    I would like at least some foam in that region. Perhaps I will partition and use half for storage and half foam.

    You can get perfectly serviceable access ports from a variety of sources. They are simple round plastic frames with a fast thread cap. They extend above the deck or side tank only about 3/8 inch. They are available in several opening sizes, either black or white, gasketed water tight. The last I knew they were in the ten dollar range.

    Next time I go to T.A. Mahoney's I will pick up a couple if they will fit.

    6" and 8" are the most common, though bigger are also available.

    These have a positive latch;

    These are 1/4 turn;

    Also available are access doors, which also have a gasket and many sizes up to around 16"x24".

    Thanks, PAR. I like the round one with the positive latch. I will go for that or the rectangular one. I don't trust the quarter turn one as much and don't want any lids blowing off going down the interstate.

    Just be aware of the expansion/contraction caused by diurnal heating/cooling. Some guys put a 1mm hole in the hatch lid to let air but not water to move in and out of the buoyancy compartment(s). It might be nice to hear a Whooosh every now and again but over time it may push the joint bonds a bit!.

    The darker the colour externally the more heat absorbtion ie black is 90 - 95% whereas white is somewhere between 5 and 10%........

    Coming on nicely.

    Thanks, SukiSolo. I will place a mechanism to combat that stress.

    I got 2 of the 8" version of these. I will vent the chambers by running a very small diameter lined hole through the transom wall into each chamber.

    Just something between Par and me... since 100 years ago ;)


    Hi Hoyte,

    I always try to make the flotation stuff features that will be either usable for something or part of the furniture or structure. You can make a closed cell foam seat for instance, weather you glass it or not, it will add buoyancy. You can add a gun whale all round on the inside made from foam.

    In those boxes, if you want to place specific items you can put a block of foam and cut out where you will place the items in. They won't rattle and each have a place to sit.

    Those boxes may also be nice to have rod holders where you plant the fishing rods in either side of the motor. If you make the holes in foam you make them slightly small so they hold the rods firmly. Or you can make foam rod holders on the inside.

    Lots of ideas you can play with, but finish the boat first, I want to see if it is going to float :D

    You can put an access port with a transparent glass/perspex window in the hull... that way you can see where the fish are (save you buying a fish finder) :D

    There is a feng shui about your design idea. I like it.


    Haha. I already have a fish-finder. She finds them at the market. :D

    As long as you don't bring the ratio 1.618 into it because then everyone thinks you're nuts. I think we have to go through those dimensions again just to rule any possibility out :p

    Oh. You're THAT kind of a sportsman ;)

    The golden ratio is observed everywhere in nature. Why shouldn't it be used in boat design too?
    If you are foaming a largish area, embed some securely capped plastic bottles for cheap air volume, in the foam to save foam cost.

    Well. if you put 1.618 times the foam in a boat it is going to overfill, and the bottles are going to make it worse... :p

    I don't know, I'd guess it depends on how well fed your friends and crew tend to be.

    I watched a race series on youtube, where one boat lost a crew member overboard and was unable to maintain speed without the extra weight on the windward side - and I thought - where's the BIG guy to speed things up a bit eh ! ;)
