? Thanks.
