All that is what I did
Except I starte with the seats and seat pedestals...in the right place for ME.. ie my reach to the helm, when turns just misses controls etc..position to give best room.. both seats
I am thinking of making a dummy frame in wood, to try different shapes.
Then its a simply a marker pen and and tape measure.. I took the height of our tailest son for head clearance
1/ at helm and 2nd m seat...and distance moving left and right... this also determined the angle back of screen to a certain degree
2/ the distance back from the screen for back edge.. and again height
3/ The area the side clear cover, and fold back . or rather forward..where the frame mounts and sits.
Then with all that marked when on the water check it works, espec the frame and side clears...
You also mark on the top of the screen where the zips come down to divide front clears.. espec the section in front of the helm
THEN go to your upholsterer with measurements and the VELT pen markings with little notes beside what they are for.. and an over all pic of something very similar concept.
Once thats sorted and bimini made while out on the water, with a felt tip pen, mark position of rod holders.. those rod fishes from, their angles etc AND those where you ring a fish in , drop rod in the well positioned holder ...
And the holders convenient to drop rod in next to bait board to re bait..
And those positioned back out of the way, that just cleat the bimini to store rods
Confirm out on the water every position down to the last 5mm before committing...and back on land.. eg store holders just close enough sinkers/ reel handles dont foul the reel / rod next to them.
Its all called " work hard at being lazy"
PS I dont have or need a rocket launcher.
My stowed rods fit along the the top and bottom sides of the deck.. doubled sided velcro on the screws that hold the side panels on.
And from the floor , angles from the bottom of the helm (and same other side) up the bimini frame and just tips at the rear top side edge of the bimini another 2 (4 in total) longer soft bait rods are held in place with double sided velcro
Their are also another 4 in the cabin for short rods.
So seat positions (and heights).. and confirm in real life on the water.. espec the front edge of the skippers seat.. stand lean back against.. and install
Then bimini.. and install
Then rod holders
