Presto’s plans are not - yet - available.
Even if so far three versions of this model have been built ( one is andrew’s one, and two are my own models ) I am still working on final version of drawings.
Most probably final “product” will be a set of plans and/or a woodpack kit of precut parts and/or a booklet .
In any case there are lot of details to be considered, evaluated, and fine tuned.
Just to make an example, with wooden boat magazine staff, we are currently evaluating the possibility to use a small number of thick “lift” planks or a greater number of thinner planks ( both solutions have been tested )
Or, again, we have discussed about the feasibilty of verticla planks instead of horizontal.
My american friends are looking to sell only " first class " objects ( books, plans, kits or coffe mugs ) and - for this reason - all details are carefully analyzed.
Brando’s plans are not cheap ( 30 $ ) , taking in accont we are speaking of footy , but - so far - about 150 sets have been sold.
These semiscale models are pretty ( and quite fast ) but their building is much more time consuming than a much simpler ( and faster ) Hagerup’s cobra or razor.
All considered, not less than 40 manhours are needed for my catboat, and about 60-80 hours for Presto.
Not models to be built in hurry.
For the next future I am looking to reduce building time to a more affordable time budget, both using precut parts, as well studing a semplified design ( Folletto )
I agree with Andrew : building three models at same time is a bigg effort
ps : see here two different plank thickness on presto ITA 13, and presto MKII ITA 21
