Hello Todd, I built an Expedition. You didnt say if you're building an Expedition or a RowCruser (Colin's reply implies the latter), so I dont know how applicable to you situation my reply will be...

Hello Todd, 6mm will be just fine for the hull panels in the RowCruiser.  In fact, we made our original prototype from 6mm and used to spec that rather than the current 4mm.  As you say,...

Hello Team, After searching the local market in Thailand, it seems 4mm BS1088 marine plywood is not readily available. I’ve checked with multiple suppliers, and it appears that only&nbs...

Thanks for your reply, Angus. But . . .  The crossmember widths per the plans are listed as 10.25".  How will the footplate be attachable to the crossmember if it is 12.25" wide?  ...

For the access hatch openings, I made a rough hole and then traced the precise edge on the underside of the panel.

Daggerboard trunk epoxied in place and sanded fair: I made a template of the daggerboard slot via a graphite pencil rubbing, then transferred that to the seat top panel. This is not the saili...

Added framing for the access hatches:

thank you Michiel, That helps. I'm using the Bic rig so I guess they have something similar.

Guess it depends on the thickness off the mast you're using, they should be called a "deck collar" or similar. I'm using optimist masts and any large nautical shop should have these collars, but t...

Does any one know where can I buy the plastic inserts that surrounds the mast where it passes throught the deck on the row-cruiser?     cheers Hamish
