All-Aluminum Quarterdeck HybridFor the past year, I have been using spineboard hakas on my TI. Based on my type of sailing, I found them coming up a little short in a number of areas;
1) The bottom of my spineboards are not flat. That and their natural slipperiness made them time-consuming to secure.
2) I prefer to launch from docks with the amas folded in. This was difficult, at best, with spineboards.
3) I found I am a real chicken and don’t like the haka positioned far out from the main hull. With no tramps, I picture myself falling off the boat into Lake Michigan as the TI sails serenely away.
4) I am a strictly a day sailor and never used the front half of the haka for storage, etc. My preferred seating position on the haka is roughly straddling the rear arm.
Luckily, I had some nice anodized rails available at no cost. Borrowing heavily from ideas on this forum, I designed a quarterdeck hybrid haka . It has a 12” x 30” seating area with handles and a non-skid surface. The center rail is reinforced with a four foot section of 1/8” gauge U-channel. Even with the free rails, aluminum bits and SS hardware add up fast and I invested $80 out-of-pocket for the pair. Each haka quickly attached to the front arm with releasable zip ties (125 lb test) and ball-end bungees in the rear. Even with this minimalist design, each haka weighs 12 pounds, so it’s tough to beat the strength to weight of wood.
