Design trailer cruiser /1. hull

I like a open plywood multi* trailer cruiser for safe hikes with camping gear.

It should be operatable for 1 person both on land (!!!) and big lakes. Hull weight is an important factor.

Possibly maximum weight 80Kg's (~180lbs) handled with support wheels or trolly etc at beaches etc.

1. Is 80Kg's possible to handle on land for 1p? More, less? (if trailer can't be driven into water)

2. What would you consider to be max beam and nice (acceptable) to row?

3. According to weight and beam... what maximum LOA should it have?


*(sail, row and 2-6hp)

 

Looking back at my cat period;

We had a trailer for on the road and a 'beach trolley'. The cat ways in at approx 180-185 kg's, is 2.60 metres wide and 5.52 metres in length. Mast Height: a staggering 9.08 metres (from waterline).

I could handle this cat by myself; sailing, behind the car and on the beach trolley. Only rowing is not an option.

This to give you an indication about max size of a boat.

(The temperature was something around 2 degrees celsius... That's why we wore the caps)

 

Do you think that I put the weight limit to low at 80Kg's? What weight would you suggest as a maximum for an avarage man?
