Aye aye, Roger and Chris.
Lighter is better on the water and on the road.
On the other hand, while we have your ears, please bring a better, larger downwind sail to the Weta.
Happy new year to you too.

> The dolly has seen many improvements over the years with increasing the rail sections from 90x20 to 100x20, larger diameter wheels with heavy duty tyres etc.
> The next run of dollies will see new hull supports giving less resistance launching in surf and an extra aluminium plate section spanning the axle area to eliminate the HAZ part of the dolly where the failures have occurred.

> These improvements will not solve the bending situation unless careful thought is put into strapping management.
> Heavy duty ratchet straps are not to be used on a Weta. Simple hand tensioned straps with no mechanical advantage are best. The Weta are very secure in their moulded supports and just need to be held in position without bouncing. We strongly recommend to trail the boat free of any equipment in the cockpit, however provided the dolly is correctly supported, you can tie the sails in the front of the cockpit.
> It seems many issues arise from Combi trailers where the dolly is unsupported behind the axle. A Combi trailer is fine if it has light suspension to match to absorb the bumps.
> Trailing a Weta on a double axle 2 ton trailer without supporting the trailer full length will end in tears. In this situation take off the beach dolly wheels and put chocks under the longitudinal rails.
> For a lightweight Combi trailer you need just one strap over the Weta main hull in front of the beach trailer axle area.
> You should not only tie the bow of the Weta to the beach dolly but you should strap the bow of the Weta onto the road trailer. This will stop some of the bouncing on the rear support.
> The ama's are fine just by using the mainsail downhaul S hook to secure the grab straps on the front of the tramps and the mainsheet S hook for the rear tramp grab straps.
> If your beach dolly does need repair we suggest welding a 400mm aluminium box section or 5mm plate to strengthen the area around the axle. This can be easily done on the outside of the main rail or if there is no room on a Combi trailer you can cut a section of the cross beam and slip it on the inside. This should be an easy fix for a local engineer that is capable of welding aluminium.
> We hope this is helpful as we are not trying to cut corners skimping on materials but we want to manufacture a trailer which compliments the function of the Weta.
> We would like to thank you for your continuing support and wish you all well in the coming season.
