Assembly

Fit the crossbeams, mast and boom before attaching the sponsons. Wheelchair sailors can then access the main hull to complete the rigging.

Keep the front (short) and rear (long) crossbeam bolts in separate, marked plastic bags. This avoids mixing long and short bolts during assembly.

Put all the loose fittings, trailer straps etc. into a big plastic box. Everything for assembly and dismantling is then in one place (it’s not funny when you get to a distant event and find that the crossbeam bolts are still at home!)

A pair of simple support trestles made from scrap wood makes removing the sponsons very much easier.

Dismantling

Leave as much connected as possible, i.e. tiller lines to the rudder bar, which is carried in the cockpit, so that assembly is much quicker and there is less chance of leaving something behind. Remember to tie parts on and check that pins and shackles are tight, though, as bits have been known to fall off during a journey.

Make sure items are loaded onto the trailer in the correct order: Main hull mounted and lashed, then mast, beams & boom and finally sponsons. Hulls are best held by webbing straps and tensioners, beams, mast and sail by bungees, which don't slip but tighten under load. The sail can be carried under the boat cover or on top of the beams, between the sponsons.

Load the mast with the foot at the front then, if it slips back, the lashings will tighten and prevent it from falling off.

Average assembly/stripping time is 30-45 minutes with practice

Trailing

Make a master check list of everything and go through it each time. It is surprisingly easy to forget to pack the obvious—like the sail!

Keep the boat fittings box in the boat. That way there is less chance of leaving it behind and it is ready for boat assembly at the other end.

A front jockey wheel is essential for moving the trolley and road trailer.

Paint the boat number and name on the trailer, launching trolley, road and spare wheels for easy identification and security.
