Small progress update. 8x20 sheets of 5086 aluminum are still backordered, so I've procured a couple 4x20 sheets of 1/8" 5052. Waited 6 weeks for this stuff to arrive from the manufacturing plant. This week I've spent a bit of time modifying a boat trailer into a semi-flat deck so that I can transport the materials from the supplier to the bending/forming shop.
I cut all the roller tabs off the trailer, then re-spooled my welder for steel. And switch the gas from argon back to co2. Then I welded the old tabs to the crossmembers to gusset and allow securing of my flat deck. Well, not really a flat deck, but rather two 2x12" planks 16ft long so I can secure the aluminum for transport.
The deck beginning to take shape. Pic taken just before front crossmember added.
The 'deck' is secured with 3/8" bolts, and recessed so my materials will be able to sit flat.
This morning I headed to the metal supplier, and their shipping department helped me load and secure the stuff to the trailer. Then off to the bending shop. Their backlog is 18 working days, so I have a few weeks to modify the trailer yet again, so that I can transport the hull-halves back home again.
Quick sketch of what I'm having done. Note, deadrise angle is defintely not to scale. Planned size would be 1654 with 10-deg constant deadrise, mod-v or garvey style hull.
The hull design is mostly based on a Garvey design, but I've added 3" chines to hopefully get some grip in turns, and also stiffen the hull significantly in the chine area without adding material. Not sure if I will need ribs or strakes along the bottom of the hull, I may wait til water testing to find out.
In the meantime, the plan is to pull the trailer decking off, then re-use the 2x12 to build the jig for the hull. Also, time to dismantle the waverunner, and do measurements and layout. I want to build my own water inlet as well, but we shall see what the prototypes look like in the next little while.
I'm getting excited again, now that materials have finally arrived, and dropped off at the bending shop. The fee for 16ft bend with 1/4" radius is about $100/bend. But it would save a lot of welding wire and gas, so should totally be worth it.
See you on the water,
