exactly -
a wonderfull syncronisity exists connecting many things -

An interesting series on the history channel by Berk showed inventions of very different sorts over centuries -the successes and failures ,-most importantly how these discoveries and inventions effected one another in development ,-and how interconnected it all is as one could not have been created without other related earlier attempts ,---one builds on the knowledge of another and another creative result of engineering and design often through trial and error process .

really like Gareth's {grobs} 4 hull design -

think it would also be great without a sail -
just as a fold up -cartop paddle-boat with added seat and maybe peddle driven prop and rudder ,--ideal lightweight stable fishing platform or just recreational watercraft as well as alternate sailing craft ,-

He most likely has already thought of the many other applications ---fun stuff

check it out --congrates Gareth !!
